Williams Comfort Products QYRXS20A Torque Wrench Head 5/8 Inch

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXS20A is a flare nut torque wrench head designed for precise fastening of SAE flare fittings in refrigeration, HVAC, and plumbing applications. Built with a 6-point contact design, this 5/8-inch head accepts a Y-type shank with a 0.560-inch shank size. It handles a maximum torque of 74 ft-lb, making it suitable for medium-duty fastening tasks where over-tightening a flare nut connection would risk damaging tubing or fittings. Licensed HVAC technicians and plumbers reach for this type of head when working in tight spaces where a standard open-end wrench cannot deliver controlled, measured torque output.

This torque wrench head is used in residential and light commercial HVAC service, refrigeration line set installations, and plumbing work involving SAE flare connections. It is well-suited for connecting and torquing flare nuts on copper refrigerant lines, gas supply lines, and similar tubing assemblies where manufacturer torque specifications must be met. The flare nut profile fully wraps the fastener hex to reduce the risk of rounding during high-torque application.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with torque specifications for flare fittings. Always de-energize equipment and isolate the refrigerant or gas supply before working on any line connections. Confirm the torque wrench drive and handle are rated to the required torque value before applying load. Do not exceed the 74 ft-lb maximum torque rating of this head.
