Hydraulic seals, the best protection against leakage of liquids or gases
Hydraulic seals are used in hydraulic and pneumatic cylinder pistons. They are made with different profiles and materials and protect the cylinder head against possible leakage of liquids or gases. Hydraulic seals can be single or double effect, according to the direction of the pressure generated in the cylinder.
Below you will find more information about the main range of hydraulic seals: type, profile, material, as well as the pressure, temperature and speed that these seals support. In our stock you will find piston seals (PK3 and PK4), u-rings (UN, D2 and D3) and wiper seals (MW, ME1 and ME2).
