What is an O-Ring?. Seals and O-rings are used to join two parts of a machine, engine or other mechanical assemblies by filling the space between both parts, creating a filled and seal space in between. This seal prevents particle, vapour and fluid leakage which in turn protects and maintains pressure whilst keeping debris out, ensuring proper function and safety.
