Cdi Torque TCQJRXSM19A 19 Mm Flare Nut Torque Wrench Head

Product Description

The CDI TORQUE TCQJRXSM19A is a 19 MM flare nut torque wrench head designed for precision fastening in metric applications. It features a 6-point contact geometry and a J-type shank with a 0.425-inch shank diameter, allowing it to mate with compatible torque wrench handles for controlled output up to 60 ft-lb. This head is built for trade professionals who need repeatable torque on flare fittings and tube nuts in HVAC, refrigeration, and plumbing work, where over-tightening can damage sealing surfaces or cause leaks.

This torque wrench head is suited for residential and light commercial service work involving flare nut connections on refrigerant lines, fuel lines, and hydraulic fittings. Its metric 19 MM sizing covers common fitting sizes encountered in HVAC refrigeration systems and imported equipment. The compact head profile measures 3.15 inches in length and 0.55 inches in height, allowing access in tighter spaces than a standard open-end torque wrench.

Key Features

• 19 MM flare nut head for use on tube nuts and flare fittings without rounding
• 6-point contact reduces fastener damage compared to 12-point designs
• J-type shank at 0.425 inches for compatibility with J-shank torque wrench handles
• Maximum torque rating of 60 ft-lb for controlled, repeatable fastening
• Metric measurement type — sized for metric fittings common in imported HVAC and refrigeration equipment
• Lightweight at 0.17 pounds for reduced fatigue during repeated use

Compatibility

Designed for use with J-shank torque wrench handles that accept a 0.425-inch shank. Intended for metric flare nut fastening applications in HVAC, refrigeration, and plumbing service work.

Installation Notes

Installation and use of this torque wrench head should be performed by a qualified HVAC technician, plumber, or mechanical tradesperson. Ensure the torque wrench handle is set to the correct torque value before engaging the fitting, and always approach the target torque gradually. Do not use an extension or cheater bar on the wrench handle, as this will affect torque accuracy. Verify the shank is fully seated in the handle before applying load.
