Telemecanique Sensors 9049A56 Pressure Switch, Release Valve

Perfect replacement for my frankensteined compressor (Campbell Hausfield tank, auxiliary tank, IR PUMP, Century motor). Installation took 10 minutes and no more leaking as of now will update if it starts to leak but as of now 5/5 stars!

It’s doing what it’s supposed to do.

I was elated with this product. My 20 yr old 60 gal Devilbiss air compressor stopped working and found it was do to this broken valve. I had no idea that I could find so quickly and buy thru Amazon for a ridiculously low price and free shipping. I installed it in 10 minutes and works like new, so much so I quickly ordered another one for a spare. Thanks Amazon

it's doing what it's supposed to, unloading the pressure.

This part replaced a fatigued original and got me back up and running quickly.

I didn’t have part numbers in my manual for this switch. Simple remove & replace to keep my old compressor up and running.

Replaced leaking valve on my shop compressor. Worked for a couple weeks and thought the irritation was gone... Nope, this one started to leak. Now after a couple weeks of leaking and messing with it to stop, it leaks constantly. Past return time.

Part is exactly right but it is missing the nut for mounting and the compression nut for air line. Have to purchase other parts for what should have been in package.
