Le conseil de l'expert

How to read the reference of an O-ring?

Example:
OR-40X3-NBR90
Where
OR = product type (O-ring or O-ring seal)
40X3 = inside diameter X thickness
NBR = matter
90 = shore hardness

Shore hardness is a material hardness scale, usually between 70 and 90 for O-rings. The higher the number, the harder the material.

What does the number mean at the end of the reference?

This is the indication of shore hardness. Shore hardness is a material hardness scale, usually between 70 and 90 for O-rings. The higher the number, the harder the material.

Difference between NBR, FPM, EPDM, MVQ?

These are the different types of rubber. Each material will be more or less suitable for a use. Refer to the following information: FOR OILS NBR = Nitrile = Butadiene rubber - Acrylonitrile
        from -30°C to +120°C
FPM = Viton = Fluorinated Rubber
        from -20°C to +200°C
MVQ = Silicone rubber
        from -50°C to +210°C
FOR HYDROCARBONS NBR = Nitrile = Butadiene rubber - Acrylonitrile
        from -30°C to +120°C
FPM = Viton = Fluorinated Rubber
        from -20°C to +200°C
FOR BRAKE FLUID EPDM = Ethylene Rubber - Propylene - Diene
        from -40°C to +150°C
FOR WATER EPDM = Ethylene Rubber - Propylene - Diene
        from -40°C to +150°C
MVQ = Silicone rubber
        from -50°C to +210°C CAUTION: never water above 80 ° C

How to choose the size of my O-ring?

An O-ring should not, in general, be too stretched. It is therefore preferable to take a dimension as close as possible to the groove diameter, if applicable.
