MBD Piston Rod Seal

The MBD piston rod seal is an advanced lip seal with two sealing lips and an extrusion-resistant backup ring. It maintains extra lubrication to prevent dry friction and wear, extending the seal's lifespan. In some cases, it can replace expensive series seals, providing effective sealing even when rubber or fabric-reinforced rubber falls short. It is mainly used for sealing piston rods and plungers in heavy-duty machinery and static pressure systems.
