WES92 - CGA-580 Brass Inlet Nut for Argon, Helium, Nitrogen Regulators

Precision Engineered CGA-580 Connection Hardware

The Western Enterprises WES92 Inlet Nut is a critical component designed for the safe and efficient transfer of inert gases in industrial, laboratory, and welding environments. Manufactured to strict Compressed Gas Association (CGA) standards, this nut is specifically engineered for the CGA-580 connection type, which is the industry standard for Argon, Helium, and Nitrogen gas services. The component features a precise .960"-14 NGO Right-Hand Male thread, ensuring a secure and compatible fit with corresponding cylinder valves and regulator nipples.

Constructed from high-grade brass, the WES92 offers superior durability and resistance to corrosion, making it suitable for long-term use in demanding shop environments. Brass is the material of choice for these applications due to its non-sparking properties and ability to maintain thread integrity under high torque. This inlet nut is rated for a maximum working pressure of 3000 PSIG, providing a robust safety margin for standard high-pressure gas cylinders. The 1-1/8" RC Hex design allows for easy installation and removal using standard wrenches, ensuring that technicians can achieve the necessary torque for a leak-tight seal without damaging the hardware.

In professional gas distribution systems, the integrity of every connection point is paramount. The WES92 is machined with tight tolerances to prevent gas leakage, which is essential not only for safety but also for process consistency. Whether used in a manifold system, a direct regulator-to-cylinder connection, or as a replacement part for worn equipment, this Western Enterprises component delivers the reliability expected by industrial MRO professionals. It is a direct replacement for damaged nuts on flowmeters and regulators, allowing for cost-effective repair rather than full unit replacement.

This product is manufactured in the United States, adhering to rigorous quality control processes. It is designed to accommodate a full range of gas service requirements within the inert gas spectrum. Users should verify that their specific application requires a CGA-580 connection before installation. Note that this item is the nut only; the corresponding nipple must be selected separately based on the specific regulator or tailpiece requirements.
