FX IMPACT COMMON LEAKS AND HOW TO FIX IT

[@Donny_Juanny]

THIS is by FAR the best and most needed video regarding leaks on the M3. Labeling each O-ring with the size is so appreciated. THANK YOU SO MUCH!

[@Airbuks]

You’re welcome and thx for the support

[@dreamnailsbardreamnailsbar6195]

i take the regulator out and change the o-ring but is still leaking

[@Donny_Juanny]

There's multiple o-rings in the regulator. A good practice when replacing one o-ring in the regulator is to go ahead and replace all of them. Less than a dollar each and just good insurance. @@dreamnailsbardreamnailsbar6195

Are you kidding? This is the worst no detail video. Sucks.

@ 2K + for one, there should be NO “common leaks” and ZERO “fixing” ANYTHING!

[@hk2read]

Totally agree!

[@shenmisheshou7002]

While I don't have the Impact, I have a Maverick, and I have come to believe that as much as I love the rifle, it is too complicated. The complexity of the double regulator setup means that there has to be too many O ring seals and every one of them is a point of possible failure. It is not that they are really hard to take apart, it is that I don't want to have to take it apart.

[@JGA-vr5tg]

Merci, pour votre vidéo...et après l'avoir regardée, j'ai repris ma FX IMPACT M3 en .177/4.5 mm car depuis 7 mois que je l'ai achetée, j'ai eu quelques problèmes en plus des fuites. Donc, je l'avais laissée sur le côté par déception à mon avis. Avec le même produit "SOUDAL" j'ai eu la même fuite que sur cette vidéo et en plus une autre fuite au manomètre du régulateur No 1. Après un gonflage à 210 Bar, le fusil perdait 10 Bar par 24 Hrs...J'ai démonté le tout, nettoyé, remis les mêmes joints mais avec un peu de graisse. Pour le moment le problème semble résolu. Encore merci...

[@Airbuks]

I know very little French, can you explain in English?

[@balboaroucky9795]

Salut, je pense que je fais vers comme toi car elle fuit lentement.Je soupçonne joint d'un des 2 régulateurs, sûrement à force de monter/baisser (carabine vidée) la pression.Je vais commencer par controler joints valve, plenum etc etc et si elle persiste, ce sera forcément 1 des/ou les j 2 régulateurs joint h.s....

[@whiteykauai]

Thank you for this vid! I was about to give up and send my 4 yr old MK2 to Utah Airguns when an fb friend sent me this video link. After taking my gun apart numerous times to solve air draining out of the rifle and replacing regulator o-rings. The Valve Rod o-rings at 10:12 seems to have solved the problem. Thanks again!

[@Airbuks]

Nice 👍 well done

[@whiteykauai]

My goal is to get 170 ft lbs on the 35/700 tensioned barrel. I also put in a Huma Slug Power kit and Huma Gen 3 Reg. But, I had a major fail upon test firing. on about the 5th shot there was a huge pop and air blast out of the valve rod hole and transfer port. Hammer/Spring and Tungsten wt. jammed into the Hammer Spring Holder. Any ideas on what might have failed? Thanks so much for being here for us guys! @@Airbuks

[@Airbuks]

@whiteykauai my best guess is that the valve went to far putting more power and the very tiny oring on the end of the valve rod popped. What setting do you use ?

[@whiteykauai]

@@Airbuks I had the gun set at 160 on (never used before) reg. Line 4 on thumb adjuster and 16 on pw. My gun is supposed to use 10x1.5 in reg cavity in main block but since I had a leak that was draining the tank I thought maybe AMP reg had failed. or o-ring in main block. So put in the huma high pressure reg and used a 9x1.5 because that's what Ernest Rowe said in a vid. Could the 9.5 be the reason for the blow out the valve rod and transfer port? FX USA says 10x1.5. thank you for taking the time to help!

[@Airbuks]

@@whiteykauai I would always use the 10x1.5 as original from factory, going smaller will create a issue in my mind

[@robbypro3370]

Great video, I got here because I installed the new hammer and huma dual transfer port, and now I have a big leak. Probably from the bottle oring from taking it off? Not sure yet. The only other time I had a big leak was from the tiny vent hole in the back of the main gauge, it may be leaking through the actual gauge and not the threaded seal area. Just one more point of a possible leak for everyone to check.

It is good to see your channel growing my Friend!! and you fully deserve it, cause you have given so much to the community with your in depth "How To" vids and making us better understand on how to approach and handle our airguns, being FX, Edgun etc. All though being into airgun since being a kid, watching other airgun Gurus, I have to confess, that I have learned so much checking out your vids, and now feeling totally confident in splitting my guns apart....and if i get stuck, I just start one of your vids up on the pad and follow your instructions!

