Gasmate Power Fuel Iso-Butane Cartridges make enjoying the outdoors simple and easy. Featuring Twin Safety Devices - Rim Vent Release and Triple Seamed Rim Technology.
Rim Vent Release (RVR)™ will activate in an over-pressure situation. A controlled release of pressure means you can safely extinguish any flame or move away to a safe distance.
Triple Seamed Rim (TSR) holds the cartridge tighter and longer to allow the RVR™ device to activate securely.
