Apex Tool Supply AB-9051116 Pressure Reducer Replacement for Stanley Bostitch, Husky, Air Compressors

This valve looks just like the one that came on the Bostich CWC200ST. I used a brush-on sealant to avoid the possibility of cracking it while tightening up things. It works well and a lot cheaper than the expensive and hard to locate OEM. Time will tell how it holds up but so far so good.

Functioed well

Used for my 2 gallon craftsman's air compressor. Great fit

Fit and works perfectly. So far holds pressure as set. Quality seems good too. Also has + and - markings on regulator knoɓ so you know which way to turn to adjust pressure unlike the original.

Like some others mention, some might be able to just use the valve and knob instead of replacing the whole valve and body assembly. The Bostitch compressor I needed it for, has the full cover, which makes it hard to get a socket or a wrench on the valve section alone. I watched one video, of a temporary repair tapping out for a 3/8 bolt. This knob here on this brand, can spin all the way out, whereas the older one, had a clip inside so you couldn't so easily. I had to use a punch to drive it out. I had drilled the hole for the 3/8 bolt too large and than tried the 1/8th male pipe thread I than used a 1/8th drain cock, such as those used on the drain for the compressor tank or a radiator. But I did tap a little to far and the threads weren't as tight as they could have been. A thread locker would also be useful. The range of the valve might not close the regulator all the way as this one is still 40 at the stop. But it did open it to the 140 lbs. The drain cock is a left hand thread, so it works the opposite of the original. I plan on using this assembly on a compressor the doesn't have a regulator.

A quick fix for my broken valve on California Air tools 5510A

I guess the moral of the story is you get what you pay for. This is basically a cheaper copy of the stock one on my Senco compressor that was leaking. Pay attention to the guys talking about the body cracking if you try to fully tighten it. The pipe threads are tapped too deeply, so it never really gets tight, and if you run it all the way on it will bottom out and crack the body. The threads for the gauge and air chuck aren't really tapped deeply enough. They go tight after 2-3 turns. So I broke it on install, and it leaked. The only reason it wasn't a total loss was that it was a good enough copy of the one I was replacing that I was able to take the seal out of this one and install it into my leaking one and I ended up with a mutt regulator that works and doesn't leak. Basically I way overpaid for an o-ring and some spare parts, but the compressor is fixed, so good enough. If I had it to do over again I'd just spend the money to get a correct Senco replacement, or just go match up the leaking o-ring at the local hardware store and replace just that. However, I needed the compressor fixed ASAP and I was able to do that, and as my tools are my livelihood I can't say it was a total waste, just that hindsight as always is 20/20.

Easy to install
