DLSEALS Standard AS568 Series Silicone Rubber O Ring

Silicone/Rubber o ring

*Service Temperature
For Silicone the service temperatures are from -60 C to 225 C. Some special types can be used in extreme temperature up to 300 C and down to -100 C.

*Application
Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that need FDA approval for food handling equipment and appliances.

*Service Temperature
For NBR the service temperature can be designed from -55 C to 100 C or up to 130 C depending on differenacrylonitrile content and formula.

*Application
NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures.

FKM, (Fluorocarbon)
*Service Temperature
For general type fkm the service temperature is better limited to approximately from -26 C to 232 C in static applications, though the service temperature can arrive to 275 C at short time In dynamic applications, it is suitable between -15 C and 200 C.

*Application
Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemicals and weathering, it is usually applied in automotive, chemical processing, aerospace and many other industries.
