Williams Comfort Products QJRX22A Torque Wrench Head 11/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS QJRX22A is an 11/16-inch flare nut torque wrench head designed for precise fastening of SAE flare fittings in refrigeration, HVAC, and plumbing applications. The head uses a 12-point contact geometry and accepts a J-type shank measuring 0.425 inches. Maximum torque capacity is 60 ft-lb, making it suitable for securing flare nut connections without over-torquing brass or copper fittings. Licensed HVAC technicians and refrigeration mechanics rely on torque wrench heads like this one to meet manufacturer torque specifications on refrigerant line connections and service valves.

This torque wrench head is used in residential and light commercial HVAC service work where flare fittings on refrigerant lines, service ports, or copper tubing must be tightened to a specified torque. It is particularly useful during system commissioning, line set installation, and service calls where proper flare nut seating is critical to leak-free operation. The J-type shank interfaces with compatible torque wrench handles that accept the 0.425-inch J-type drive.

Key Features

• 11/16-inch flare nut head sized for standard SAE refrigerant line fittings
• 12-point contact design for positive grip on flare nuts
• J-type shank at 0.425 inches for compatibility with J-drive torque wrench handles
• Maximum torque rating of 60 ft-lb to prevent over-tightening
• Compact profile at approximately 3.8 inches in length and 0.5 inches in height
• Lightweight at 0.17 pounds for easy single-hand use in tight spaces

Compatibility

Designed for use with torque wrench handles that accept a J-type shank with a 0.425-inch drive. Intended for SAE flare nut applications in HVAC and refrigeration service.

Installation Notes

Installation of this torque wrench head should be performed by a qualified HVAC technician or refrigeration mechanic. Before torquing any refrigerant line flare nut, recover system refrigerant and relieve system pressure in accordance with EPA Section 608 requirements and applicable local codes. Ensure the J-type shank is fully seated in the torque wrench handle before applying load. Do not exceed the 60 ft-lb maximum torque rating to avoid damaging flare seats or fittings.
