1/2-20 LH Tube End - 7/8in x .058in

The 1/2-20 LH Tube End – 7/8in x .058in from MEZIERE is a precision-engineered weld-on coupling designed for custom cooling system fabrication and performance plumbing applications. This left-hand threaded tube end serves as a critical connection point in radiator hose routing, water line distribution, and thermal management system builds. Fabricators, performance shops, and restoration specialists rely on this component to create reliable, leak-free connections in high-temperature fluid transfer environments where standard fittings may not accommodate custom tube configurations.

Manufactured from chromoly steel in its natural finish, this tube end features a 1/2-20 left-hand female thread that mates with corresponding 1/2-20 LH male fittings, ensuring positive engagement and secure assembly. The design accommodates a 7/8-inch outer diameter tube with 0.058-inch wall thickness—a common specification in automotive and industrial cooling circuits. The weld-on construction allows for permanent integration into custom-fabricated tube assemblies, providing superior vibration resistance and reliability compared to slip-fit connections. Chromoly's superior strength-to-weight ratio and thermal stability make it ideal for performance applications where standard steel would be insufficient.

This fitting is essential for builders constructing custom radiator hoses, intercooler pipes, and coolant distribution systems in motorsports, classic car restorations, and high-performance engine builds. The left-hand thread designation prevents accidental loosening in applications where rotational forces might otherwise compromise a standard right-hand connection. Proper installation requires welding to a matching 7/8-inch OD tube, making this component ideal for shops equipped with TIG or MIG welding capabilities. Verify thread engagement and alignment before welding to ensure optimal sealing and longevity in your cooling system assembly.
