Williams Comfort Products QYRX18A Torque Wrench Head 9/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS QYRX18A is a 9/16 inch flare nut torque wrench head designed for precise torque application on SAE flare fittings. The head features a 12-point design and accepts a 0.560 inch Y-type shank, allowing it to couple with compatible torque wrench handles. Maximum torque capacity is 67 ft-lb. This head is used by HVAC technicians, plumbers, and pipefitters who need controlled torque when tightening flare nut connections to prevent over-tightening, leaks, or fitting damage. The flare nut profile fully engages the nut on five sides, reducing rounding risk on soft fittings.

This torque wrench head is suited for residential and light commercial refrigerant line, fuel gas, or hydraulic flare fitting work where a specific torque value must be reached and confirmed. It is particularly useful when working in confined spaces where a standard combination wrench cannot provide torque feedback. The 9/16 inch size covers a range of common SAE flare nut applications across refrigeration, HVAC, and plumbing service work. Technicians install it on a compatible Y-shank torque wrench handle to complete the assembly.

Installation Notes

This torque wrench head is installed by HVAC technicians, plumbers, and pipefitters as part of a torque wrench handle and head assembly. Before working on any refrigerant, gas, or fluid line, isolate and depressurize the system according to applicable codes and manufacturer procedures. Confirm the shank size and type on your torque wrench handle matches the 0.560 inch Y-type shank before use. Do not exceed the 67 ft-lb maximum torque rating to avoid fitting or tool damage.
