A back-up ring is a rigid ring, usually made of plastic, that protects O-ring seals from damage caused by high pressure and temperature inside the hydraulic system during operation. A back-up ring , Back-up ring (from English) is a ring whose main task is to prevent the O-ring from being pressed into the gap between the sealed surfaces and protects the seal from changing shape, which is possible when the seal is subjected to high pressure and temperature. In the case when the pressure acts on the O-ring from two directions, we use a back-up ring on both sides of the O-ring seal.

A sealing ring with a circular cross-section ( o-ring ) is a type of seal in the shape of a circle and comes in many sizes and different diameters. The main task of the o-ring seal is to seal in places where there is no high pressure, but also subjected to high pressure. Under the influence of high pressure, the o-ring seal takes on properties similar to liquids (surface tension, plasticity, etc.), which gives very good sealing properties. The o-ring seal is also resistant to high temperature during operation and the selection of the right one depends on its purpose and the material from which it was made. The o-ring seal in devices operating under high pressure requires the use of a special support ring.
