Selecting the correct elastomer is critical for seal longevity. Our NBR compounds offer excellent resistance to petroleum-based hydraulic fluids and are the industry standard for general industrial machinery operating in moderate temperatures. For environments involving synthetic fluids, steam, or temperatures exceeding 120°C, our FKM variants provide superior thermal stability and chemical inertness. Both materials are processed to ensure high tensile strength and compression set resistance, preventing the seal from flattening or hardening over time.

One of the primary operational advantages of the CFKS OK Seal is its split-design compatibility, which significantly simplifies the assembly process. While it provides a heavy-duty seal, the material’s low-friction coefficient reduces the “stick-slip” effect during startup, protecting the cylinder’s inner wall from scoring. Maintenance requirements are minimal; the seal’s high wear resistance means longer periods between overhauls. When replacement is necessary, the geometry allows for a straightforward snap-in installation, reducing machine downtime and labor costs.
