Bushcraft Essentials BE Fire Piston - Including Ferroceirum rod & Char Cord The most fascinating way to make fire: A blow to the piston will ignite tinder, which has been inserted into the fire piston. The compression heats up the air to such a high degree that tinder will ignite. A diesel engine operates in the same manner. In case of emergencies you will always have at least one reliable source of fire available. The piston and the vent are perfectly sealed with double gaskets. The piston gaskets are made of high quality nitrile rubber and are therefore extremely resistant to abrasion, heat and cold and are compatible with all lubricants. The package includes: - Fire Piston - Ferrocerium rod - Char Cord - 4 replacement gaskets - Instructions Additional char cord can be ordered from us. Weight: 160g ; Material: precision CNC machined from a special aluminum alloy
