3/4-16 RH Tube End - 1-1/4in x .120in

The 3/4-16 RH Tube End - 1-1/4in x .120in is a precision weld-on connector designed for custom cooling and fuel system fabrication where threaded female connections are required. This tube end serves as a permanent structural and flow interface, ideal for builders working with chromoly tubing in high-performance automotive applications, racing systems, and industrial hydraulic assemblies. The right-hand thread orientation ensures compatibility with standard male fittings and guarantees leak-free assembly when properly welded and torqued.

Manufactured from chromoly steel in its natural finish, this tube end combines strength with weldability—critical for applications subject to vibration and thermal cycling. The 3/4-16 right-hand female thread accepts matching male connectors, while the 1-1/4-inch tube outer diameter with 0.120-inch wall thickness specification ensures structural integrity and compatibility with standard tubing schedules used in performance builds. Chromoly's superior tensile strength compared to mild steel provides enhanced durability in demanding environments, making this fitting ideal for systems requiring both reliability and custom fabrication flexibility.

This component benefits custom fabricators, engine builders, and race technicians who need tailored tube routing without compromising joint integrity. It installs via TIG or MIG welding to the end of prepared 1-1/4-inch tubing, creating a permanent assembly ready for threaded fitting attachment. Weighing just 0.28 pounds, it remains lightweight while delivering the structural characteristics required in competition and street-rod applications where every pound and connection point matters.
