3/8-24 RH Tube End - 3/4in x .058in

The 3/8-24 RH Tube End from MEZIERE is a precision weld-on fitting engineered for custom cooling system fabrication in high-performance and modified vehicles. This right-hand threaded component serves as a termination point for aluminum or steel tubing in radiator hose assemblies, transmission cooler lines, and custom water circulation systems. Whether you're building a custom cooling loop for an engine swap, upgrading your transmission cooling capacity, or designing a bespoke radiator configuration, this tube end delivers the reliable thread-to-tube connection that professional-grade systems demand.

Manufactured to MEZIERE's OEM specifications, the 3/8-24 RH Tube End features a 3/4-inch outer diameter tubing interface with a 0.058-inch wall thickness rating, making it compatible with standard billet aluminum and steel tube stocks used in street and race applications. The right-hand (RH) thread orientation ensures counterclockwise tightening, the industry standard for cooling circuit fittings. This compact weld-on design—measuring 1.15 x 1.15 x 3.85 inches and weighing just 0.07 lbs—minimizes packaging constraints while maintaining structural integrity under pressure cycling, vibration, and thermal expansion cycles inherent to high-output engine bays.

Mechanics and fabricators building custom cooling systems, late-model engine conversions, and competition vehicles rely on MEZIERE tube ends to create leak-free, field-serviceable connections. Installation requires TIG or MIG welding to your existing tubing; ensure proper heat management during welding to avoid thread damage. This fitting is ideal for enthusiasts upgrading cooling capacity on turbocharged builds, LS swaps, or water-cooled modifications where stock radiator routing won't suffice. Pair with appropriate hose barbs, adapters, and thermostatic valves to complete your custom circuit.
