Engineered by Umarex to maintain peak performance and extend the lifespan of CO2-powered airguns and airsoft replicas, the 12g CO2 Valve Maintenance Capsules (item code 4.1683-2) offer an effortless, automated lubrication system. Each 12-gram capsule contains high-purity carbon dioxide combined with a precisely dosed special valve-lubricating oil.

During firing, the atomized oil coats the internal valve assembly, seal rings, O-rings, and moving internal parts. This process cleans carbon and dirt deposits, conditions rubber seals to prevent leaks, and ensures consistent firing pressure over time.
