Piston FKM O-ring Viton AL-300

24mm, extremely low friction coefficient of 0.05μ, high temperature stable, 70a hardness.

Extremely stable at higher operating temperature which makes it great for high rps builds as piston o ring heats up during cycles. 

Probably overkill for most builds, you probably don't need it but its cool. 

BETA item - meaning we are currently in process of testing this item and we haven't ran enough time through it to wholeheartedly recommend it. However, this doesn't mean its a bad product it just means we are still testing.
