3/4-16 LH Tube End - 1-1/8in x .083in

The 3/4-16 LH Tube End - 1-1/8in x .083in by Meziere is a precision-engineered rod end fitting designed for custom cooling systems, fuel lines, and hydraulic applications in high-performance automotive builds. This left-hand threaded component serves as a critical junction point in race-proven cooling circuits where vibration isolation and leak-free operation are non-negotiable. Whether you're fabricating a custom radiator hose manifold, building a remote oil cooler setup, or routing high-pressure brake lines on a track car, this tube end delivers the durability and reliability that serious engine builders demand.

Manufactured by Meziere—a leader in lightweight aluminum cooling solutions and fluid system components—this tube end features a 3/4-16 left-hand thread specification that prevents accidental loosening under engine vibration and cornering loads. The 1-1/8-inch outer diameter with a .083-inch wall thickness strikes a critical balance between structural rigidity and minimal weight, crucial for competitive motorsports where every tenth of a pound impacts handling and acceleration. The compact 1.4 x 1.1 x 3.75-inch profile fits tight engine bay packaging without compromising flow rates or creating stress concentration points that lead to premature fatigue cracking in aluminum manifolds.

Custom fabricators, engine builders, and weekend warriors upgrading cooling systems on modified LS, small-block Chevy, Ford, or import platforms will find this fitting indispensable for creating leak-free, vibration-resistant connections that withstand sustained track sessions and street driving abuse. Installation requires standard wrench geometry—no specialized tools—making it ideal for bolt-on hose relocation projects or complete custom plumbing overhauls. Verify thread compatibility with your existing manifold or adapter fittings before ordering, as left-hand threading is not interchangeable with standard right-hand threads common on factory cooling system components.
