WESAW-427 - Inert Gas Adapter B-Size Male to 1/4 NPT Male Brass

Western Enterprises AW-427 Inert Gas Adapter Overview

The Western Enterprises AW-427 is a premium-grade brass adapter designed specifically for inert gas applications. In the complex world of industrial gas distribution and welding setups, the integrity of every connection is paramount. This adapter serves as a critical bridge between different thread standards, allowing for the seamless integration of hoses, regulators, and machine ports. Manufactured from high-quality brass, the AW-427 offers excellent resistance to corrosion and mechanical wear, ensuring a long service life even in demanding workshop environments.

Technical Specifications and Compatibility

This adapter features a dual-thread configuration to solve common connectivity challenges. On one end, it sports a B-Size 5/8"-18 UNF Right Hand Male thread, which is the industry standard for inert gas hose connections. On the opposing end, it utilizes a 1/4" NPT (National Pipe Taper) Male thread, widely used in regulators, flowmeters, and hard-piping systems. The precision machining of these threads ensures a tight, leak-proof seal when properly installed. The unit is rated for a maximum working pressure of 200 PSIG, providing an ample safety margin for most standard inert gas shielding operations used in TIG and MIG welding.

Material Quality and Safety

Safety is a non-negotiable aspect of gas equipment, and the AW-427 is built to meet these rigorous demands. The solid brass body is not only durable but also compatible with a wide range of inert gases, including Argon, Helium, and Nitrogen. The 11/16" RC Hex design allows for secure gripping with standard wrenches, preventing slippage during installation. By using genuine Western Enterprises fittings, operators can ensure their systems maintain pressure integrity and minimize the risk of gas leaks that could compromise weld quality or safety. Whether you are setting up a new laboratory gas manifold or replacing a worn component on a welding cart, this adapter delivers the reliability professionals expect.
