What is O-ring?
O-ring is mainly used in fluid static application.(For example, water oil, air chemicals solvent,etc.) Temperature range is from -20°C~320°C. The pressure in static application should be less than 20Mpa. Sometimes it is also used in dynamic application and semi-conductor vacuum seal with the pressure less than 5Mpa.
O rings are produced in the following materials:
Nitrile (NBR or Buna-N)
HNBR (Hydrogenated Nitrile)
FKM (Viton ®)
FFKM (Kalrez ®)
Polyurethaan (AU, EU)
◪ Maximum Pressure:5Mpa
◪ Model Number: FFKM O-RING

FFKM/FFPM rubber is the material with the best high temperature resistance and chemical solvent resistance among all elastomer sealing materials. In general rubber, fluorine rubber can not reach the resistance to chemicals and corrosive media such as strong acids, strong alkalis, ketones, ethers, alcohols, esters, aldehydes, hydrocarbons, nitrogen compounds and amino compounds.
According to different working environment and temperature, perfluoroether can be widely used in petrochemical industry, chemical industry, pharmaceutical industry, solvent equipment, aerospace equipment, nuclear energy industry, especially in the photolithography process, chemical etching and chemical cleaning in the semiconductor production process In extremely harsh environments, which require extremely high thermal stability and chemical resistance, perfluoroether can play the best role.
