Works like new again !!
I replaced my compressor accumulator orifice tube high pressure sensor low pressure sensor and a new sensor for the back of the compressor new GM Schrader valve and service port/ high side fitting you will need a special socket to change the high side service port. Emptied out the old accumulator into a measuring cup I used my two cycle mixing cup as it gives fluid ounces, added what came out of the old accumulator to the new accumulator. With new peg 150 ACDelco refrigerant oil, Dumped out the refrigerant oil in the new compressor it measured 4 oz replaced refrigerant oil with ACDelco pag 150 oil I did this twice with my 97 Chevy Dually and my 99 Chevy Tahoe both systems work perfectly Ice Cold Air again !!

great price. good oem quality
replaced the high side ac service port on my 2009 hhr ss. this fitting works on a bunch of different cars/trucks/suv. you do not need a specialty socket. i useda 15mm line wrench and held the bottom part thats on the high side ac line with a cresent wrench. ac is a must. happy that its working again

Fits my 2013 Silverado Z71
Fits my 2013 Silverado Z71. This valve is apparently a common leak point. I picked up a socket that was an often purchased together suggestion too. The old one came right out, the new one went right back in. Recharged the system, and it's blowing cold air again. All that trouble for a $6 part. I thought I needed a whole new line, I was very happy to see this was replaceable. Hopefully it lasts 100k miles more.

if your checking high side pressure you will need to keep one of these on hand as they rarely seal properly after removing manifold gauge set. Good price and quality.

Ball valve leaked and cost me a whole second charging.
