Cdi Torque TCQYRXS18A Torque Wrench Head 9/16 Inch Flare Nut

Product Description

The CDI TORQUE TCQYRXS18A is a 9/16 inch flare nut torque wrench head designed for precise fastening in SAE applications. It features a 6-point contact geometry and accepts a Y-type shank with a 0.560 inch shank size, making it compatible with standard torque wrench drive handles that use that shank format. Maximum rated torque is 74 ft-lb, which covers the typical range needed for flare nut fittings found in HVAC refrigerant lines, plumbing connections, and related mechanical assemblies. Licensed HVAC technicians and plumbers reach for this type of head when torquing flare fittings to specification without rounding the fitting's hex. It weighs 0.27 pounds, keeping the overall tool assembly manageable in tight service areas.

This torque wrench head is suited for residential and light commercial HVAC service work where properly torqued flare nut connections are required to prevent refrigerant leaks. It is also used in plumbing and mechanical applications where SAE flare fittings are present. The flare nut profile fully encircles the fitting, distributing load evenly across all 6 points and reducing the risk of rounding soft brass or aluminum fittings during final tightening. Technicians working on copper refrigerant tubing connections, fuel lines, or hydraulic fittings will find this head well-suited to those tasks.

Key Features

• Maximum torque rating of 74 ft-lb
• Lightweight at 0.27 pounds for reduced fatigue in overhead or confined-space work
• SAE measurement type for use with standard inch-based torque specifications

Compatibility

Designed for use with torque wrench handles that accept a Y-type shank with a 0.560 inch shank diameter. Intended for SAE flare nut fastener applications requiring up to 74 ft-lb of torque.

Installation Notes

This torque wrench head should be installed by a qualified HVAC technician or licensed plumber following the torque specifications provided by the fitting or equipment manufacturer. Always de-pressurize and isolate the system before making or breaking flare connections. Confirm the shank is fully seated and locked in the torque wrench handle before applying torque. Do not exceed the 74 ft-lb maximum rated torque of this head.
