What is BS 4518 standard

British Standard metric sizes are identified by Standard BS 4518, which was published by the British Standards Institution. The size code for these O-Rings is a four-digit number followed by a hyphen and two numbers that represent the O-Ring Cross Section, also in tenths of a millimeter.

For example, fluorosilicone 0111-16 is an BS4518 standard fluorosilicone O ring with inner diameter 11.1mm and cross section 1.6mm.

On the basis of maintaining the excellent properties of silicone materials such as heat resistance, cold resistance, high voltage resistance and weather aging resistance, BS4518 standard fluorosilicone O ring has excellent hydrogen resistant solvents, oil resistance, acid and alkaline resistance and lower surface performance due to the introduction of fluorine containing groups.
