The standard workhorse for general hydraulics, pneumatics, and fuel systems. It offers superb resistance to petroleum-based oils, greases, and hydraulic fluids, backed by excellent tensile strength and wear resistance.Specially included for applications exposed to dry heat, ozone, UV radiation, and weather aging. Silicone maintains its flexibility and sealing force at extreme thermal ceilings, making it ideal for food processing, automotive engine compartments, and high-temperature air lines where NBR would otherwise harden and crack.

The definitive operational advantage of utilizing a CFKS multi-size O-ring kit is the drastic reduction in diagnostic downtime and the elimination of single-size ordering bottlenecks. Maintenance technicians frequently encounter worn seals on imported machinery with unknown specification standards. Having a comprehensive kit removes the guesswork. During installation, the high elasticity of our NBR and Silicone rings allows them to be seated smoothly into internal or external grooves without specialized tools. Because our compounds resist permanent compression set, they deliver an extended service life, protecting your shafts, valves, and cylinders from fluid loss and external contamination.
