HPSI

The H O-Ring Loaded U-Seal is molded from tough, abrasion-resistant polyurethane for reliable hydraulic sealing in dynamic applications. An integrated O-ring expander maintains consistent sealing force across the operating pressure range while enhancing low-pressure sealing performance to help prevent leakage.


The Deep profile uses the same Type D sealing lip as the Standard profile but has a greater seal height than cross section, resulting in a rectangular geometry. This profile is designed for applications requiring a deeper seal configuration.
