Also Chris, talk about the dead head plug for those who do not have the tank pressure gauge. With the dead head plug you can charge the line and the big fill reg will tell you what u gots left in the tank. Good vid my friend.

Hi, thank you for the info, great video, small question i have is how should you keep a tank if you dont use it for a couple months, should you keep it empty of is it fine if it has some pressure or even if it is full? thank you and keep up the good work

[@johnprior3802]

Great video. I have a Weirauch HW44 pcp . You mentioned in your video that the diving cylinder pressure should be equal to the gun tank pressure. I find that on filling the cylinder pressure reaches the prescribed max fill pressure and leaves the pistol gauge short ie 200 to 170. Is this normal? Should I use the pistol gauge and fill to its max prescribed pressure? Thank you

[@atmodude]

Great video thank you! What's the minimum the tank lay have before we need to refill? I have fx impact m3

[@hunterpangkal7179]

Great, thanks for the information ... when can I have a gun like that

[@usernamemykel]

Excellent presentation in all respects, thank you! Question: I've read that if the rifle has been de-gassed, before adding air, one must cock the gun, receiver open, to allow an air valve to close, so as not to lose air as you try to pump it in. Something that relates to the hammer spring/hammer tension - would you please clarify that?

[@ceterfo]

So I have a question to that question. What do people mean by cocked am I supposed to do just the backstroke or back and forth I don't want to break this thing and all I have is a hand pump.

Hi, thank you for yor video. I use a compressor to fill the pcp but in the end when I try to bleed the line if I do it slowly the rifle's valve won't shut. If I do it rapidly the check valve of the compressor goes bad. What can I do to prevent this? Thank you.

[@stonecold2653]

Hi After building Two filling stations, id like to ask a technical question regarding filling of a PCP rifle. I can fill my rifle with my Nomad II compressor and foot pump no problem but when i go to use my newly built filling station tanks , my rifle will not begin to fill. When i open the valve on my filling station the air is leaving it down the air filling line. The filling stations are rated at 3000 ps (207 Bar). My Rifle will take up to 3000 psi. Is a pressure valve not opening on the rifle because of not enough back pressure? Do i need to have a tank with a higher pressure? Hope you can help ,cheers Red

[@robm5823]

can you make a video or direct me to one that you have made of what exactly we need to use the tank on the rifle such, size, name, of every component that we need to buy and different connector to the rifle i seen some with a small compressor connection on it.

Would like to see videos on cleaning. I've heard it's important where you get your bottles filled do to moisture, is one pave better than another? Dive shop, passing ball, etc.

[@caseG80]

When filling a tank at home you use a filter or two between the compressor and tank both portable tank like here in video or tank on the gun. I didn’t fill any bottles at scuba shops because I was denied the service for not having an up to date scuba license so I just purchased the yong heng compressor there like 240$ from Walmart who exclusively sales them plus 40$ for a 3 -4 yr warranty after watching some KZbin videos using high grade oil other then one simple O ring change it’s been awesome for my needs no trips no hassle are they open how’s Traffic it’s paid for itself after a few of those headaches plus gas prices in Southern California suck But scuba shops have to be using a filter of some sort because obviously people are breathing off the tanks. I’ve never had any issues with tons of water being in my filters and I check them after each fill and leave them open for a few hours just in case of any moisture. There’s many compressors that look like the yung heng that might work but from my research you want to make sure you get a real one because that’s the one tons of people are using in the pcp world.

[@chipsammich2078]

@@caseG80 you don't get the water from the compressor and no matter what filter you use it prolly won't stop it.. Its usually always caused by condensation from temp differences in the air and bottle..

What do you suggest for a compressor? I’m in the market for my first FX gun. I do have a dive shop right down the street but it seems like the tank is almost $800 and it seems like compressors are a lot cheaper and if the dive tank goes out of business, I am screwed so I think I’d like to get a compressor. What would you suggest. Great video. Thank you so much. Fred

[@michaelferris2734]

Excellent video thanks. Please do a video explaining the regulator, how does it work, how to set it for different purposes. It will be very useful for us newcomers on pcps. My rifle FX Dreamline Power Pup, 25 cal. From Costa Rica, thanks again.

