WESCO-3 - CGA-320 Brass Nipple, 1/4" NPT, 2" Length with Washer

Heavy-Duty CO2 Nipple for Welding Applications

In the world of welding and metal fabrication, the integrity of your gas delivery system is just as important as the quality of your power source. The Western Enterprises CGA-320 Nipple is designed to meet the demands of professional welders who rely on Carbon Dioxide (CO2) for shielding gas in MIG and flux-cored welding processes. This robust brass fitting ensures a consistent and leak-free flow of gas from the cylinder to your regulator, contributing to stable arc performance and high-quality welds.

Constructed from solid brass, this nipple is built to withstand the rigors of the shop floor. It resists mechanical damage and corrosion, maintaining its threads and sealing surfaces over years of use. The fitting features a CGA-320 inlet, specifically designated for Carbon Dioxide service, ensuring you never accidentally connect the wrong gas to your equipment. The outlet side sports a 1/4" NPT male thread, a standard size that fits the majority of industrial regulators and manifold blocks used in the welding industry.

Installation is straightforward thanks to the 11/16" hex section, which provides a solid grip for standard wrenches. The 2-inch length is optimized to fit comfortably into regulator inlets without adding unnecessary bulk to your setup. Crucially, this nipple includes a snap-in washer. In CO2 systems, the washer is the primary sealing element; without it, leaks are inevitable. The snap-in design keeps the washer in place during cylinder changes, reducing the risk of losing this vital component and ensuring a positive seal every time a fresh tank is connected.

With a pressure rating of 3000 PSIG, this nipple is fully capable of handling the pressure of a full CO2 cylinder. It is an essential spare part for any maintenance department or welding rig. Whether you are repairing a damaged regulator stem or building a custom gas manifold for a robotic welding cell, the Western Enterprises CGA-320 Nipple offers the professional-grade quality and safety assurance required for industrial operations.
