Formulated primarily in High-Density NBR with optional FKM variants, the DK seal compound is chosen based on specific fluid media and temperature dynamics. Premium NBR provides excellent resistance to petroleum-based oils, hydraulic fluids, and grease, operating reliably across standard industrial thermal cycles. For extreme chemical exposure or elevated temperature spikes, FKM offers superior cross-linking stability against synthetic oils and aggressive media. Both elastomers are compound-blended with anti-wear agents to minimize lip degradation and prevent early shaft grooving.

Designed for straightforward, press-fit installation into standard housing bores, the DK Skeleton Oil Seal significantly minimizes downtime during maintenance overhauls. The rigid steel frame allows uniform press fitting without tilting or damaging the sealing lip during assembly. Thanks to low-friction compound engineering and optimized lip geometry, the seal generates minimal break-away torque and thermal buildup during initial run-in. This low-wear operational profile extends maintenance intervals and protects expensive shafts from premature fretting wear.
