AS-021 23.52*1.78 O-Ring: Ensuring the integrity of the PISTELLE X-68 Gen.2 main body

The AS-021 O-Ring is designed for joints that are typically not dynamically stressed like moving pistons, but where it is necessary to prevent pressure leaks in voluminous chambers. The ring material must have excellent memory and resistance to reliably fill the sealing groove and maintain pressure over a long period after the cap is tightened. Failure of this ring can lead to a rapid drop in operating pressure.

Dynamic vs. Static Load

Even if the O-Ring is in a primarily static position, mechanical damage or deformation may occur due to repeated assembly and disassembly of the firearm. Before installation, it is recommended to lightly lubricate the ring and inspect the groove to extend its lifespan.
