Kalrez® o ring

They are distinguished by universal chemical resistance and high temperature resistance (periodically up to 350°C), while retaining the elasticity of the rubber. These unique features make Kalrez's oringi® suitable in places where rubber components are exposed to difficult thermal and chemical conditions. Importantly, these oringi are not susceptible to swelling, which is the most common cause of sealing failure. Thanks to these advantages,  FFKM oringi  (trade name Kalrez®) is especially recommended for places where they are exposed to advanced chemicals, very high temperature or low. The temperature range for these orings is -46 °C 326°C.

These are orings designed for the highest temperatures. Oringi FFKM are used e.g. aerospace, petrochemical and analytical and measurement equipment. Their durability and low permeability allow to extend the life of pumps, valves or mechanical seals. They are doing great in static and dynamic applications and are used especially where device reliability is a priority.
