Optimus valve cartridge 450g with screw thread, Lindal system.

Optimus gas cartridges have a gas mixture that is ideal for cold weather conditions and high heights. The valve indicator also shows whether the cartridge is used or new. Thanks to the self-closing safety valve, you can unscrew the gas stove and gas lamp from the cartridge even if it is not yet completely empty. This gives you the advantage of being able to transport and store the cartridge separately or to operate different appliances in succession on one cartridge. The worldwide standardization of the Lindal screw-in system is available from many manufacturers of valve cartridges.
