I needed a replacement air regulator for my Huskey 1.5 gallon air compressor. I bought this one. I unscrewed it and just used the diaphragm part and it fit perfectly. Wow, very happy!!!

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.

The pressure regulator on my air compressor started leaking and let out air from the tank. Looked up the brand and model of compressor but could not find out the make of the regulator. So after looking at regulators on amazon I saw this one and it looked just like what I needed. So took a chance and got it. It was exactly what I needed and all I had to do was unscrew the regulator from the compressor and actually since it was the same all I needed was to unscrew the new regulator from the new junction block and screw it right in on the compressor. It has been working like new ever since !!! Now can regulate the outgoing pressure with no worries of a leak !!!

I used this Apex Tool Supply AB-9051116 Pressure Reducer Replacement for Stanley Bostitch, Husky, Air Compressors for a central pneumatic 1.8 HP 17 gallon 150 PSI. My objective was to replace the regulator knob on the central pneumatic 1.8 HP which I accomplished. What I did was remove just the regulator from pressure reducer assembly, this was the chrome section. You'll need a large crescent wrench, I never determined what size the bolt was, but it was large. I used a vice to take it a part. It was the exact size and the replacement when easy. Compressor works fine.

This was exactly what I needed to fix a 2009 pancake. Works excellently! Thank you for still making these parts for bostitch. I looked on their website and the shipping cost was more than the part. Free shipping with Amazon!
