Special Features: Operational pressure : Up to 200 MPa (2000 bar) Temperature : depending on material -60 °C to + 280 °C Back-up rings are used with static as well dynamic applications. However, they have no sealing function. Extrusion of O-rings or X-Ring under the influence of presssure should be avoided with the back-up ring. Manufacture of back-up rings in various materials is possible. Simple groove geometry Easy assembly Multitude of materials of construction Individual sizes possible Bridging of large sealing gaps High areas of temperature Neutral to temperature fluctuations Back-up Ring 267