[@airgunmaduk5235]

I thought it was the best in the world as well till recently. I have the exact same setup as you have on the video but in .25cal FAC in the UK. I purchased it in January 2023 and it went back to the distributor at the end of April 2023. They still have it under repair till this day now 21 weeks later.

[@Airbuks]

Sorry to hear that mate , but in my opinion it still is the best 😉 why didn’t you try to fix it yourself

[@MrPyroMaster]

Good video! I had the last one from the "109" O-ring kit leak. The air exited the rear block at the bolt under the magazine holder. The magazine holder let the air out where I didn't expect it. The leak detector spray failed to detect it. So I submerged it in a tub of water. :) The air exited at the magazine release. This diving was not a good idea! One of the pressure gauges was damaged... It is impossible to get rid of water with compressed air! I did not see any damage on the o-ring in question. The metal parts were also intact. So I cleaned the notch and lubricated the o-ring with silicone grease. I put it back on and it no longer leaked. Probably some dirt had gotten under the o-ring.

[@Airbuks]

Good job on fixing the problem 👊 any as you found out don’t put your gun in water 😉

[@oneofthosepeople2101]

Thanks so much for the video. I have a 6 month old impact that has developed a small leak. It also won’t fill all the way, no matter how long my pump runs. Do you have a leak detection fluid you recommend? If the impact won’t take a full charge, does that mean it has a leak in between the charging port and the tank?

[@Airbuks]

The leak can be at a few places , I use leak or gas detection spray from a brand called . Soudal

[@lancsvermincontrol]

A really good and simple video to check your Impact. I use leak detector spray as it is 10 times more precise than soapy water.

[@Airbuks]

[@davebremer3080]

You really break it down nicely and make anyone with common sense feel they can do what you do with confidence to there FX. I have had my Impact2 for six years since the day I bought it I have never had a problem with it until three days ago, at 30 yards, my 30 calibre pellet dropped 5 inches from zero, and the pellet stuck in the wood, which normally goes cleanly through it. I also noticed my gauge on the bottom of the power block reads zero. Anyways I have been wanting to add the 720 plenum and power block to catch up with the M3. It should arrive next week from Huma Air. So I decided to do your leak test started from back to front and a truly thank you for making this video ! was starting to get nervous. I finally found a small leak in my fill port. Just so you know I don’t lose any pressure on my bottle gauge. It stayed steady for four days. just has no power to shoot properly. I am truly hoping with my new 720 on its way to secure this problem if you have any input looking forward to it. Thanks again sincerely Gun Smith, Dave

Hi i have fitted a new huma second stage regulator to my fx impact m3 and ever since i have had a small air leak from the small hole on the side of the gun near the trigger, in your video you call it an atmospheric hole, you said air would leak out of here if the large o-ring right at the bottom behind the second stage reg was damaged, when I took out the old reg there wasn't an o-ring there ?

I just purchased an fx impact Mark 3, 600 mm Barrel 30 caliber, slug liner and slug power kit. I haven't tried the gun yet. The question I have is the spec sheet says 105 shots 30 cal and 124 FPE. Are these numbers related to shooting slugs or pellets? The spec sheet states that 124 FPE relates to shooting slugs but it doesn't say anything about the shot count related to slugs or pellets.

So my MKII is leaking in-between the block and the power plenum. I'd does not seem to be leaking at silvery rings located at the very aft end on the valve rod. I believe you said the on the M3 the sudpect orings are external of the valve housing (and the later modela, w/ the power block, are internal of the block). What about the MK2, are they external of valve housing? To access I need to remove valve knob, housing, rod, hammer, etc.., right? Thank you.

On the MKII the orings are on the outside of the valve housing not inside (3 orings on the silver part ) To access that I am afraid you will have to disassemble the whole impact

I don’t lose pressure but I have noticed my velocity dropping after a few magazines. I will tune the rifle for 860fps and after a mag or two velocity starts going down to 840, 830 etc… I was thinking the o-ring inside the transferport where the probe goes in and out?

