143 - Western Enterprises CGA-346 Brass Air Nipple, 1/4" NPT x 2-1/2"

High-Performance CGA-346 Brass Nipple for Industrial Air Service

The Western Enterprises CGA-346 Air Nipple is a critical component for professionals designing, maintaining, or repairing compressed air systems in industrial, welding, and laboratory environments. Engineered to meet the specific dimensional and safety standards of the Compressed Gas Association (CGA), this nipple ensures a secure and compliant connection for gas service designated as "Air." The unit is precision-machined from high-grade brass, a material selected for its excellent machinability, durability, and resistance to corrosion in non-corrosive gas applications.

This specific model features a 1/4-inch National Pipe Taper (NPT) male thread, the standard for most industrial piping and regulator body connections, ensuring broad compatibility with existing equipment. The nipple has an overall length of 2.510 inches (nominally 2-1/2 inches), providing ample reach for manifold spacing or regulator clearance. The body includes a machined 11/16-inch RC Hex section, allowing technicians to apply the necessary torque for a gas-tight seal without damaging the fitting. With a maximum pressure rating of 3000 PSIG, this nipple is robust enough to handle standard high-pressure compressed air cylinders and manifold systems safely.

Western Enterprises is known for its strict adherence to quality control and safety standards. This product is manufactured in the United States and is designed to withstand the rigors of daily industrial use. It is important to note that while brass is the industry standard for this application, users should be aware of Proposition 65 warnings regarding lead content, which is common in free-machining brass alloys. This nipple is strictly for Air service and should not be used with incompatible gases.

Whether you are assembling a custom gas distribution manifold, replacing a worn inlet on a regulator, or configuring a laboratory gas setup, the Western CGA-346 nipple provides the reliability and precision required for high-pressure pneumatic systems.
