Dude!!!! You just saved me a bunch of money, time and frustration. I have the same compressor, and the leak had gotten progressively worse over the last few months. I was ready to replace the entire manifold, but then I came across this video. I did it just the way you described and now it's holding pressure perfectly. Thank you!

[@moderntouchfurniture]

Wow thanks for posting this, I had no idea how I was going to fix this problem. My wife said staring at this thing and scratching my head over and over was not a good sign. Thank you sir!

[@benharrison5816]

My regulator was still leaking after following this procedure. My guess is maybe the o-ring failed due to forgetting to drain the compressor after use a few times. I've only owned it a few months. Anyway, maybe someone will find this useful, to fix the issue I bought N008792 Regulator Repair Kit (off Amazon, but available elsewhere as well, for about $23). It is for Craftsman, Black and Decker, Porter Cable etc. compressor regulators, but I read a comment from someone that it fit their Husky 33 gal compressor, and yep it fit my 30 gal 200psi perfectly. I just had to replace the plastic disc which had the o-ring on it, and it comes with silicone grease. And I have the remaining parts in case any of the other parts of the regulator fail down the road which is nice just in case.

[@psamma21]

Dude, this is a life saver of a comment lol saw that same repair kit on amazon but didnt know if it would fit a husky or not. Definitely going to give it a shot now because my plastic disc broke in half. THANK YOU

[@onecrazywheel]

Thanks a million! This is what YT was made for. I own the same air compressor and have had this issue for months. Great job. Great video! Big Like! God Bless you. Jeff

[@billriser3537]

Thanks for the article. Fixed my Harbor Frt Air Compressor. Got new o'rings & lube from Ace Hardware. Used Emery Cloth to clean the bore. Leak is now fixed.

[@arliefrederick4991]

Thank you very much!! I watched another video showing the exact same issue but your little extra details did the trick. I was going to by a new regulator manifold but not now. Again Thank you

[@SidKreis1]

Thanks! This was bugging me for months. Your fix did it.

[@sncboom2k]

That fixed my Husky compressor right up! Thank you so much!!!

[@SlammedZero]

Awesome video man!!! Mine started doing this and your video was great. Thank you.

[@levonkitapszyan6626]

Thanks Brother . I just fixed the leak on my Husky 33 gallon air compressor watching this video.

[@smittylange4873]

Glad you put this video up. Oring was on backwards for mine. Thank you sir mine is not any more!!!

[@scottdallmeyer4481]

Thanks, I have the exact same compressor with the same issue. Fixed now.

[@jw6353]

Thanks dude.! Haven't had time to look and figure at the leak. Watch your video and went why not let's try it. Mine was a Kobalt little easier to take apart found a broken gasket

[@davidr1809]

Thanks! I had the same issue with my 8 gal. Husky. The knob wouldn't come off at first. It has a brass pin that keeps it from coming off. I was able to back the pin out a bit with a small screwdriver. After that it was easy. Mine had some tiny specks of debris in it. After I reassembled it, the problem was fixed. No more leak.

[@stevesmith7352]

Thanks! Having a hissing issue right at the adjustment valve. I'll give this a try.

[@nestorautorepair]

U are the best I been having the same problem I will give that a try today big thanks boss

[@baileydo7357]

Thanks man , i have same problem with my campbell hausfeld ,repair the same way, saved me headache

[@dtwo82]

Dang, I just ordered a new manifold for about $90 with tax and shipping, then I watched your video and it fixed my problem. Wish I saw it sooner.

[@Syke492]

Loving it!!

[@luckfavorstheprep]

I’m experiencing the same problem with the exact same air compressor. Mine started to leak while increasing the tool pressure with the red knob. I’ll try to clean o-ring and see if that works. Thank you for the video.

[@MarkPryor1]

Thanks for the video. Mine still leaks when I take the seal out. I think there is another oring in there that is leaking. Could be temperature related. I had my compressor in an enclosure and it got pretty hot. It was cycling a lot too.

