WES7 - B-Size Oxygen Hose Nut, 9/16-18 RH Brass Fitting

Precision Brass Oxygen Hose Nut for Industrial Applications

The Western Enterprises WES7 is a high-quality hose nut designed specifically for oxygen gas service in industrial welding and cutting environments. Manufactured from premium brass, this component ensures a robust and spark-resistant connection point for oxy-fuel hose assemblies. The nut features a standard B-Size configuration, utilizing 9/16"-18 UNF threads, which is the industry norm for medium to heavy-duty gas equipment. Adhering to the Compressed Gas Association (CGA) standard 022, this fitting guarantees compatibility with a wide range of regulators, torches, and hose couplers designed for oxygen service.

Safety is paramount in gas distribution systems, and the WES7 incorporates specific design features to prevent cross-connection. The threads are Right-Hand (RH) oriented, a universal standard for oxygen fittings, distinguishing them from fuel gas fittings which utilize Left-Hand threads. This mechanical differentiation is critical for preventing dangerous mix-ups during equipment setup. The nut is rated for a maximum working pressure of 200 PSIG, making it suitable for standard oxygen supply pressures used in welding, brazing, and heating applications.

Physically, the nut is machined with an 11/16" hex profile, allowing for secure tightening using standard shop wrenches. The 0.625-inch length provides ample thread engagement to secure the hose nipple (sold separately) firmly against the mating surface, ensuring a gas-tight seal. As a component exposed to high-pressure oxygen, the choice of brass is deliberate; it offers excellent resistance to oxidation and does not spark if struck, reducing ignition risks. This product is manufactured in the United States, ensuring high quality control standards.

This hose nut is an essential component for MRO (Maintenance, Repair, and Operations) professionals tasked with assembling or repairing gas hoses. Whether fabricating custom hose lengths or replacing damaged fittings on existing lines, the WES7 provides the reliability and compliance required for professional gas apparatus. It is important to note that this item is the nut only; a corresponding ferrule and nipple are required to complete the hose termination.
