A Back Up Ring is a rigid component that maintains an elastomeric seal’s shape and correct position. While not seals themselves, backup rings are commonly paired with O-rings, lip seals, and reciprocating shaft seals to prevent extrusion through gaps under pressure. For optimal protection, it is often recommended to use two backup rings—one above and one below the sealing ring
Back Up Rings come in two constructions: solid and spiral (overlapping and coiled). The spiral design creates multiple contact points, offering enhanced support and reliability
At Excellent Engineering and Allied Services, we provide backup rings in a wide array of sizes, hardness levels, compression sets, and tolerances, suitable for various elastomers
An O- Ring is a type of mechanical gasket commonly used in sealing applications to prevent the leakage of fluids or gases between two mating surfaces. It is typically made from elastomeric materials such as nitrile rubber, silicone
The Green PU Back Up Ring (ST 08) is a specialized sealing component designed to complement and enhance the performance of hydraulic seals, particularly in high-pressure and demanding applications
The Green PU Back Up Ring (ST 09) is a specialized sealing component designed to work in conjunction with O-rings and other seals to enhance sealing performance and reliability in hydraulic and pneumatic systems
