Williams Comfort Products QJRXSM17A Torque Wrench Head 17MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJRXSM17A is a 17 MM flare nut torque wrench head designed for precise fastening in metric applications. It features a 6-point contact design and accepts a J-type shank measuring 0.425 inches, making it compatible with standard torque wrench drives used in HVAC, plumbing, and mechanical service work. The head handles a maximum torque of 60 ft-lb, giving technicians a reliable upper limit for flare nut connections. This is a single-piece accessory head sold individually and intended for professional trade use where accurate torque application on metric fittings is required.

This torque wrench head is suited for residential and light commercial service work involving metric flare nut connections. Typical applications include refrigerant line fittings, hydraulic connections, and fuel line service where over-tightening must be avoided. HVAC technicians and mechanical tradespeople working with metric tubing and fittings will find this head useful when a calibrated torque wrench is required for code-compliant or manufacturer-specified torque values. It is sold as an individual head unit for use with a compatible J-type shank torque wrench handle.
