Williams Comfort Products QYRXS30A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXS30A is a flare nut torque wrench head designed for precise fastening in SAE applications. Built with a 6-point contact geometry, this wrench head delivers controlled torque up to 146 ft-lb without rounding fastener flats. The 15/16-inch opening fits standard SAE flare nut fittings commonly found in HVAC refrigerant lines, fuel systems, and hydraulic connections. The Y-type shank measures 0.560 inches in diameter, providing a positive drive fit into compatible torque wrench handles. HVAC technicians, plumbers, and mechanical contractors use this tool when fitting or servicing flared tubing connections that require a verified torque value.

This wrench head is suited for residential and light commercial service work involving flare fittings on copper or steel tubing. Typical applications include refrigerant line sets, brake lines, and hydraulic or fuel supply connections where over-tightening risks cracking a flare seat. The 6-point design concentrates force evenly across the nut, reducing slip during high-torque operations. At 0.29 pounds and 4.1 inches in length, it is compact enough for tight mechanical spaces.

Installation Notes

This torque wrench head is installed by qualified mechanics, HVAC technicians, or plumbers during fitting or service of flared tubing connections. Before use, ensure the wrench handle is set to the required torque value per the system manufacturer's specification. Verify the shank seats fully and securely in the wrench handle before applying load. Do not exceed the rated 146 ft-lb maximum torque to avoid tool or fitting damage.
