Horizontal rotalock service valve with a 1-3/4-12 rotalock thread, 1-1/8" sweat (ODF) connection, and a 1/4" service port, on a 1-3/8" square body. Rotalock valves thread onto compressor suction and discharge stubs and liquid receivers, giving a removable, gasket-sealed isolation point for service, evacuation, and compressor changeout in refrigeration and air-conditioning circuits.

The 1/4" service port accepts a schrader fitting or hose for pressure readings and charging without opening the main refrigerant line. The larger 1-3/4 rotalock body suits commercial refrigeration condensing units and larger semi-hermetic compressor service.

Common uses: commercial refrigeration condensing units, walk-in cooler and freezer racks, supermarket refrigeration, and larger semi-hermetic compressor service. Unused, no box: factory bulk-packed and sold individually without a retail box. Available from King Surplus inventory in Del Rio, Texas.
