Seal Informations
| 1) Dimensional stability of the O-Ring improves the sealing force and increases the service life. Nylons are frequently used as replacements for bronze, brass, aluminum, steel, and other metals, as well as other plastics, wood, and rubber. | |||||||
| 2) Nylons offer extremely good wear resistance, coupled with high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, nylons can withstand sustained contact with a wide variety of chemicals, alkalies, dilute acids or oxidizing agents. |

Back-up Ring Application
Back-up Rings have no intended sealing function. Instead, as the name indicates they are supporting elements made with extrusion-resistant materials which generally have a rectangular cross section. They are installed in a groove together with an elastomeric sealing element preferably with a corresponding O-Ring in static applications. Due to the tight fit of the Back-up Ring in the housing, they prevent extrusion of the pressurized elastomeric sealing element into the sealing gap.
Used in a variety of applications such as with the use of O-Rings in high pressure applications, use of O-Ring materials with a low hardness, compensation of radial sealing gaps, use for internal and external sealing applications, reciprocating and rotating movements possible, compensation for large temperature fluctuations, static and dynamic applications.
