WIKBG-177 - Western Enterprises 177 CGA-540 Oxygen Nut, Brass

Precision Brass Connection for Oxygen Service

The Western Enterprises 177 is a high-quality cylinder connection nut designed specifically for Oxygen service. Manufactured to strict Compressed Gas Association (CGA) standards, this component features the CGA-540 connection profile, ensuring safe and compatible coupling with industrial oxygen cylinders and manifold systems. Constructed from solid free-cutting brass, the nut offers excellent durability and resistance to deformation under torque, which is critical for maintaining a leak-tight seal at high cylinder pressures.

This nut is engineered with a .903"-14 NGO-RH-INT thread specification, denoting a right-hand thread that is standard for oxygen and inert gas fittings to prevent accidental cross-connection with fuel gas lines (which typically use left-hand threads). The internal geometry is machined to precisely seat a corresponding CGA-540 nipple (such as Western Enterprises Part #17), creating a metal-to-metal seal or accommodating a washer depending on the specific nipple design used. It is an essential component for fabricating pigtails, repairing regulators, or assembling custom gas distribution manifolds.

In industrial MRO environments, the integrity of gas connections is paramount for safety and efficiency. The Western 177 nut undergoes rigorous quality control to ensure thread accuracy and structural integrity. It is rated for standard compressed gas cylinder pressures, typically up to 3000 PSI, making it suitable for a wide range of welding, cutting, and medical applications. Whether replacing a worn nut on a flowmeter or building a new high-pressure whip, this Western Enterprises component delivers the reliability professionals demand.
