7/16-20 RH Tube End - 7/8in x .058in

The 7/16-20 RH Tube End - 7/8in x .058in from MEZIERE is a precision-engineered weld-on fitting designed for custom cooling system fabrication and high-performance automotive applications. This threaded tube end serves as a critical junction point in radiator hose lines, transmission cooler setups, and custom engine bay plumbing where professional-grade reliability is non-negotiable. Built for fabricators, engine builders, and restoration specialists who demand repeatability and durability in their work, this component eliminates the guesswork from tube termination and ensures leak-free, vibration-resistant connections.

Machined from chromoly steel in its natural finish, the 7/16-20 RH Tube End features a right-hand female thread (7/16-20 pitch) that accepts corresponding male hose fittings with precision tolerances. The 7/8-inch tube diameter and 0.058-inch wall thickness specification ensure structural compatibility with standard custom cooling lines while maintaining adequate wall integrity to withstand system pressures and thermal cycling. The weld-on design allows direct fusion to existing tubes or manifolds, creating a permanent, metallurgically sound connection that outperforms compression fittings in high-vibration environments and extreme temperature ranges typical of race vehicles and heavily modified engines.

This fitting is ideal for builders constructing custom radiator systems, remote oil coolers, transmission cooler lines, and specialty plumbing in street rods, drag cars, and performance trucks. The right-hand thread designation ensures compatibility with standard metric and SAE -6 or -8 hose fittings commonly found in aftermarket cooling systems. Installation requires basic welding capability and is best performed before final system assembly; the compact 1.3 x 0.95 x 2.85-inch footprint allows flexible routing in tight engine compartments. Sold individually, allowing builders to purchase exactly the quantity needed for multi-point cooling configurations.
