scope:

This SAE Standard covers fittings intended for connecting service hoses, per SAE J2196, from Mobile Air-Conditioning Systems to service equipment such as manifold gauges, vacuum pumps and air conditioning charging, recovery and recycling equipment.

Due to similarities between English and metric thread sizes a single, unique ACME thread fitting is specified. This fitting was recommended by the Compressed Gas Association (CGA), Connection Standards Committee Task Force as one which could be qualified to meet their requirements for use and safety in a time frame consistent with the introduction of R-134a. It was selected because its unique design would reduce the likelihood of cross-treading service hoses on R-12/R-134a refrigerant storage containers and service equipment.

The high low pressure hose in SAE J2196 requires the charge coupling (used to connect service hoses to vehicle access ports) to be an integral part of the hose assembly. To allow removal of the hose from the coupling for hose replacement only, a two-piece construction with a wrench tight connection is permitted. Specifications covering this fitting are provided.
