3/8-24 LH Tube End - 7/8in x .058in

The 3/8-24 LH Tube End - 7/8in x .058in from MEZIERE is a precision weld-on fitting engineered for custom fluid systems in high-performance automotive and industrial applications. This left-hand threaded tube end connects 7/8-inch diameter tubing with 0.058-inch wall thickness to hydraulic, coolant, or fuel line networks where space constraints or reverse-thread configurations demand a specialized solution. Built for fabricators and custom builders who require reliable, leak-free connections on race cars, hot rods, and specialty vehicles.

Manufactured from chromoly steel and finished in natural (bare) condition, the 3/8-24 LH Tube End delivers durability and strength in demanding environments. The weld-on design allows direct fusion to tubing, eliminating mechanical fasteners at the connection point and reducing assembly complexity. Left-hand threading (LH) reverses the standard clockwise tightening direction, making it ideal for applications where vibration or rotational forces might loosen conventional right-hand fittings. The 3/8-24 thread pitch ensures compatibility with standard metric and fractional line adapters, while the chromoly construction withstands thermal cycling and pressure fluctuations common in racing and high-output systems.

This fitting suits custom tube bending and welding projects where OEM solutions fall short of design or packaging requirements. Installation requires proper welding technique to ensure a sound bead around the tube end shoulder; professional fabricators typically use TIG or MIG processes for optimal results. The natural chromoly finish may require protective coating or primer if exposed to moisture or corrosive environments. Whether you're building a custom cooling system, fuel delivery circuit, or hydraulic control line, the 3/8-24 LH Tube End provides the specialized thread direction and tube compatibility needed for precision fabrication.
