UMAREX FUSION AND XS60C TUBE CAP O RING KIT

Umarex Fusion and XS60C air rifles This is a pack of 6 tube cap O'rings for the Umarex Fusion and XS60C air rifles. These are for use on the degassing tube cap as replacements for the orange O ring supplied with the gun. These black O'rings swell less and resist blistering and cracking much better than the factory O rings. These O'rings use a different, harder, O ring that swells much less, doesn’t blister and crack as quick with use. Yes, it still swells in use, so simply roll off the swelled O'ring, roll on the new one, gas up your Fusion or S60C and keep shooting! The swelled O'ring will return to size and can be used again by the time you need to reload with Powerlets. So why not fit O'rings that don’t swell at all? The reason is that such O'rings - typically hard urethane ones - will not allow any current tube cap design to be fitted into the gas tube of the Umarex Fusion or XS60C air rifles. This is due to the design of the main gas tube itself, which will not allow hard O'rings to be pushed into the end of the tube - that’s why the factory supplies those problematic soft O rings in the first place!
