Material selection is critical for sealing integrity, and the CFKS series offers versatile compounding options tailored to specific operating media. FKM is selected for aggressive chemical resistance and high-temperature performance, maintaining elasticity and sealing force in environments exposed to synthetic oils, hydraulic fluids, and thermal extremes ranging up to 220°C. Alternatively, NBR provides excellent mechanical durability and resistance to standard mineral oils and greases at moderate temperatures, ensuring robust abrasion resistance and long-term dimensional stability.

Proper installation is vital to maximize the service life of the metal-cased oil seal and prevent premature lip damage. Installers should use a cylindrical pressing tool that applies uniform force directly over the outer metal rim to avoid distorting the casing or damaging the elastomer lip. Before assembly, lightly lubricating the shaft and seal lip with compatible fluid minimizes initial startup friction. Because of the durable stainless steel housing and high-wear FKM compound, the assembly requires minimal maintenance intervention, significantly lowering total lifecycle operational costs.
