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

The MEZIERE 5/8-18 RH Tube End is a precision weld-on threaded fitting designed for custom cooling system fabrication and high-performance engine builds. This right-hand thread component is essential for mechanics and fabricators who demand OEM-quality connections when constructing or modifying radiator hoses, heater circuits, and fluid lines on competition engines and street performance vehicles.

Manufactured to MEZIERE's exacting standards, the 5/8-18 RH Tube End features a tubing diameter of 1 inch OD with a wall thickness of 0.095 inches, making it suitable for a variety of cooling system applications. The right-hand thread configuration (5/8-18) ensures straightforward installation without reverse-threaded confusion, and the weld-on design provides a permanent, leak-free connection when properly TIG-welded to custom steel tubing.

This fitting is particularly beneficial for fabricating custom radiator hoses, upgrading cooling circuits on supercharged or turbocharged builds, or restoring classic vehicles with unique cooling configurations. Its compact weight of just 0.15 pounds allows for easy integration into tight engine bays while maintaining structural integrity under system pressure and thermal cycling.
