The 5 Best AC Valve caps (2023 reviews)

The dorman ac valve cap's material feels more premium than its price would suggest. This is a schrader valve to replace the check valve on the high side service port. It is designed for one time use at the factory and is prone to leak. It does require a complete opening up of the ac system, which does require evacuation. The valve has flats around the outside so you should be able to use a socket or wrench to install it. It is an ideal solution to replace the "ball and spring" high side port.

The thread size is M12 x 1.5mm pitch. This looks like it will last for many uses from the way the Schrader valve in it is made. This is a product designed to replace the OEM part.
