Williams Comfort Products QYRX28A Torque Wrench Head 7/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS QYRX28A is a 7/8-inch flare nut torque wrench head designed for precise fastening in refrigeration, HVAC, and plumbing applications where accurate torque control is critical. Built with a 12-point contact geometry and a Y-type shank measuring 0.560 inches, this head accepts standard torque wrench drives and delivers a maximum torque rating of 133 ft-lb. It is sold as an individual head, intended for use with a compatible torque wrench handle. HVAC technicians and refrigeration mechanics reach for flare nut heads when working on SAE flare fittings, where a standard open-end wrench risks rounding the fitting under load.

This torque wrench head is suited for service and installation work on SAE flare connections commonly found in residential and light commercial refrigerant lines, copper tubing assemblies, and related plumbing connections. The flare nut profile wraps around the fitting on five sides, reducing the chance of slipping under high-torque conditions. It is a practical addition to a refrigeration or HVAC service kit where repeatable, code-compliant torque values are required on flare fittings.

Installation Notes

Installation of this torque wrench head is typically performed by licensed HVAC technicians or refrigeration mechanics working on refrigerant line flare connections. Before use, ensure the refrigerant system is recovered and depressurized per EPA Section 608 requirements. Confirm the shank size of your torque wrench handle matches the 0.560-inch Y-type shank on this head before applying torque. Do not exceed the 133 ft-lb maximum torque rating of this head.
