An O-ring is a type of circular seal available in a wide range of sizes and diameters. The primary purpose of an O-ring is to seal in areas where high pressure is not present, but also where it is subjected to high pressure. Under high pressure, an O-ring adopts fluid-like properties (surface tension, plasticity, etc.), providing excellent sealing properties.

A back-up ring is a rigid ring, usually made of plastic, that protects O-rings from damage caused by the high pressure and temperature inside a hydraulic system during operation. A back-up ring (also known as a backup ring) is a ring whose primary function is to prevent the O-ring from being forced into the gap between the sealing surfaces and to protect the seal from deformation, which can occur when the seal is subjected to high pressure and temperature. When pressure acts on the O-ring from two directions, a back-up ring is used on both sides of the O-ring.

An O-ring seal is also resistant to high operating temperatures, and the selection of the appropriate one depends on its intended use and the material from which it is made. O-ring seals in high-pressure devices require the use of a special back-up ring.