[@maxheadroom6183]

AWESOME!!

[@NYOB0001]

Thanks!

[@matthewmills6452]

This is for anybody else that may read this in the future with the same type of compressor. Be careful when you unscrew the regulator knob. If your regulator is seized or sticky the parts he is showing to take off can fly across your shop and get lost in the sawdust. Best to bleed the compressor down. You can service a seized regulator by using either a 17mm or 11/16" box wrench from the back side. Remove the needle, spring and o-ring and clean it and lubricate it. Mine had seized and when they do you lose the function to be able to adjust the pressure to the tool. It was a simple fix, but I think I looked everywhere online and couldn't find it.

[@Nevaru_42]

Sadly replacing the o-ring didn't work but I noticed the threads on the Red control knob were damaged, ended up finding a Porter Cable replacement regulator assembly for $32 that fits much better and now I am all fixed up. It has a shorter knob so less chance for it to get banged/damaged now, part number is N246884 just had to re-use the pressure relief valve from the old one as it wasn't included, I used a tee fitting on that side so I would have 1 tank pressure outlet and 1 regulated. Also mine NEVER pumped up to the advertised 175psi tank pressure with the original regulator, it shut off at 150psi, now it works properly with the replaced regulator.

[@Lowkeywav.]

Great video I will double check that for my compressor. I having a issue building pressure passing 50 PSI in the tank. any idea what my issue could be?

[@TheMrmmkkpro]

Great info , i screwed my pressure knob off with some pressure on the tank and the air blew all the guts out . I found everything but i must have another problem. I noticed your pressure didnt do that.

[@VintageSlots]

So I have the same problem. The hissing is not coming from the o ring but rather from the center of that little disk. Is there supposed to be something in the center to prevent the air from coming out? I didn't see any micro o-ring or anything.

[@coreelite]

Does anyone have a link to this rebuild kit? I have this exact compressor and a leaking regulator. Or at least know the size of the O-Ring that needs to be replaced?

[@ronyerke9250]

Actually, that's not an o-ring. The manuals call it a pressure seal. They're used in hydrolic applications, too. Grooved side toward the pressure.

[@vazquez7871]

The Manuel states to drain the air after each use

[@andybub45]

I have the same air compressor and it is leaking near the regulator. I noticed that the leak started when it got cold. I think that it may be due to the cold temperature expanding the aluminum manifold. I see that lots of other people had the same problem. This should be made better especially because its made in the USA! I will try your fix and see if that fixes it.

[@andybub45]

Completed the repair today and it doesnt leak anymore! Thanks for the video! Hopefully I only have to do it once.

[@realtruth97]

The temperature is probably freezing the oil on the O ring seal.

[@scottterry3520]

My red regulator handle seems like it stripped a little, I’ll get so much pressure then it pops and presser drops as I try to turn it, does anyone know if I can just buy the the red turn nob without buying the whole $100.00 regulated.?..

[@roylane8501]

Never mind. That internal pin I mentioned came from something else and was lying right where the srping from the knob landed. It just looked like a part that could have came from the under side of the plastic cup. My plastic cup isn't made the same though. It is designed so the 2 divided dides compress together. No O-Ringin in there. The only O-ring I can find at Husky parts is one that goes inside the plate where the cup meets the actual regulater plunger

[@TheGuccibane]

Where the hell can I buy the damn regulator knob itself? I've looked everywhere. If it's not available, what can I use as a replacement to that red knob with spring?

[@YocahuBagua]

I have the exact same problem. Did you find the regulator knob?

[@scottterry3520]

I need the same thing, haven’t used it much and it’s stripped, terrible design

[@DebDDigger]

No matter how low I turn the regulator knob, the regulator guage keeps going up until I turn the compressor off. I've used it only a few times before without any problem, but it has been a few years. I gave away my older little compressor when I bought my big Husky and now I'm sorry. I don't want to be blowing 150 psi through my tools. Do I need a new regulator?

[@attached2mygarage37]

If adjusting the regulator knob doesn't increase or decrease the pressure to the regulator the threads may be striped on the knob or it's time for a new regulator.

