Williams Comfort Products QJRXS16A Torque Wrench Head 1/2 in

Product Description

The WILLIAMS COMFORT PRODUCTS QJRXS16A is a 1/2-inch flare nut torque wrench head designed for precise, controlled fastening in applications where over-torquing can damage fittings or connections. Featuring a 6-point contact design and a Type J shank measuring 0.425 inches, this head delivers reliable engagement on SAE flare nut fasteners. It handles a maximum torque of 54 ft-lb, making it well-suited for plumbing, HVAC refrigerant line work, and mechanical assembly tasks where torque control is critical. Licensed tradespeople and experienced mechanics rely on this style of wrench head to protect soft fittings and threaded connections during installation and service.

This torque wrench head is applicable in residential and light commercial service scenarios involving SAE flare nut connections. It is commonly used when connecting refrigerant lines, gas supply fittings, and other flared tubing assemblies where specific torque values must be achieved without damaging the fitting. The 6-point configuration provides better contact distribution across the nut, reducing the risk of rounding. It mounts to compatible torque wrenches via the Type J shank interface.