[@Airbuks]

🤔 it can be a number of things causing this . What do you do to get back to the desired velocity? Up the reg or HS ? It is possible that your C1 is backing out and therefore kissing velocity or the second regulator not recovering completely but then it should get back to normal velocity if you wait a little longer between shots

I don’t have a video how to replace that I think 🤔, but that oring is in a difficult spot indeed . Also hard to show on camera while fiddling in the hole

Firstly, excellent video 👍. I've got a reasonably fast leak on a MK2. I lose about 40 Bar within a few hours from 250 Bar. I've gone over it about three different times with gas leak detector spray in all the spots you show in the video. I can't find the leak. I know I left the rifle on about 150 bar stored, so I expect that's what's caused this. I never adjust the settings except I turned the power wheel down and back up once or twice. I am left wondering about immersing the rifle in a thin oil bath to track the leak, but I am fearful of oil penetration into the gauges. Any suggestions? 🤔🇦🇺

[@Airbuks]

Good video! I wonder what you think about moisture of the air in the system? How a big deal is it for the m3 in terms of causing leakages over time and causing damage to the all te gun parts including metal? How do you fill up your gun? I use a Nomad 2 but the air filters there aren't really good, so when I release the pressure over the screw, after filling the gun, there are water drops all around the release port. Do you have any recommendatios there?

[@Airbuks]

Hi 👋, thx for the support. Moisture is a big deal in my opinion, moisture creates corrosion in your airgun and affects oring which can cause a leak . If you fill with a home compressor you might wanna bleed off the moisture in the fill system during the fill of a bottle a few time during the process as some on board water traps are not big enough when you have humid conditions. You can add a extra moisture filter but make sure your compressor can handle it . Scuba ships mostly have dry air due to there industrial machinery

[@gorangorinajgori5544]

@@Airbuks What do you use for filling up your airguns? I also wonder what is the best way to store my gun since i'm using it only occasionally, then store it for some months before using it again...i'm thinking about to unscrew the bottle to let the the gun dry this way

[@Airbuks]

@@gorangorinajgori5544 I use a Hill compressor with extra moisture filter and I run it in the house when I fill my bottles to get dry air . Also every cooldown cycle I bleed de line just a second to get some more moisture out of the filter 😉 To store it , I have several airguns and sometimes don’t use some of them for a long time and I always store the filled with pressure in them to make sure the orings stay sealed. If you would take all the air out and leave it like that for a long time you might risk that the orings don’t seat properly anymore and you have a leak . I store them in the case in the house where the temp is stabile and moisture is low ,I also put 1 of those bigger silica bags inside de case aswel to catch any moisture that might be in the foam of the case itself from being out and about .

The name is Soudal and used for gas burners , high pressure air systems etc

[@jeremyarnold1979]

You missed the allen head screw right above the 1st regulator guage #91 #92 #93. mine is leaking there and its a brand new gun thats not 6 months old.

[@Jeeper1378]

Still leaking air. Loosing about 30 bar in 24 hrs. Super slow which is probably why i cant find it. Been over the gun like 5 times with leak spray. Dont think such a small leak will puff a balloon on the muzzle?

[@Airbuks]

You might wanna check the regulator breathing holes . That’s where my slow leak was

[@Jeeper1378]

it was the bottle pressure gauge .. the x ring. Should of known because it had sprang a massive leak before and i thought the ring was broken but it was just pinched and/or over tightened from the factory. Removed/inspected, greased and put back together and all seemed well. The leak detector spray i have only Worked for a second after sprayed on. Meaning it would form a bubble, pop and that was it. I then took a swab and when i sat the swab soaked with LD spray over the area it continually bubbled. Thanks for your help.

[@Airbuks]

@@Jeeper1378 glad you have sorted it out 👊

[@bendang8848]

I wish you also has some time for Avenger .177 Airgun solving the same problem.

[@Airbuks]

I don’t have a avenger and I don’t know the gun in and outside like the M3

[@MrBHuntingDownUnder]

Great video, thanks. oh and "So please stop putting your guns into water" the line I bet you never thought you'd be telling people :)

No indeed , I have seen some posts people doing this and end up having more problems later on 🫣 why ??

[@tranminhtinh8110]

Please let me ask. I want to replace the Humar hammer spring and ti spring for my M3, are they suitable? Thank you.

[@Airbuks]

If you ask if you can replace the hammer and spring with a Huma air one , yes 👍

[@andrewmurray9912]

Hi I dont have a leak, but the opposite sort of, i cant get any pressure into the plenum on my impact m3, ive adjusted the second reg from fully in to leaking when out but no readings on either of rear gauges, cocking doesnt put air through, sorry to jump on your leak video comments but im stuck.

[@Airbuks]

No worries mate , I sounds like you have a blockage in you regulator

[@Art-of-hunt-Mohamed-Gamal]

Unique as usual 👌

[@Airbuks]

Thx 🙏

[@Shootingintheshires91]

I have air coming from my D70 grub screw. Do I just replace the screw or should I be replacing O rings somewhere?

