Zurcon® Glyd Ring® D

Cool under pressure

By combining a new seal design and specifically designed material, Zurcon® Glyd Ring® D removes the risk of blow-by effects under high pressure and provides unrivalled durability in mobile hydraulic applications.

The Zurcon® Glyd Ring® D has been specifically designed for use in hydraulic sealing applications subject to increasingly higher pressures. Machines, equipment and motors fitted with hydraulic cylinders are becoming more powerful, meaning that cylinders are subject to increasingly higher pressures and temperatures.

The new design combines a closed oil reservoir, a two-step sealing area, rounded profile and elastomer O-Ring to enhance sealing performance and prevent blow-by.

When under increasing pressure, the O-Ring and seal body transmit pressure along the sealing surface, assuring sealing efficiency at all pressure levels. As the pressure rises, the contact force against the mating surface increases, ensuring optimum sealability

When the seal is pressure loaded, the seal body rotates, improving contact pressure on the sealing edges. If the pressure changes direction, then the seal returns to its original position – avoiding blow-by effects.

The new Zurcon® Z13 polyurethane material displays excellent mechanical and elastic properties and is compatible with a variety of hydraulic, mineral, synthetic and water-based fluids. In addition, this material offers excellent wear, extrusion and hydrolysis resistance and can be used in cylinders with lower quality inner walls.
