Threaded Hose-to-Propane-Torch Adapters for Compressed Gas

- Maximum Pressure: 200 psi @ 72° F
- Maximum Temperature: 120° F
These adapters allow you to connect a hose to a propane torch. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance. Fittings have left-hand threads that are identified with a notch in the nut.
Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.
