Ethylene Propylene 70 Durometer O-Ring, General Purpose, Automotive Coolant (E0803-70)
Brand: Parker HannifinParker's ethylene propylene rubber (EPM, EPR, EPDM) O-rings are compatible with solvents and other chemicals.
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.
