B-Size Oxygen Hose Splicer, Male-to-Male Brass Coupler

Extend Your Reach with Quality Brass Fittings

Don't let short hoses limit your movement around the workshop or job site. The Western Enterprises WES30 Oxygen Hose Coupler is the perfect tool for extending your welding and cutting range. Designed to connect two standard oxygen hoses together, this coupler allows you to create longer lines instantly, giving you the flexibility to work on large projects without moving your heavy cylinder cart. Made from solid brass, this B-Size coupler is built to withstand the rigors of daily use, resisting wear and tear while maintaining a secure, leak-proof connection.

Simple and Safe Installation

The WES30 features standard 9/16"-18 UNF male threads on both ends, fitting perfectly with the female B-size nuts found on most commercial oxygen hoses. The right-hand thread design is a universal safety standard for oxygen equipment, ensuring you never accidentally mix it with fuel gas lines. Installation is quick and easy; the 5/8" hex center allows you to tighten the connection securely with a wrench, ensuring gas-tight integrity up to 200 PSI. Whether you are splicing hoses for a repair or simply need extra length to reach a weldment, this coupler is a toolbox essential.

It comes cleaned for oxygen service right out of the package, so you can install it with confidence knowing it is free of dangerous hydrocarbons or oils. Ideal for welders, fabricators, and maintenance crews, this simple yet effective adapter ensures your gas delivery system remains efficient and safe. Keep a few in your kit to ensure you are never caught short on hose length again.
