Western Enterprises CGA-350 Nut - Hydrogen & Natural Gas - Brass .830-14 NGO LH

Reliable Replacement CGA-350 Nut for Regulators and Manifolds

When you are out in the field or working in the shop, a stripped or damaged regulator nut can bring your entire operation to a halt. The Western Enterprises WES82 is the industry-standard replacement nut for CGA-350 connections, commonly found on Hydrogen and Natural Gas equipment. If you are rebuilding a regulator, repairing a pigtail, or constructing a custom gas manifold, this heavy-duty brass nut delivers the fit and performance you need to get back to work safely.

Safety is built into the design of the WES82. It features the standard Left-Hand (LH) threads required for fuel gas connections, easily identifiable by the notch on the nut (a standard industry marker for LH threads). This ensures you never accidentally hook up a fuel gas line to an oxidizer system, preventing dangerous cross-connections. The 1-1/8" hex design provides ample surface area for your wrench, allowing you to tighten the connection securely without rounding off the edges, even after years of service.

This nut is rated for 3000 PSIG, making it suitable for full cylinders and high-pressure manifold banks. It is machined from solid brass, which is the material of choice for gas fittings due to its spark resistance and durability. Unlike cheaper alternatives that might deform under pressure or cross-thread easily, Western Enterprises fittings are known for their clean, precise threads that spin on smoothly and hold tight. This specific nut (WES82) pairs with a standard CGA-350 nipple (not included) to form the complete inlet connection.

Don't compromise on your gas equipment. Using the correct CGA fittings is essential for preventing leaks and ensuring the safety of your welding or cutting setup. Whether you are running a hydrogen flame setup or a natural gas heating torch, the WES82 provides the secure link between your gas supply and your equipment. Keep a few spares in your maintenance kit to ensure you are never stuck with a bad connection when a delivery of fresh cylinders arrives.
