6 Pack  tube cap O-rings designed for Umarex Fusion and XS60C air rifles. 

These replacement O-rings are used on the degassing tube cap instead of the original orange O-rings provided with the gun. 

These upgraded O-rings are more resistant to swelling, blistering, and cracking compared to the factory ones.

These O-rings are made from a harder material that swells less and doesn't blister or crack as quickly.
