EPDM 70 Shore A

EPDM - Ethylene propylene rubber (for glycol-based brake fluids)

O'rings, also known as rubber rings and sealing rings are the most frequently used type of seal. It is due to the fact that installation of O'rings is very easy and that they require little space. If the selected material the design of the groove are suitable, sealing based on O'ring may play its role for a longer time (provided that the permitted temperature ranges, etc. are adhered to). The most commonly used materials for the manufacture of O'rings are NBR (nitrile butadiene rubber), FPM (fluoroelastomer), MVQ (methyl vinyl silicone rubber), EPDM (ethylene propylene diene monomer (M-class) rubber), etc. Among the less used ones is e.g. CR (chloroprene rubber).
