FAQ
The inlet connection is a CGA-295, which is the standard for inert gases and cryogenic liquids.
The outlet features a 1/4-inch NPT (National Pipe Taper) Male thread.
The Western Enterprises F-31 is rated for a maximum working pressure of 500 PSIG (3,400 kPa).
No, CGA-295 is specifically for inert gases. Oxygen requires a different CGA connection (typically CGA-540) to prevent safety hazards.
It is machined from solid brass, offering durability and corrosion resistance.
Typically, the F-31 refers to the stem/adapter body itself. Depending on the specific kit, a nut may need to be purchased separately if not reusing an existing one.
CGA-295 is often found on liquid cylinders (dewars) for the gas use or vent ports, but always verify the pressure rating (500 PSIG) matches your application.
Common gases include Argon, Nitrogen, and Helium, often in cryogenic liquid cylinder formats or specific inert gas mixtures.
