DK 104

Model DK 104 is a compact single-acting seal for medium and high pressure hydraulic cylinders. The O-ring exerts uniform tension on the lip in the sealing areas, even when there is no pressure in the medium.
At the rear, it has a triangular section support ring that allows working at higher pressures; it avoids extrusion of the collar and allows a larger extrusion groove between the liner and the piston.
- Good extrusion behavior.
- Greater tightness at low pressures.
- Absorption of pressure peaks.
Part recommended for medium and high pressure mobile hydraulics.
