Component longevity in modern fluid power systems depends entirely on chemical and thermal compatibility. The DK Piston Seal is available in two distinct formulations:
NBR: The ideal choice for standard mineral-based hydraulic oils, grease, and water-glycol fluids, providing excellent abrasion resistance and mechanical toughness.
FKM: For demanding systems exposed to synthetic fluids, aggressive chemical media, and elevated temperatures. FKM effectively resists thermal degradation and hardening, ensuring the seal lip maintains its elasticity and critical radial force over prolonged operation.

A primary operational advantage of the bonded DK Piston Seal is its simplified installation profile. Unlike conventional multi-piece seals that require complex stretching or multi-stage assembly tools, the rigid metal-bonded housing of the DK seal allows it to be easily pressed directly onto the piston rod shoulder. This robust structural design eliminates the risk of lip inversion or tearing during assembly. Furthermore, the optimized lip contact geometry ensures a low-friction lifecycle, reducing energy consumption and preventing localized heat buildup to maximize the service interval of the entire cylinder.
