5/8-18 RH Tube End - 1in x .065in

The 5/8-18 RH Tube End is a weld-on threaded fitting designed for hydraulic, pneumatic, and mechanical tube assemblies requiring a secure, permanent connection. This right-hand female thread component accepts 5/8-18 male fittings and is engineered for applications demanding high-pressure reliability and structural integrity. Commonly used in industrial equipment, agricultural machinery, off-road vehicles, and custom fabrication projects, this tube end provides a repeatable, code-compliant connection method that eliminates potential leakage points associated with loose couplings.

Manufactured from chromoly steel in natural finish, the 5/8-18 RH Tube End accommodates 1-inch outer diameter tubing with 0.065-inch wall thickness, making it compatible with standard Schedule 40 and similar wall-thickness specifications. The chromoly material provides superior tensile strength and fatigue resistance compared to mild steel, essential for applications experiencing vibration or cyclic pressure loads. The weld-on design requires permanent fusion to the tube end, creating a monolithic assembly that distributes stress evenly and resists catastrophic failure under extreme conditions.

This fitting is ideal for fabricators, machine shops, and motorsports builders who prioritize pressure integrity and structural durability over quick-disconnect convenience. Installation requires a qualified welder capable of chromoly steel procedures to ensure full penetration and material compatibility. The right-hand thread orientation ensures intuitive assembly direction and prevents cross-threading during field mating. Weighing only 0.16 lbs and measuring 1.4 by 1.15 by 3.95 inches, the 5/8-18 RH Tube End fits compact manifolds and tight engine bay configurations while maintaining robust load-carrying capacity for demanding hydraulic systems and custom tube routing applications.
