Western Enterprises WES20 Brass Hose Nipple 3/8 Inch B-Size

Reliable Hose Repair for Welders and Fabricators

When you are in the middle of a fabrication job, a damaged hose can bring your entire operation to a halt. The Western Enterprises WES20 Hose Barb Nipple is the essential repair part you need in your toolbox to get back to work quickly and safely. Designed specifically for 3/8-inch welding hoses, this brass nipple allows you to repair a cut or burst line or attach new fittings to a bulk hose with confidence. Don't rely on makeshift fixes when dealing with compressed gases; use the fitting designed for the job.

This nipple features a standard B-Size connection, which is the most common fitting size for industrial oxy-fuel equipment. Because the sealing surface is universal for this size, you can use this same nipple with either green oxygen nuts (CGA 022) or red fuel gas nuts (CGA 023). This means you don't need to carry different nipples for your oxygen and acetylene lines—one part does it all. The barbed end is designed to slide tightly into 3/8" I.D. hose, providing a solid foundation for your crimp or clamp. Once secured, it handles up to 200 PSIG of pressure, ensuring your gas flow remains steady and leak-free.

Built from solid brass, the WES20 is tough enough to handle the rough conditions of a welding shop or job site. Brass is naturally resistant to rust and won't spark if dropped, adding an extra layer of safety to your equipment setup. The 1.478-inch length gives you plenty of room to slide a nut back and properly seat the ferrule or clamp without crowding the threads. Whether you are building a custom-length extension hose for a large project or fixing a leak near the regulator, this nipple provides the professional-grade connection your torch needs.

Installation is straightforward. Simply cut your hose square, slide on your B-size nut and ferrule (or clamp), insert the WES20 nipple fully into the hose, and crimp or tighten. The result is a factory-quality connection that restores the integrity of your gas delivery system. Keep a few of these in your organizer bin so you are never caught off guard by a worn-out hose fitting again.
