'Face Seal' styled O-ring grooves are some of the most commonly used O-ring sealing configurations due to their simplicity and ease of assembly. 

The purpose of the calculator below is to serve as a groove calculator for Face 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.
