3/4-16 RH Tube End - 1-1/4in x .095in

The 3/4-16 RH Tube End is a precision weld-on threaded fitting engineered for high-strength hydraulic, pneumatic, and fuel line assemblies. Designed for technicians, fabricators, and OEM suppliers who demand reliable tube connections, this fitting provides a permanent, secure joint when TIG or MIG welded to chromoly or steel tubing. Right-hand female threading ensures directional flow control and prevents cross-threading during installation, making it ideal for applications where safety and repeatability are non-negotiable.

Manufactured from chromoly steel and finished in natural condition, this tube end accommodates 1-1/4 inch outer diameter tubing with a 0.095 inch wall thickness—a common specification in aerospace, automotive, and industrial hydraulic systems. The 3/4-16 right-hand thread pattern ensures compatibility with standard NPT (National Pipe Thread) or equivalent connectors, while the weld-on design eliminates stress concentration points created by mechanical fastening. Chromoly's superior tensile strength and fatigue resistance make it the material choice for high-pressure applications where temperature cycling and vibration loads are factors.

This fitting is ideal for custom tube fabrication, motorsports frame assembly, agricultural equipment repair, and aftermarket performance builds where OEM tubing replacements are unavailable or cost-prohibitive. Installation requires proper welding technique—recommended for experienced TIG welders using appropriate chromoly rod and shielding gas—to maintain structural integrity and pressure rating. Users should verify thread compatibility with mating connectors and confirm tubing dimensions before ordering to ensure precise fit and leak-free operation under operating conditions.
