Rod & Piston (Static) Design Guide
'Rod' & 'Piston' styled O-ring grooves are commonly used O-ring sealing configurations. This page specifically concerns static (unmoving) Rod & Piston O-ring seals.
The purpose of the tables below are to serve as a design guide for static 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 about O-rings, gaskets, & custom molded parts.
Surface Finish X: 32 RMS for liquids, 16 RMS for vacuum and gases
