3/8-24 LH Tube End - 1in x .058in

The 3/8-24 LH Tube End - 1in x .058in from MEZIERE is a precision weld-on tube fitting engineered for high-performance cooling system fabrication and custom fluid line assembly. This left-hand female thread adapter serves engineers, fabricators, and performance enthusiasts who demand reliable, leak-free connections in demanding thermal management applications. The tube end's threaded design allows secure connection of hoses and fittings while the weld-on base provides permanent, vibration-resistant mounting to chromoly tubing substrates.

Constructed from chromoly steel and finished in natural (uncoated) condition, the 3/8-24 LH Tube End features a 3/8-24 inch left-hand female thread specification, making it compatible with standard metric-threaded hose barbs, adapters, and AN-style fittings. The tube end accommodates 1-inch outer diameter tubing with a 0.058-inch wall thickness—a common specification in race-car radiator pans, custom water jacket fabrication, and transmission cooler plumbing. Chromoly's superior strength-to-weight ratio and weld integrity ensure the fitting withstands thermal cycling, vibration, and system pressure without material degradation or thread stripping.

This fitting is ideal for custom cooling system builders, drag racing teams, and hot rod fabricators seeking OEM-quality tube ends for bespoke applications where standard tube clamps are insufficient. The left-hand thread configuration prevents accidental loosening under high-vibration conditions common in motorsports. Installation involves TIG or MIG welding the fitting base to chromoly tubing; proper surface preparation and heat-treating post-weld ensure maximum strength and corrosion resistance. Each unit ships individually, allowing builders to purchase only the quantity required for their specific project.
