5/16-24 LH Tube End - 5/8in x .058in

The MEZIERE 5/16-24 LH Tube End (Part No. RE1011AL) is a weld-on, threaded tube fitting designed for precision coolant line fabrication in high-performance engine applications. This left-hand female thread tube end accepts 5/8-inch diameter tubing with a 0.058-inch wall thickness and is constructed from chromoly steel, offering superior strength and thermal stability compared to standard steel alternatives.

The 5/16-24 thread specification ensures compatibility with standard metric coolant system components commonly found in racing and custom engine builds. The left-hand threading prevents accidental loosening during high-vibration operation—a critical feature in competition and high-RPM environments. Chromoly construction provides enhanced fatigue resistance and maintains structural integrity under the thermal cycling and pressure cycling that occurs in modern cooling systems. The weld-on design allows for permanent, leak-free integration into custom tubing manifolds without relying on threaded connections that can fail under extreme conditions.

This fitting is essential for fabricators and engine builders who demand precision coolant routing and maximum reliability. It suits custom water jacket modifications, aftermarket cooling system builds, and high-horsepower engine applications where standard fittings may not provide adequate safety margins. The natural finish allows for painting or coating to match system aesthetics or provide additional corrosion protection in harsh environments.

MEZIERE is recognized for manufacturing precision cooling components and tube fittings engineered for race-proven performance. This 5/16-24 LH tube end carries the specifications and material standards required for professional-grade engine cooling system fabrication.
