O-Ring Groove Calculator Piston Seal

'Piston' styled O-ring grooves are commonly used static & dynamic O-ring sealing configurations. This page specifically concerns static (unmoving) and dynamic (moving) reciprocating Piston O-ring seals.

The purpose of the calculator below is to serve as a groove calculator for Piston Seal O-ring grooves using all AS568*, JIS, common metric, and custom O-ring sizes. 

* Please note that some AS568-0XX O-rings have atypical cross sections. Please see our General Groove Guide for more information, or feel free to get in touch with our engineers if you have any questions.
