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 FOR MORE DETAILS ON THE MATERIALS, THEIR STRENGTHS AND LIMITS OF USE, REFER TO THE COMPLETE DESCRIPTION ON THE SEALED SEARCH PAGEHow 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.
