Back-up rings are used with sealing rings and seals for static and dynamic seals. They prevent extrusion of the sealing ring or seal when it is subjected to high pressure. The backup ring should be used on the opposite side of the seal pressure.
For seals that are subjected to pressure on both sides, two protective rings should be used, one on each side of the sealing ring or seals.

Own production and a large selection of materials allow us to manufacture seals of any complexity and any size from 4mm to 500mm. during a process of the manufacture of seals the method of turning on CNC equipment blanks of various materials is used.
