## Long description

Refill gas cartridge for Castolin portable torches and soldering tools. The 300 g canister contains a calibrated butane–propane blend and is fitted with a 7/16" valve designed for compatible torch connectors. It provides a compact, replaceable fuel source for heating, soldering and brazing tasks where portability and quick cartridge exchange are required.
Advantages
The cartridge offers a stable flame output and consistent fuel flow due to the formulated butane–propane mixture. Its 300 g capacity balances runtime and portability for on-site work. The standard 7/16" valve interface simplifies replacement and ensures compatibility with torches that accept this valve type. As a disposable canister, it eliminates the need for bulk liquid fuel handling and reduces setup time for small installations and repairs.
Suitable for
Portable torches and handheld soldering tools designed for gas cartridges with a 7/16" valve

How to use
Ensure the torch and cartridge connectors are clean and undamaged before installation. Follow the torch manufacturer's instructions for replacing cartridges: turn off the torch, allow it to cool, align the 7/16" valve and securely attach the cartridge until properly seated. Open the torch valve slowly and check for a steady flame; adjust flame settings as required for the task. After use, close the torch valve and detach the cartridge if required by the torch design. Store unused cartridges upright in a cool, well-ventilated area away from heat sources and open flames.
Usage recommendations
Use only in torches and soldering tools that specify compatibility with 7/16" valve cartridges and a butane–propane fuel mix. Do not puncture or incinerate empty canisters. Observe local regulations and safety guidance for storage, transport and disposal of pressurized fuel cartridges.
