U-Seals and U-Rings

U-Rings and Rod Seals are available in a variety of sizes and materials

The function of a U-Ring or U-Seal is to provide a pressure seal in either a static or dynamic application. They can be symmetrical in section or assymetrical depending on whether they are piston or rod working. They can be energised with meander springs or O rings in the groove of the seal, and have additional wiper or scraper features added. Consideration needs to be given to the environment expected, and the friction losses acceptable. View our standard profiles for general guidance and please contact us to discuss your specific requirements so that we may advise on the best solution for the application.
