GKDF Combination Seal

The GKDF combination seal consists of a sealing ring, an elastic ring, and two guide sleeves. The guide sleeves provide positioning and guidance, while the elastic ring applies pre-compression force and compensates for the wear of the sealing ring. The sealing ring forms a fit with the cylinder bore, generating a sealing effect on the mating surfaces. It is suitable for piston seals in hydraulic cylinders and provides bi-directional sealing performance.
