Horizontal rotalock service valve with a 15/16 rotalock thread and a 3/4" sweat (ODF) connection, with a 1/4" service port. Rotalock valves thread onto compressor service ports, 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.

Branded Royal, model 2201A, embossed on the service port cap. The 1/4" service port accepts a schrader fitting or hose for pressure readings and charging without opening the main refrigerant line.

Common uses: residential and light-commercial condensing units, walk-in cooler and freezer service, and small reciprocating and scroll compressor replacement. Unused, no box: factory bulk-packed and sold individually without a retail box. Available from King Surplus inventory in Del Rio, Texas.
