WES62 - CGA-540 Oxygen Regulator Inlet Nut, Brass, 3000 PSIG

Precision-Engineered CGA-540 Inlet Nut for Oxygen Service

The Western Enterprises WES-62 Inlet Nut is a critical component designed to facilitate the safe and secure connection of gas regulators to compressed gas cylinders. Specifically engineered for oxygen service, this inlet nut adheres strictly to the Compressed Gas Association (CGA) standard V-1 for CGA-540 connections. In the realm of industrial gas handling, precision and compliance are paramount; the WES-62 delivers on both fronts with a robust brass construction that ensures durability and resistance to deformation under high torque.

The nut features a .908"-14 NGO right-hand female thread, a specification universally adopted for industrial oxygen cylinders in the United States and many other regions. This specific thread profile is designed to prevent cross-connection with incompatible gases, a vital safety feature in environments where multiple gas types are present. The use of brass is deliberate; as a non-ferrous metal, brass is non-sparking, making it the material of choice for oxygen systems where the risk of ignition must be minimized. Furthermore, brass offers excellent machinability, allowing for tight tolerances that ensure a smooth engagement with the cylinder valve threads, reducing wear over repeated cycles of connection and disconnection.

Rated for a maximum working pressure of 3000 PSIG, the WES-62 is capable of handling the standard pressures found in full industrial oxygen cylinders. This high-pressure rating is a testament to the quality of the material and the thickness of the nut's walls. The external geometry of the nut is a 1-1/8" hex, providing ample surface area for a standard wrench to apply the necessary torque for a leak-tight seal without rounding off the edges. This is particularly important in industrial settings where equipment is frequently moved and reassembled.

When assembling a regulator or a pigtail hose, the inlet nut works in conjunction with a matching nipple (sold separately) to form the sealing surface against the cylinder valve. It is crucial that the mating surfaces are clean and free of any oil or grease, as these contaminants can react violently with high-pressure oxygen. The WES-62 is supplied clean and ready for oxygen service, ensuring that it meets the stringent cleanliness levels required for safe operation. Whether used in heavy manufacturing, laboratory analysis, or medical gas distribution (where CGA-540 is applicable), this inlet nut provides the reliability and safety assurance demanded by professionals.
