O Rings

Perfluoroelastomer (FFKM) O Rings

Perfluoroelastomer O Rings exhibit the highest level of thermal and chemical resistance coupled with the highest temperature resistance. Perfluoroelastomer (FFKM) O Rings are extensively used in Oil & Gas, Semiconductor, Chemical Process Industries.

Aflas ® O Rings
AFLAS O Rings have excellent chemical resistance over a wide variety of all media and hence find their application in Chemicals, Food Processing Industries and Nuclear Plants. Due to their high temperature resistance of up to 230° C and lower costs compared to Perfluoroelastomers, Aflas O Rings are being used on a large scale.
Fluorosilicone (FVMQ) O Rings

Fluorosilicone O Rings exhibit excellent resistance to dilute acids, alkalis, animal & vegetable oils, ozone, oxidation, weather, water, high temperature & most importantly are inflammable.

Hypalon ® O Rings (Chlorosulfonated Polyethylene)

HYPALON O Rings have excellent resistance to dilute acids, alcohols, ozone, oxidation, weather & sunlight. HYPALON O Rings are generally suited for static applications as their compression set resistance being limited; it is a deterring factor for dynamic applications.
