How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Barbed Hose Fittings for Compressed Gas
Commonly used in low-pressure welding applications, these fittings connect downstream of your tank and pressure regulator. Slide the barbed end into rubber hose and secure with a crimp-on hose ferrule. Fittings are brass for good corrosion resistance.
Connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.

- Maximum Pressure: 200 psi @ 72° F
- Maximum Temperature: 120° F
- Attachment Type: Use Crimp-On Hose Ferrules
Compressed Gas Fill Valves
Mount these valves onto compressed gas tanks. Also known as Schrader valves—which are typically used with compressed air—they have an internal spring that holds the valve shut when you depress the pin to add, remove, or check the pressure of compressed gas. Made of brass, these valves thread onto nuts more easily than valves made of harder metal. They also have good corrosion resistance. Valves have a thread cap to protect the stem from accidental gas release.
Valves for use with butane are commonly used on torches. They’re nickel plated for extra corrosion resistance.
Valves for use with nitrogen are often used in central heating systems.
