Williams Comfort Products QYRX40A Flare Nut Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYRX40A is a flare nut torque wrench head designed for precision fastening in HVAC, plumbing, and mechanical service applications. This 12-point head accepts a Y-type shank measuring 0.560 inches and handles a maximum torque of 160 foot-pounds. At 1.25 inches, the flare nut profile wraps around fittings to reduce the risk of rounding corners on soft metal nuts, making it well suited for refrigerant line connections, fuel lines, and hydraulic fittings. Licensed HVAC technicians, plumbers, and pipefitters rely on this head type when torque accuracy and fitting protection are both required.

This wrench head is intended for use in residential and light commercial service environments where flare fittings must be tightened to specification without damaging the nut. Typical applications include refrigerant line set connections, gas supply fittings, and hydraulic or fuel system service. The SAE sizing makes it compatible with standard inch-based fittings commonly found in North American HVAC and plumbing systems. It is sold individually and pairs with a compatible Y-shank torque wrench handle.

Installation Notes

Installation and service should be performed by a qualified technician following applicable codes such as IFGC or manufacturer torque guidelines for the specific fitting type. Shut off all gas, refrigerant, or fluid supply and relieve system pressure before loosening or tightening any fittings. Ensure the wrench head is fully seated on the fitting before applying torque to avoid slippage or fitting damage. Do not exceed the rated maximum torque of the head or the handle.
