Product Description
A hydraulic PU (polyurethane) seal is a component made from a versatile material that prevents hydraulic fluid from leaking in machinery like hydraulic cylinders. These seals offer a combination of rubber's flexibility with the toughness and durability of plastic, featuring high abrasion and tear resistance. They are essential for maintaining system pressure, are designed for dynamic applications such as reciprocating rods or pistons, and can handle high pressures and wide temperature ranges
