1/2-20 LH Tube End - 1in x .095in

The MEZIERE 1/2-20 LH Tube End is a precision weld-on threaded fitting designed for custom cooling system applications requiring left-hand female thread connection. This 1-inch tube end accommodates 0.095-inch wall tubing and delivers the exact thread engagement needed for reliable, leak-free hose and component attachment in high-performance engine builds.

Manufactured from chromoly steel in natural finish, this tube end offers superior strength and durability compared to standard steel fittings. The 1/2-20 left-hand thread specification ensures compatibility with OEM and aftermarket coolant lines designed to that standard. The weld-on design allows permanent, secure installation during custom radiator hose or water jacket fabrication, eliminating the need for mechanical unions or adapters that can loosen under vibration or thermal cycling.

Builders and fabricators working on custom cooling system configurations—including race engine builds, hot rods, and specialized automotive applications—rely on tube ends like this to create clean, direct connections without compromise. The left-hand thread orientation allows proper flow direction and prevents accidental loosening in systems where vibration is a concern. This is a single unit; order quantities reflect individual tube ends.

MEZIERE specializes in high-flow cooling solutions for performance engines, and their tube ends meet the precision tolerances expected in competition and custom build environments where cooling reliability is non-negotiable.
