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.

Description

This seal material NBR, can be used at temperatures ranging from - 30 C to + 110 C.
The seals NBR material are resilient oils and greases, aliphatic solvents, dilute acids and bases, petroleum products (hydrocarbons), and have good gas impermeability, and poor resistance to ketone solvents, strong acids and atmospheric agents, hydraulic fluids flammable, and brake fluids.
The seals NBR material are resistant to tensile, flexural, and poor resistance to tearing.
