Williams Comfort Products QYRXSM18A Torque Wrench Head 18MM

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXSM18A is an 18MM flare nut torque wrench head designed for precise torque application on metric fasteners in professional trade settings. Built with a 6-point contact design, this head fits onto a Y-type shank measuring 0.560 inches and delivers a maximum torque output of 94 ft-lb. It is used with compatible torque wrench handles to tighten flare nut fittings accurately, helping technicians meet torque specifications without rounding fastener flats. HVAC technicians, plumbers, and mechanical contractors rely on this type of head when working on tubing connections, fittings, and threaded metric components where controlled torque is required.

This torque wrench head is suited for residential and commercial service work involving metric flare nut fittings. It is commonly used during installation or service of refrigerant line connections, hydraulic fittings, and fuel or fluid line assemblies where an 18MM metric fastener is present. The flare nut profile wraps around the fitting for improved grip, reducing the risk of fastener damage during torque application. Sold individually, it is a single-unit accessory intended for use with a matching torque wrench handle.

Installation Notes

This torque wrench head is installed and used by licensed HVAC technicians, plumbers, and mechanical contractors.
