Aeroquip FJ3055-06-1012S Female O-Ring Fitting

This Aeroquip FJ3055-06-1012S is a steel female O-ring hose fitting built for refrigerant lines carrying 134A, R12, R22, R502, MP39, MP66 or R404A. It suits technicians servicing automotive or industrial air-conditioning systems that require a dash-12 connection.

7/8-18 Thread and 45-Degree Elbow Compatibility

The fitting features a 7/8-18 female thread and is designed for use with a 45-degree elbow, allowing routing in tight engine bays. Steel construction resists vibration and corrosion, while the O-ring seal helps prevent leaks during pressure cycles.

Rated for 500 PSI Working Pressure

The part carries a maximum working pressure of 500 PSI and a minimum burst pressure of 2000 PSI, meeting SAE J2064. Hose inside diameter is 0.63 in and outside diameter is 0.98 in, so the assembly must match those dimensions for a secure crimp.
