5/8-18 LH Tube End - 1-3/8in x .095in

The 5/8-18 LH Tube End - 1-3/8in x .095in from MEZIERE is a precision-engineered threaded coupling component designed for high-performance cooling and fluid transfer systems in motorsports and tactical vehicle applications. This left-hand (LH) tube end serves as a critical interface in custom radiator, transmission cooler, and engine oil cooling line assemblies where secure, leak-proof connections are essential.

Manufactured to MEZIERE's strict quality standards, this component features a 5/8-18 left-hand thread specification with a 1-3/8-inch outer diameter and .095-inch wall thickness, delivering the structural integrity required for high-pressure fluid systems operating in demanding environments. The left-hand threading prevents accidental loosening due to rotational forces and vibration common in vehicle and equipment operation, ensuring reliability under extreme thermal and pressure conditions.

This tube end is ideal for custom cooling system builds, high-performance engine builds, and specialized vehicle platforms where OEM components are unavailable. The precision bore and thread geometry ensure repeatable, reliable sealing when paired with matching hose barbs, fittings, and adapters, eliminating the risk of catastrophic coolant loss or system failure during critical operations.
