The CDI TORQUE TCRTWH44J is a ratcheting flare nut torque wrench head sized at 11/16 inches, designed to attach to compatible torque wrenches via a J-type shank measuring 0.425 inches. It delivers controlled, repeatable torque to flare nut fittings without rounding the fastener — a critical need when working on refrigerant lines, fuel lines, and hydraulic connections. The ratcheting mechanism allows fastener engagement in tight spaces where a full swing is not possible. At 0.52 pounds, the head is compact and lightweight, making it practical for overhead or confined-space work. Licensed HVAC technicians, plumbers, and pipefitters are the typical end users for this type of wrench head.
This torque wrench head is suited for applications where flare nut fittings must be torqued to specification — including refrigerant line connections on HVAC and refrigeration equipment, gas line fittings, and hydraulic line assemblies. The ratcheting flare nut design grips multiple points on the fitting to distribute load and reduce the risk of damage to soft-metal or plated fittings. It is sold as a single head and is intended for use with a compatible J-shank torque wrench handle sold separately.
Designed for use with J-shank torque wrench handles that accept a 0.425 inch J-type drive. No specific compatible handles or system models were identified in the product data — confirm handle shank compatibility before ordering.
Installation and use should be performed by a licensed technician familiar with torque specifications for the fitting type and material being serviced. Ensure the torque wrench handle is rated for the required torque range before attaching this head. Verify the head is fully seated on the shank before applying torque. Do not use impact drivers or pneumatic tools with this wrench head.
