An o-ring seal is a doughnut-shaped mechanical gasket which sits in the groove between two or more parts in the assembly. Once compressed, the o-ring creates a seal at the interface between the two components. O-ring are used in static applications, such as in fluid or gas sealing applications, as well as in dynamic applications, such as in rotating pump shafts or hydraulic cylinder pistons. O-rings are among the most used seals used in machine design because of their low cost, ease of use and reliability. BSC is Australia’s largest distributor of o-rings.
