Williams Comfort Products QYRXS28A Torque Wrench Head 7/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXS28A is a 7/8-inch flare nut torque wrench head designed for precision fastening in mechanical and refrigeration service work. Built with a 6-point contact geometry, this head delivers controlled torque application up to 133 foot-pounds, reducing the risk of rounding fasteners on flare nut fittings. The Y-type shank measures 0.560 inches and accepts compatible torque wrench drives. HVAC technicians and refrigeration mechanics rely on this style of fitting head when working with SAE flare connections on refrigerant lines, fuel lines, and hydraulic fittings where controlled torque is critical to a leak-free joint.

This torque wrench head is suited for use in residential and light commercial HVAC service, refrigeration system maintenance, and any application requiring precise torque on 7/8-inch flare nut fittings. It is sold individually and fits into standard torque wrench setups that accept a Y-shank drive configuration. The SAE sizing makes it appropriate for domestic equipment using inch-based flare fittings.
