The seal set is designed for heavy duty hydraulic applications. Product advantages The can be used where a piston has pressure on both sides and is designed especially for large diameters Very high resistance to pressure Design prevents twisting Very good protection against extrusion High resistance to abrasion Good thermal conductivity Low friction, free of stick-slip High contact pressure due to elastomer profile ring.
