• Ethylene - Propylene EPDM (ethylene/propylene) seals

    Usable at higher temperatures than NBR (excellent for phosphate ester-type fluids, for example, but not a good for petroleum-type fluids).
    Their temperature range is much wider than that of NBR. Based on these characteristics, this material has been used to replace butyl.

    They are used as O-rings in solenoid valves and steam valves thanks to their resistance to residual deformation after compression. They generally adapt to most photographic products and to many chemical solutions.

    They are used for applications requiring temperatures higher than those covered by NBR, such as to carry hot water and steam. They are extremely compatible but their greatest disadvantage is that they cannot be used in the presence of petroleum-based for heavily contaminated (such as lubricated air) fluids. Their temperatures of use are -20°C to +180°C.
