Horizontal rotalock service valve sized for a 1-1/4 rotalock thread with a 1" sweat connection and a 1/4" SAE gauge 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.

The integral gauge 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" sweat configuration fits the medium-duty range used across commercial condensing units and refrigeration racks.

Common uses: walk-in cooler and freezer condensing units, supermarket refrigeration racks, commercial HVAC compressor service, and reciprocating and scroll compressor replacement. New surplus, available from King Surplus inventory in Del Rio, Texas.