[@matthewmills6452]

It means your regulator is seized. I know you've moved past, so this is for others that may read in the future. Use a 17mm or 11/16" box wrench from the back side of the regulator. Twist out the spring and clean the needle, o-rings, and spring. Put it back in. From the front side, the part he showed to remove in the video, you should be able to push inside and feel the action of properly functioning regulator. The needle will move back and forth smoothly. Many replacement regulators are sold, when this is the problem.

[@stelthcamo357]

My tool side gauge wont even go to 150 with regulator all the way in it only goes to bout 140

[@roylane8501]

Where is the internal pin? That fell out if min

[@maxheadroom6183]

Where can I get this O-Ring? part No.?

[@stelthcamo357]

Go to a hardware store and get o ring #94 I seen a video on here and it's the same size it fixed mine between than buy a 110 dollar regulater

[@Nevaru_42]

Anyone have any idea where to get the replacement oring if it is damaged?

[@crosbyja79]

Mine was damaged as well... haven't had ANY luck finding a replacement so far. And Husky/Home Depot will only sell the entire regulator assembly for $80 or so... We need an 80 cent piece, and they want us to spend $80 to fix... silly

[@duanestonehouse5825]

Harbor freight sells a box with rubber oring and I replaced mine with one on those and works perfect. They are round not flat but worked even used automotive grease on it and in where it goes. Works and slides perfect

[@attached2mygarage37]

Duane Sonehouse...... I support this message. Harbor freight box of o-rings very handy.

[@OGRH]

@@crosbyja79 and the Internet will hide results only pushing corporate interests… and they’re blaming us for using up all of the resources! It’s getting worse and worse!

[@OGRH]

@@duanestonehouse5825 yes sir I fixed a nice Faucet and it works better than when the original O-ring was new… almost as if it was designed to fail. It was the O-ring that worked with the switch for the two different spray patterns… couple hundred dollars saved on an O-ring that likely costed me 15% of one penny.

[@loumaniandevil]

Great video! Turns out my O ring was put in backwards since day one.

[@MrDaedalusWren]

Unfortunately. this video tells you to put the seal in backwards. The seal ring goes in so the lip faces in, NOT out.

[@frankklier2315]

​@@MrDaedalusWrenthanks!

[@bobbyberger9928]

My compressor was doing the same thing...when i did this there was full tank pressure right there snd everything came flying out. I found it all and reassembled and i think it leaks worse

[@stevenstucco]

Haha

[@MrDaedalusWren]

I have repaired this issue countless times and if the seal is not put in lip first, it will leak again. This video is wrong in the orientation of the seal. turn it around.

[@realtruth97]

Your problem is.....you bought an oiless compressor. Smh

[@attached2mygarage37]

Hey if you are willing to donate to the cause, I'd be happy to replace with an oil lubricated compressor...... Just trying to pinch those pennies. Have had this compressor for nearly 4 years now with almost daily use. Still runs like a champ. For a budget compressor, semi portable, and higher than most PSI on 120v I recommend.

[@realtruth97]

@@attached2mygarage37 Point made. We've come across our most important problem now. Money. Money is the reason why people cant live the way they want. This system is based on Money. And money turns people into greedy and selfish beings. The people running the system know this already. They want you to be a slave of money, for the rest of your natural life. They know that this money based system has lived its usefulness. We're at the point in life where we can live in a system without money, based sely on common sense and generosity. In out current system things cant get done unless you got the money. From Government things, to individual things. You cant get anything done unless you got the money. My point is that we need a new system. And I got this system. I already came up with a way to live in paradise. We wont be able to live good unless we get rid of the money limitation. We, as a species are limited by money. We're at the point in life where we can evolve, and become better. But the secret societies that control the system dont want to give up their power. It's Freemasons doing all this. And until we get rid of them and their web of secret societies, we will never be free. So yes, your problem is much bigger then pennies for a new compressor now. We're up against satans army.
