A note about mobile A/C service equipment hoses


 

All hoses used with mobile A/C system service equipment must be equipped with shut-off valves.

The shut-off valves may be either manual or automatic. SAE standards stipulate that the shut-off valves must be located within 12 inches(30 cm) of the “vehicle end” of the service hose, but some equipment manufacturers incorporate the shut-off valve in their quick-couplers.

These automatically shut off the flow of refrigerant when the hoses are disconnected.

Fittings that are unique to individual refrigerants must be permanently attached to the “vehicle end” of service hoses. Adapters for different refrigerants, different systems, or different service port designs may not be attached to service hoses, then removed and replaced with adapters for a different refrigerant.

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
