Williams Comfort Products QYRXSM19A Flare Nut Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXSM19A is a 19 MM flare nut torque wrench head designed for precision fastening applications in trade and industrial service work. This head accepts a Y-type shank measuring 0.560 inches and delivers up to 104 ft-lb of maximum torque through a 6-point contact design. The 6-point geometry distributes load evenly across fastener flats, reducing the risk of rounding on high-torque connections. It is sold as an individual head and is intended for use with compatible torque wrench handles by mechanics, HVAC technicians, plumbers, and other trade professionals who require metric fastening capability.

This torque wrench head is suited for residential and commercial service applications where metric flare nut fittings must be torqued to specification. Common install scenarios include refrigerant line connections, hydraulic fittings, and fuel line fittings where over-tightening or under-tightening can cause leaks or component damage. The flare nut head design wraps around the fitting before engagement, making it practical for use in tight spaces where a standard open-end wrench would slip or lack torque control.

Key Features

• 19 MM flare nut head for metric fastening applications

Compatibility

Designed for use with torque wrench handles that accept a Y-type shank with a 0.560-inch drive. Intended as a precision torque head for 19 MM metric flare nut fittings in trade service applications.

Installation Notes

This torque wrench head is installed and used by licensed HVAC technicians, plumbers, and mechanics working with metric flare nut fittings. Always verify that the torque wrench handle is rated to accept the Y-type shank before use. Ensure the system or component being fastened is depressurized and de-energized before beginning torque procedures. Do not exceed the 104 ft-lb maximum torque rating of this head.
