Rod & Piston (Dynamic) Design Guide

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


The purpose of the tables below are to serve as a design guide for dynamic reciprocating Rod & Piston O-ring grooves using AS568 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.
