Product Description
The HOD Piston Seal is a four-piece combination seal used in heavy-duty hydraulic cylinders. The primary PTFE seal is made of low-friction materials which is perfect for the high-speed and high pressure hydraulic cylinder application. The HOD Piston Seal is a double acting seal and is supported by nylon back-up rings on either side to allow sealing and protect the main PTFE profile from high pressures on both sides of the piston. Together, this combination seal can withstand pressures of up to 50Mpa. The HOD Piston Seal is mostly used in mining equipment, construction machinery and high-speed hydraulic cylinders.
