CGA-680 Brass Inlet Nipple with Filter, 1/4" NPT, 3" Length

Protect Your Regulator and Ensure Clean Gas Flow

For professional welders and fabricators, equipment reliability is key to maintaining productivity. The Western Enterprises WES680-3SF Inlet Nipple is more than just a connector; it is a safeguard for your gas regulation equipment. Designed to fit CGA-680 cylinder valves—commonly found on high-pressure cylinders for inert gases like Argon and Nitrogen—this nipple ensures a secure link between your gas supply and your regulator or manifold system. If you are working with high-pressure setups, typically found in heavy fabrication or specialized TIG welding applications, this brass nipple provides the durability you need.

The standout feature of this nipple is its built-in filter. Gas cylinders can sometimes contain small particles of rust, dust, or debris accumulated during transport or refilling. Without protection, these particles can be blasted into your regulator at high speed when the cylinder valve is opened, scoring the internal seat and causing pressure creep or leaks. The WES680-3SF's sintered filter acts as a first line of defense, catching these impurities and ensuring that only clean gas reaches your regulator. This simple addition can save you the cost and hassle of premature regulator repairs or replacements.

Constructed from solid brass, this nipple is built to withstand the rough conditions of a welding shop. It features a 3-inch length, giving you plenty of room to get a wrench on the 7/8" hex nut for a tight, secure installation. The 1/4" NPT thread makes it easy to install into most standard regulator bodies or manifold pigtails. Whether you are setting up a central gas system or upgrading your portable rig, using a filtered nipple like the WES680-3SF is a smart investment in the longevity of your welding gear. It supports pressures up to 7500 PSIG, giving you peace of mind when cracking open those high-pressure tanks.
