Indications for choosing the seal

Some indications for choosing the seal:

EPDM - Advantages: It has excellent resistance to heat, ozone and sunlight, very good flexibility at low temperatures, good resistance to alkalis, acids, oxygenated solvents and very good resistance to water and steam. Limits: poor resistance to oil, gasoline and all hydrocarbon-based solvents.

Maximum continuous operating temperature -20 /+100°C.

NBR - Advantages: excellent resistance to oil and mineral lubricants, good resistance to gasoline, alkalis, acids, hydrocarbon-based solvents. Limits: poor resistance to ozone and to aromatic hydrocarbons

Maximum continuous operating temperature -20 /+90°C.

FKM (Viton®) - Advantages: excellent resistance to ozone and sunlight, lubricant oils and hydrocarbons. Poor flexibility at lower temperatures. Good resistance to alkalis, acids and hot water. Not suitable for steam.

Maximum continuous operating temperature -20/+ 200ºC.

PTFE - Advantages: excellent resistance to a wide range of media materials.

Maximum continuous operating temperature -20/+ 220ºC.
