O-rings are circular-shaped seals
that are used as chokers to prevent air or fluid flow in on out of defined space parameters. O-rings are constructed with different types of materials that have various tolerance, size, and hardness. They block a potential pathway that fluids may use to escape. They are inserted into grooves, and can they seal pathways by squeezing the O-ring. The memory of the O-ring or flexibility allows the ring to work in low or no pressure conditions. Pressure applied to the system pushes the O-rings against the wall of the groove in the opposite direction to that of the pressure. This, in turn, forces the seal to expand in a perpendicular direction to the direction of the pressure and sealing the opening. The size of O-ring is determined by its inside diameter and cross-section or width. Many O-rings are made of rubber with the exception of plastic and metal elastomers. They are used in cars, underwater cameras and SCUBA diving air regulators, dental implants, and paintballing.When it comes to matters maintenance, repairs, and operations, talk to the experts at MRO Supply.
