Item Information

Parker's 70 durometer black EPDM, E0803-70, 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.

Temperature range: -70°F to 250°F (-57°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
• Phosphate-ester based hydraulic fluids (HFD-R)
• Silicone oil and grease
• Many polar solvents (alcohols, ketones, esters)
