Parker's ethylene propylene rubber (EPM, EPR, EPDM) O-rings are compatible with solvents and other chemicals.
Parker's 90 durometer black EPDM, E0652-90, is a terpolymer of ethylene and propylene with a diene third monomer used for cross linking. This is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. E0652-90 is the common material for EPDM back up rings.
Temperature range: -60°F to 250°F (-51°C to 121°C)
Chemical resistance
• Hot water and steam up to 300°F (149°C)
• Glycol based brake fluids (Dot 3 & 4) and silicone-based brake fluids (Dot 5) up to 300°F (149°C)
• Many organic and inorganic acids
• Cleaning agents, sodium and potassium alkalis