[@Airbuks]

That is the plug to block the air passage for the angled manometer mount . 2 things could fix it . Just tighten it a little more or put a rubber ball or piece of oring underneath it

[@recklessjunkie]

How do you measure scope height if you’ve got a saber tactical trs mounted to the rifle I can measure barrel and scope but the distance between the scope and barrel is what’s giving me issues how did you do this thanks

[@Airbuks]

You can measure it but slightly different. Measure the height of the cocking block an divided by 2 , then measure the height from the bottom of the backbone plate to the bottom of your scope . Add the 2 measurements together and add the half of your scope tube size to it . That should give you a good enough measurement to use in your ballistic app

[@chefrenty9155]

Weer een super interessante video en erg leerzaam, zoals altijd. Is er of heeft u misschien een lijst van meest voorkomende o-ringen die het meest moeten worden vervangen c.q. problemen geven? Dan kan je ze op voorhand bestellen en gebruiken, indien nodig. Ik las op een ander KZbin-kanaal dat FX voor de USA een aparte rivisieset van o-ringen heeft samengesteld. Of is dat hier ook al misschien? Bij voorbaat bedankt voor uw reactie.

[@Airbuks]

Bedankt voor de steun 👊 idd je kan hier ook revisie sets bestellen per model . Je kan dit bv bij Krale of Huma air . Een lijst heb ik niet maar er staan wel schematische tekeningen op de website van FX met volledige parts lijst 😉

The best thing is to take the bottle adapter out , clean the insides of the regulator and change the orings

[@surreallife777]

Are there any alternatives to the FX impact in terms of lower cost?

[@mohameddaher400]

Hello! Thank you so much for the video, I think I got the same leak as you, I changed the O-Ring inside it but I still have a leak... And when I remove the bottle, the air leaks from the reg is this normal ? Please advise I'm going nuts

[@Airbuks]

That front regulator is fragile indeed . Before you do anything else try to put a drop of silicone olie on top of the regulator before puttertje bottle on , it might help to seal ever

[@freetommyrobinson]

Hi. What spray are you using on the fx to look for leaks . Many thanks

[@Airbuks]

Hi , I am using Soudal gas detection spray

[@airrifleshooter.516]

I have a leak from the power block up the barrel hole . What do you think it is ? Response much appreciated

[@Airbuks]

Without seeing it my best guess is that it is the valve not closing properly or one of the orings on the inside of the power block

[@airrifleshooter.516]

@@Airbuks I think it's the valve because when I put the air tank on without closing the valve rod with the end caps . It began hissing sound, when I pushed back the valve rod with my finger it decreased the sound, a lot. But not stopped completely. I am waiting for an o ring kit to change them. Thanks for the response. Much appreciated.

I don’t know all the sizes by heart 😉 but there are great schematics on the FX website that have sizes and part numbers

[@Jeeper1378]

Notice mine leaks around the bottle .. when attached. Only a little when its at max but then stops.. almost like theres a over pressure valve.

[@Airbuks]

Take a look at the dowdy seal or the oring in the bottle neck that seals around the bottle adapter

[@Jeeper1378]

@@Airbuks it was the gauge. My bottle did have a small leak still. Wouldn’t of noticed if it wasn’t for the pinched x-ring under the psi gauge.

[@MrLlosent]

Hello, many thanks for your video. I am desperate as I am stuck with my Impact MKII; since 7 days I can't use it. My problem is I can't reach 150Bars into my plenum, I installed the regulator 11washers, regular set up )()()()()() but even opening quite much the set screw I can not reach the 150Bars. Why? If I unscrew more the regulator set screw it vents and blow out all the air of the plenum. Can someone help me? Many thanks.

[@Airbuks]

🤔 that’s annoying. Have you tried stacking them like this (()()()()()

[@MrLlosent]

@@Airbuks yes it is. I will try this configuration and hopefully the regulator works fine again and reach higher pressures. Now only 120Bar on max open set screw position, weird. I checked almost everything. I disassemble the Impact tens of times and always succeeding, now stucked on this. Must be a little stupid mistake I am ignoring. Thanks mate.

[@margaretmacmurray658]

Exactly why I don't and won't own a impact , I stick with my fx royal nice and simple never let's me down , that's my own opinion.

[@Airbuks]

Indeed the Royal is much simpler, but I don’t mind tinkering with the gun . As I mentioned in the video a airgun that can be ( almost) upgraded every time a new version gets released comes with the downside of having many orings , but I am willing to have that over not being able to upgrade

[@margaretmacmurray658]

If you tinker with air guns in the UK 🇬🇧 you end up in court or prison , so an impact is wasted on 12 foot pound limit, and getting a firearms licence is so hard in the UK , that's why I stick to basic royale.

[@Airbuks]

@@margaretmacmurray658 that is a very good reason 👍 the impact isn’t made to be a sub12 in my opinion
