The 6 Best low pressure AC caps (2023 reviews)

If you are looking to buy a suitable cap for your daily purpose, dorman low pressure ac cap is the right option. 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. It is designed for one time use at the factory and is prone to leak. The system is pressurized. It does require a complete opening up of the ac system, which does require evacuation. The Dorman replacement connector makes much better sense, and works perfectly.

The thread size is M12 x 1.5mm pitch. This is a product designed to replace the OEM part. It is definitely a big improvement over the gm valve that is standard.

Why We Like This:

High side replacement fitting with schrader valve
More leaks and was able to charge the ac to get it cooling again
Perfect fit and a must when servicing your a/c
Replaces the inherantly leaky (schraderless) gm high pressure connecting valve
