13/16" Square Drive 12 Pt Flare Nut Head, J-Shank - CDI Torque Products

The CDI Torque Products QJRX26A is a specialized 13/16" Square Drive 12-Point Flare Nut Head, J-Shank, engineered for professional technicians. This precision-machined head ensures accurate and repeatable torque application on critical line fittings, particularly in the confined and often obstructed spaces common in heavy-duty automotive and industrial environments. Designed for seamless integration with CDI J-shank torque wrench handles, it provides a solid and reliable connection for maintaining system integrity.

Key Features

• 13/16" Flare Nut Profile: Specifically sized for common larger brake, fuel, hydraulic, and refrigeration line fittings found on medium- and heavy-duty trucks, industrial machinery, and fleet vehicles.
• 12-Point Design: Provides multiple contact surfaces for enhanced grip on the fitting, significantly minimizing the risk of rounding and slippage compared to traditional open-end wrenches, ensuring reliable fastener engagement.
• J-Shank Connection: Facilitates quick and secure attachment to compatible CDI J-shank torque wrench handles, promoting efficient head changes and precise torque transfer. The J-Shank has a 0.425" square drive size.
• Precision-Machined Construction: Manufactured with tight tolerances at both the head and drive, ensuring accurate torque application and reliable fastener engagement with minimal play. This head is constructed with high-quality materials, offering exceptional durability and resistance to wear.
• Optimized Low-Profile Access: Its slim flare nut design allows technicians to effectively access and properly torque fittings in confined areas where standard sockets or box-end wrenches cannot fit due to surrounding components.

Applications

The QJRX26A is an indispensable tool for tightening or verifying torque on 13/16" flare nuts across a range of critical systems, including:

• Heavy-duty and commercial vehicle brake, fuel, and hydraulic systems, ensuring leak prevention and operational safety.
• Fleet maintenance operations on medium- and heavy-truck hydraulic and pneumatic lines.
• Industrial and plant maintenance for fluid, gas, and refrigeration lines where system integrity is paramount.
• HVAC, mechanical, and process systems utilizing 13/16" flare fittings where accurate torque is vital for preventing leaks and maintaining performance.
