3/8-24 LH Tube End - 3/4in x .065in

The 3/8-24 LH Tube End is a precision weld-on threaded fitting engineered for hydraulic and pneumatic systems requiring left-hand female connections. Designed for professionals assembling custom tube assemblies, fuel systems, brake lines, and high-pressure fluid transfer applications, this component provides a secure, leak-free connection point on 3/4-inch diameter tubing. The left-hand thread design prevents accidental loosening in rotational environments and is standard in critical safety systems where positive thread engagement is non-negotiable.

Manufactured from chromoly steel in natural finish, the 3/8-24 LH Tube End accommodates 0.065-inch wall thickness tubing and features a male welding configuration for permanent fusion to your tube assembly. The 3/8-24 left-hand thread specification ensures compatibility with standard metric and industrial hydraulic ports, while the chromoly construction delivers superior tensile strength and resistance to vibration-induced fatigue. At just 0.07 pounds, this compact fitting minimizes system weight without sacrificing durability or pressure-holding capacity, making it ideal for weight-conscious applications in aerospace, automotive, and industrial equipment manufacturing.

Technicians and fabricators working with custom hydraulic assemblies, racing fuel systems, and precision pneumatic tubing benefit most from this tube end fitting. Installation requires TIG or MIG welding to the tube body—proper heat control ensures full strength development without material degradation. The natural chromoly finish can be painted or plated for corrosion protection in harsh environments. This fitting is sold individually and is essential for anyone building or repairing high-reliability fluid transfer systems where thread integrity and weld quality directly impact safety and performance.
