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

The 5/8-18 LH Tube End - 1in x .095in is a precision weld-on fitting designed for use in custom cooling systems, fuel lines, and hydraulic applications, particularly in high-performance vehicle builds. This component is essential for mechanics and fabricators looking to create reliable, leak-free connections in demanding environments.

Constructed with a 5/8-18 left-hand thread, this tube end features a 1-inch outer diameter and a wall thickness of 0.095 inches, making it compatible with standard 1-inch seamless or DOM steel tubing. The left-hand thread design ensures proper flow control and prevents loosening due to vibration in rotating or pressurized systems. Its compact design allows it to fit into tight spaces while maintaining performance.

Ideal for fabricators working on LS-based engines, turbocharged builds, or vintage restorations, this fitting simplifies the fabrication process by eliminating the need for flanged adapters. It is particularly useful in custom radiator tanks, catch cans, and coolant manifolds, where reliability and performance are paramount.
