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 Standard profile features equal seal height and cross section, creating a square seal geometry.It utilizes the Type D sealing lip, making it the standard choice for general-purpose hydraulic sealing applications.
