Thank you SO much for this video. the spring and flange of the screw out part of the regulator came flying out when i screwed out the cap too far. could not figure out the order to put them back in. the o-ring is missing, but that looks a standard size, so i may have one around. But it still works - thank you, thank you!
We really like the idea of repairing a problem by cleaning a dirty part, rather than buying another part. Cleaning a machine part as simple as this is what everyone should know how to do. A salute to you for making this video, which explains exactly how a pressure regulator works-- few other videos do. We gave this a thumbs UP, and subscribed.
Thanks man! I had just removed mine and ordered the new pressure regulator from Home Depot (my compressor is identical to yours, but the Home Depot house brand--Husky), but after watching your video, I checked and sure enough the replacement part was backwards. Very easy to disassemble, clean, oil, and re-assemble. Looks like originally grease was used for the piston cylinder, which had dried out. I used 3-in-1 oil. Not sure how long it'll last, but at least I know I can redo it again in about a half hour, if needed.
This is an excellent video to repair most regulators are similar and get that calcium deposit out that stops these items from working. I used a sand paper to help get it out.
It worked for me. All the regulator needed was a good cleaning; the gummy deposit at the bottom of the valve prevented the small plunger from seating properly. One small saving, one giant step to reduce waste. Thanks for the excellent video.
Gratitude and Well done. Explanation was so good I can do my Hitachi regulator with total confidence. Hitachi seems to have poorly Thread locked mine onto the compressor. I scraped it all off but do you think Teflon tape is the better way to go? I can do either. Thanks
I just use tape on all connections, never had an issue. The stuff from manufacturers should be a thread sealant like Locktite 545. It shouldn’t be a locker like Loctite 243(medium strength).
Anthony, mine was slightly different design , the inner valve screwed out thru the back, but was like your's corroded, cleaned it and light lube on o-ring and works like new....THANKS!
The direction of the valve is the same . There are 2 outlets for the Gauge one has a plug in it and the other has the gauge in it . just unscrew the plug and the gauge and which places and it will look like the one you have that's leaking . The o rings lose there sizing and thats why you hear air . Put a few wraps of white teflon tape under where the o ring goes this expands the o-ring to stop the leaking . Some regulators have groves the oring fits into . This makes it a lot better and easier to put the teflon tape into . you just cut the tape to the size of the grove and run a few layers of tape around the grove and replace the o ring . The tape under it makes the o-ring bigger and presses the o-ring against the surface and no more leaking . Some people use glide dental floss and it will work but I like the white or yellow teflon tape better .
How did you put a few wrap of white Teflon tape on which o ring ? because regulator have 2 o ring 1 big 1 small.did you wrap Teflon tape on around o ring or outside the o ring? Any way the Teflon tape No glue stick. Thank you
Thanks for such a great video! I have a different problem. The regulator is at zero, if I rotate it for a higher pressure, the knob would just pop up on its own. I can rotate it while pushing it down watching the gauge goes up, but once I stop pushing down, it pops up again and the pressure goes to zero. Where do you think the problem is?
Sounds like the thread maybe stripped. If the cap pops up it is essentially lowering the spring pressure being applied to the valve, causing it not to open. Tried taking it apart yet?
@@TheVintageEngineer Thanks for the reply. I tried to take the knob off but I couldn't. I guess I will need to get the whole regulator off. Maybe I need to change it? I just not feel good going out with all the social distancing thing. I will try to take it a apart and see what is there.
Thank you for your good video. Prior to finding your video, I had problems with my hose/line pressure disappearing after just a few moments of high pressure air flow. This was a progressive problem that kept worsening. I took my regulator apart (not knowing what to look for or what to do), and it looked fine inside. After watching your video, I took my regulator completely apart, as in your video, and still didn't notice anything. However, I did wipe it out/cleaned it, oiled it, and put it back together. It sounded like it was functioning differently after I re-pressurized the tank and line. However, I was then not getting any air flow out my hose. I did notice that the quick coupler/disconnect wasn't releasing/functioning like the other couplers attached to my regulator. I replaced the coupler, re-pressurized everything, and voile - all's well. Thank you. I think the problem was two-fold, sticking plunger valve inside the regulator, and faulty disconnect. I'm happy again. Thank you. I use my cheepy Chinese, garage sale-find air compressor every day, mostly just for cleaning - blowing dirt out of and off of garage sale purchases. I watched other videos relating to this problem, but yours was the best. Thank you for making such a necessary video - and I didn't needlessly purchase an expensive, new regulator!!!
