Service Gauge Port Valves

Service Gauge Port Valves

WARNING: Wear eye protection when opening/servicing the service gauge port valves.

The high-pressure service gauge port valve is located on the tube assembly - condenser to thermostatic expansion valve.

The low pressure service gauge port valve is located on the manifold and tube assembly - A/C compressor.

Service Gauge Port Valves:

The fitting is an integral part of the refrigerant line or component.
- Special couplings are necessary for both the high side and low side service gauge ports.
- A new Schrader-type valve can be installed if the seal leaks.
- Always install the A/C charging valve cap on the service gauge port valves after repairing the refrigerant system.
