Hydraulic Piston Seals are there to prevent that fluids do not leak at the cylinder head as the pressure pushes the piston down. The hydraulic piston seals come in the form of single acting or double acting piston seals to provide the optimum seal for the cylinder being used.
A hydraulic piston seal or piston ring is typically made from PTFE or polyurethane, a rubber/fabric composite or polyester elastomer making it highly resistant to wear and can tolerate extremes in temperature.
Mourne Hydraulics provide a wide range of hydraulic piston seals of high quality as standard.
