The P-V Polyseal Fluorocarbon U-Seal combines the proven Polyseal design with genuine DuPont™ Viton® fluorocarbon for demanding hydraulic applications. A four-lobed expander ring maintains consistent sealing force across the operating pressure range while enhancing low-pressure sealing performance to help prevent leakage ("weeping"). Viton® offers excellent compatibility with a wide range of fluids and continuous operating temperatures from -20°F to +400°F, making it ideal for high-temperature and chemically demanding environments.


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.
