1/2-20 LH Tube End - 1in x .058in

The 1/2-20 LH Tube End - 1in x .058in is a precision weld-on fitting designed for high-performance cooling and fuel system applications where left-hand thread engagement is critical. This chromoly tube end serves as a direct connection point in radiator hoses, transmission coolers, and custom cooling circuits where standard right-hand fittings would create installation conflicts or safety concerns. Built by MEZIERE, a trusted name in performance thermal management, this tube end is engineered to handle the demands of racing, hot rodding, and custom fabrication work where reliability cannot be compromised.

Constructed from chromoly steel in its natural finish, this tube end features a 1/2-20 left-hand female thread that accepts standard -8 AN fittings and adapters commonly used in performance cooling and fuel delivery systems. The 1-inch tube diameter accommodates standard automotive hose with a 0.058-inch wall thickness, ensuring proper fit and leak-free connections under pressure and thermal cycling. The weld-on design allows for permanent, full-strength integration into custom fabricated cooling circuits, radiator tanks, and coolant manifolds where vibration resistance and long-term durability are non-negotiable. Left-hand threading prevents accidental loosening in applications where rotational forces or vibration could compromise right-hand connections.

This fitting is ideal for fabricators, engine builders, and performance shops constructing custom cooling systems, supercharger coolers, or transmission oil coolers that demand precision fitment and thread-specific orientation. Mechanics and enthusiasts working on vintage hot rods, modern drag cars, or custom water-cooled engine builds will find this tube end essential for applications where standard tube ends cannot accommodate their specific plumbing layout. Installation requires TIG or MIG welding to the existing tube or manifold; proper preparation and welding technique ensure maximum strength and leak prevention in demanding thermal and pressure environments.