[@Hobby_Electric]

The regulator should not be touched to much,it could damage the seal from the dreamline. It maintain a constant speed of the pellets to increase the presicion. Also it limits the Pressure for the high speed valve,to high pressure can damage it also or the hammer cant open it anymore. Low Regulator Pressure = Slow Pellets but more Shots per bottle fill. The Air consuption is not linear, so double pressure is not double Speed or Energy.

[@michaelferris2734]

Thank you for your response, very useful. I’ll leave the regulator alone.

[@brucemarriott2028]

When filling a PCP rifle air cylinder (or any air cylinder) the proper fill rate is vital to the safety of the operator and equipment. According to FAMA Body Subcommittee, "The fill station will usually (but not always) have an Air Control Panel to control the cylinder fill rate which should not exceed 1,500 psi per minute or 113 BAR per minute (which is the highest rate recommended by the major SCBA cylinder manufacturers). Sure, you can slam it in faster, but it's not advisable.

[@Hobby_Electric]

Do you mean the big portable air tank or the air tank inside the gun ? It would almost be impssibile to fill the rifle tank that slow.

[@danielfmontero]

Excelent Thank you

Manufacturers normally use glycerine. It's quite thick, and thus keeps the needle from sudden movements and "bouncing". Hope this helps.

Hey you got a link to a good buddy bottle All in one Tank and fill station

[@SlicerJen]

I know it's 3 years old, but when you said both gauges will go up the same time, i would have added the reason why. What you are doing is opening a low pressure tank to a high pressure tank, so that both tanks will arrive at the same pressure, or attempt to do so. If you have a 5k tank and another tank that can get up to 5k, fully opening the valve will make them both equal, sharing the pressure and thus both be less than 5k, maybe 2.5k each if they are the exact same, with some slop in the line, not sure on the math. So yes, you are stopping the equalizing process midstream by shutting the valve at the 250 bar point since big tank can overpressure the little tank. I point that out because the gauge jumped up pretty fast, even when you were trying to ease it into 250.

[@chuk90]

If I shoot the overfilling air without pellets, wouldnt it damage in internal of the gun?

[@pepesantoraton9865]

[@Videos-io3ll]

Found out, by trial and error, my Brocock air rifle needs to be uncocked to stay filled with air. If I cock it before filling, the air will leak out. This is not stated in the Brocock manual that came with either of my Brocock air guns. I think that this kind of information should be included in all air gun manuals and any video on filling your air gun.

does the air need to be filtered?

Here in Florida, the law now says that dive shops cannot fill your scuba tank to ANY pressure, unless you possess a PADI (dive) certification. I could not get my tank filled yesterday.

Yep ran into this problem in Southern California as well

I had my tank filled today in south Florida at a dive shop. The owner says that he has a lot of PCP customers, including a customer who hunts invasive Iguanas every day! No PADI certificate of Dunkin Donuts discount coupon needed. He only checked the inspection date on the tank. I think that your scuba guy just wants you to pay for expensive diving lessons, to get your PADI certificate. Why don't you RESEARCH the Florida laws???

FYI- The 2021 Florida Statutes Title XXIX Chapter 381, 381.895 "Standards for compressed air used for recreational diving" has 1. No mention of compressed air use by persons engaged in activities other than recreational diving and 2. Makes no mention of any requirement for any purchaser of compressed air to have a PADI certificate. Now show to me, specifically what "law" you are referring to, please.

You'll still be able to use a PCP compressor for aluminum bottle, more airgunner just prefer carbon bottle because it's lighter and upgrades to bigger bottles to hold more air equals to more shot's. Kinda like the umarex gauntlet 2 it's got a heavy aluminum bottle so we'll upgrade it to keep the weight down
