Specifications

Profile DK 143 is a low-friction seal for double-acting cylinders in medium and heavy hydraulics.
It consists of a triangular section slip ring energized by a DFL 102 seal (rectangular section) with greater interference and stability in the groove than an O-ring.
- The rectangular section joint cannot twist on itself.
- Good dynamic and static sealing.
- Standardized housings according to ISO 7425.
The slip ring is machined in polyurethane and the DFL 102 seal in low remanent deformation elastomer. See materials section.
