What is the Dorman 800-955?
It's an A/C service valve — a Schrader-style valve that seals the air conditioning refrigerant service port and opens to allow charging or recovery when a service hose is connected.
What are the thread sizes?
Both ends are M12 x 1.50, with one female-thread end and one male-thread end at a straight fitting angle.
How do I know it fits my vehicle?
It's a direct replacement for a broad list of GM applications such as the 1999-2015 Chevrolet Silverado 1500. Check the Buyer's Guide tab to confirm your exact year, make, and model.
What are signs this valve may need replacing?
A worn service valve can let refrigerant seep from the service port, causing a low charge and weak cooling. If the valve is the source of the leak, this replaces it. Diagnose the leak's cause before replacing.
What's included, and does it have a quick-connect fitting?
The package contains one A/C Schrader service valve. It has no quick-connect system, and installation instructions are not included.
