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 Type B profile shares the same rectangular dimensions as the Deep profile but features a Type B beveled sealing lip. The beveled lip provides improved oil film breaking while retaining the deeper profile geometry.
