OVERVIEW

Secure Your Gas Connections with the Western Enterprises WES10

When it comes to gas welding and cutting equipment, the integrity of your connections is paramount for both safety and performance. The Western Enterprises WES10 Hose Nut is a premium replacement part designed to keep your acetylene and fuel gas lines secure and leak-free. Whether you are repairing an existing hose assembly or building a new custom setup, this A-Size nut provides the reliability you expect from a top-tier manufacturer like Western Enterprises. Made right here in the USA, this nut is crafted from solid brass, ensuring it stands up to the rigors of daily shop use while resisting corrosion and wear.

Safety is built into the design of the WES10. It features a Left-Hand (LH) thread pattern, specifically 3/8"-24 UNF, which is the industry standard for A-Size fuel gas connections. This left-hand thread is a critical safety measure that prevents you from accidentally connecting a fuel gas hose to an oxygen regulator or torch, eliminating the risk of dangerous cross-connections. You can quickly identify this nut by the groove notched into the hex, a universal sign for left-hand threads in the welding trade. This simple yet effective feature gives you peace of mind every time you set up your gear.

The WES10 is ideal for light-duty applications such as jewelry making, light fabrication, and HVAC work where A-Size fittings are common. Its 7/16" hex shape ensures you can easily tighten it with standard tools to achieve a perfect seal. Rated for up to 200 PSI, this nut handles the pressure requirements of standard acetylene setups with ease. Don't compromise on the small parts that keep your operation running safely; choose the Western Enterprises WES10 for a precise fit and durable performance. It is compatible with any standard CGA-021 male fitting, making it a versatile addition to your maintenance kit.
