5/16-24 RH Tube End - 5/8in x .058in

The 5/16-24 RH Tube End - 5/8in x .058in is a precision weld-on threaded fitting engineered for custom cooling system fabrication and high-performance engine builds. Manufactured by MEZIERE, a trusted leader in racing and performance cooling components, this tube end accommodates tubing with a 5/8-inch outer diameter and 0.058-inch wall thickness. Designed for builders, fabricators, and performance enthusiasts who demand leak-free connections and reliable assembly, this right-hand threaded component integrates seamlessly into custom radiator hoses, coolant lines, and bespoke thermal management systems.

Constructed from chromoly steel in its natural finish, the 5/16-24 RH Tube End delivers exceptional durability and corrosion resistance in demanding engine bay environments. The 5/16-24 right-hand female thread provides secure, repeatable fastening for male-threaded fittings and adapters commonly found in performance cooling systems. The weld-on design allows direct attachment to tubing through TIG or MIG welding, eliminating the need for compression fittings and ensuring a permanent, vibration-resistant joint. The compact 1.2 x 0.8 x 3.05-inch footprint and minimal 0.04-pound weight make it ideal for space-constrained engine compartments where every ounce and inch matters.

This tube end is essential for custom radiator hose routing, race car coolant system fabrication, and prototype engine development where OEM hose assemblies do not fit design specifications. Fabricators and engine builders benefit from the ability to create custom-length cooling lines with factory-quality threads at each end, reducing system complexity and improving serviceability. Installation requires welding equipment and basic metalworking skills; the chromoly material welds cleanly and maintains thread integrity under thermal cycling and high-pressure conditions typical of forced-induction and racing applications. Each unit ships individually, allowing builders to source matched pairs or sets for multi-point cooling system designs.
