Troubleshooting & FAQ
How do I know if this cylinder fits my torch?
This cylinder uses a standard CGA 600 connection, which is common for most hand torches, including the Bernzomatic models listed in our compatibility table. Always check your device's manual to confirm it accepts a 14.1 oz propane cylinder with a CGA 600 fitting.
How should I store the propane cylinder?
Store cylinders upright in a well-ventilated area away from living spaces, heat sources, open flames, and sparks. Do not store them in a vehicle. Always ensure the protective cap is on when not in use.
What are the signs of a leaking or faulty cylinder?
A distinct rotten egg/garlic smell (from the added odorant), a hissing sound near the valve, or visible frost on the connection may indicate a leak. If you suspect a leak, move the cylinder outdoors immediately, away from ignition sources, and do not use it.
