Question:

Rubber and metal have to be sealed before they are too strong

Rubber and metal have to be sealed before they are too strong

Answer:

Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.
The percentage difference between the first compression compression = original section diameter minus the trench size divided by the original O ring diameter O-ring compression is mainly depends on the material hardness and O-ring, O-ring if the hardness is 70 degrees, then the O-ring compression is equal to 20%. Of course, the lower the hardness of the O-ring, O-ring compression is greater, mainly used for low pressure places. Then the O-ring hardness increases the amount of compression of the O-ring is smaller, mainly used for high pressure, pressure resistance, resistance of small environment. And so on, the amount of compression can be any hardness O-ring you need.
