F-31 - Western Enterprises F-31 CGA-295 to 1/4" NPT Male Brass Adapter

Precision Engineered Gas Connection Solution

The Western Enterprises F-31 Valve Stem Adapter is a specialized component designed to facilitate secure and reliable connections in industrial gas management systems. Manufactured from high-quality brass, this fitting is engineered to withstand the rigors of daily use while maintaining structural integrity under pressure. The primary function of the F-31 is to adapt a CGA-295 interface—commonly associated with inert gas mixtures and cryogenic liquid cylinders such as Argon, Nitrogen, and Helium—to a standard 1/4-inch National Pipe Taper (NPT) Male thread. This versatility makes it an essential component for facility managers and engineers designing custom gas manifolds, pigtails, or distribution panels.

Technical specifications are paramount when selecting gas fittings, and the F-31 delivers with a maximum working pressure rating of 500 PSIG (3,400 kPa). This pressure rating ensures that the adapter can safely handle the requirements of most medium-pressure gas distribution lines and regulator inlets. The brass construction not only provides the necessary mechanical strength but also offers excellent resistance to corrosion and oxidation, which is critical when the component is exposed to varying environmental conditions or stored for extended periods. The machining tolerances adhere strictly to Compressed Gas Association (CGA) standards, ensuring that the sealing surfaces mate perfectly with corresponding nuts and cylinder valves to prevent hazardous leaks.

In the context of system design, the F-31 serves as a bridge between specialized cylinder connections and general-purpose piping. The 1/4-inch NPT Male end allows for direct installation into regulators, flowmeters, ball valves, or block manifolds that utilize standard pipe threads. This eliminates the need for multiple intermediate bushings or couplings, thereby reducing the number of potential leak points in the system. Whether used in a laboratory setting for analytical instrumentation or in a heavy industrial environment for welding gas supply, the Western Enterprises F-31 provides a robust and compliant solution for inert gas connectivity.

Safety and compliance are at the forefront of the F-31's design. By utilizing the specific CGA-295 geometry, the fitting prevents accidental cross-connection with incompatible gas lines, such as those for oxygen or flammable gases. This "keyed" approach to gas fittings is a fundamental safety protocol in the industry. Users can be confident that this adapter is specifically intended for inert service, protecting both personnel and equipment from the dangers of gas mixing. With its combination of durable material, precise engineering, and adherence to safety standards, the Western Enterprises F-31 is the professional's choice for inert gas adaptation.
