This is simply a valve to hold a vacuum and this little check valve is perfect for that project. There are YouTube videos on moving the vacuum reservoir to a more accessible place and this little check valve is perfect for that project. This will prevent the vacuum air from being sucked in the opposite side.

The plastic gets brittle and any stress from pulling lines will break the nipples off, this is an immediate fix, your welcome, and oh well up by the firewall in the corner by the AC evaporator you should hear a loud hiss from the area.

Why We Like This:
  • Prevented grinding of hubs during hill climbing
  • Easy install if your tubing connections are still in good shape
  • Delivers what they promise

Best Runner up: Dorman Air conditioner check Valve

It has a tried-and-true actual shrader valve that works flawlessly. It will replace the standard "ford/gm ball and spring" oem srvice port, with an improved schrader valve fitting. The core of this valve is the same size / type as the one used in the low side valve, so the removal tool works perfectly on both valves.

This service port is designed to be installed and removed using an unusual 8-sided socket made specifically for standard R134A high-side service ports. The valve has flats around the outside so you should be able to use a socket or wrench to install it. It does require a complete opening up of the ac system, which does require evacuation. It should fit any GM vehicle with r134a refrigerant.

Why We Like This:
  • Great replacement for crappy gm design
  • Perfect fit and a must when servicing your a/c
  • New and hot release
