SD 104

Model DS 104 is a compact single-acting seal for medium and high pressure hydraulic cylinders. The O-ring exerts a 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 the extrusion of the collar and allows a larger extrusion slot between the sleeve and the stem.
Part recommended for medium and high pressure mobile hydraulics.
- Good extrusion behavior.
- Greater sealing even without pressure in the medium.
- Absorption of pressure peaks.
Can be machined in polyurethane and elastomers. See materials section.
