Horizontal rotalock service valve with a 1-1/4-12 rotalock thread, 1-1/8" sweat (ODF) connection, and a 1/4" service port, on a 1-1/8" square body. 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.

The 1/4" service port accepts a schrader fitting or hose for pressure readings and charging without opening the main refrigerant line. The 1-1/4 rotalock with 1-1/8 sweat configuration is common across commercial condensing units and refrigeration racks.

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