O-ring seal

circularNBRPTFE

PTFE O-ring With characteristics of oil resistance, heat resistance as well as wear resistance, NBR is widely used to make sealing product. But it’s not suitable for resisting phosphate hydraulic oil and gear oil which with polar solvents. DESCRIPTION NBR With characteristics of oil resistance, heat resistance as well as wear resistance, NBR is widely used to make sealing product. But it’s not suitable for resisting phosphate hydraulic oil and gear oil which with polar solvents. - NBR is used in the manufacture of O ring, oil seal. It‘s suitable for general hydraulic and pneumatic sealing system. FKM shows excellent resistance to high temperature, acid-base and other chemicals, FKM withstands almost every hydraulic oil (including phosphate oil series), lubricating oil, gasoline and synthetic oil as well. - FKM applies to applications that request for resisting high temperature, chemicals and hydraulic oil based. It’s widely used in metallurgy, electric power and other industries. Silicone Silicone has features of good heat resistance, good cold resistance, and small compression permanent deformation, but the low mechanical strength - Silicone seals are appropriate for sealing food machinery and equipment and for super-speed rotary applications which under high and low temperature.
