Static Seal, inside or outside sealing S 90

Product catalog summary
Overview: The document discusses the S 90 static seal, designed for larger diameter applications, and its interchangeability with O-Rings of 7 mm and 10 mm cord sizes. The S 90 is suitable for high-pressure environments and can be used without backrings, unlike conventional O-Rings.
Specifications: The S 90 seal is available for inside and outside sealing and is butt-joint vulcanized to the required diameter. It is applicable for diameters starting from approximately 250 mm for 7 mm cord size and 400 mm for 10 mm cord size.
Materials and Application Range: The document specifies the materials used and the application range for the S 90 seal, emphasizing its use in static sealing for O-Ring grooves.
Design Hints and Surface Finish: The document provides design hints, noting that the sealing lips should face the pressure side, with the shorter lip on the sliding surface. Surface finish requirements are also detailed.
Fitting Instructions: The S 90 is fitted similarly to an O-Ring, with specific attention to the orientation of the sealing lips.
Order Example: Examples are provided for ordering the standard version of the S 90 seal, with specifications for both outside and inside sealing applications.
Design Table: A design table is included, detailing the groove width and depth for different cord sizes and diameters.

Static Seal, inside or outside sealing S 90-1

Statische Abdichtung, innen- oder außendichtend Static Seal, inside or outside sealing S 90 Statische Abdichtung, innen- oder außendichtend Static Seal, inside or outside sealing Um den Anforderungen von statischen Abdichtungen größerer Durchmesser gerecht zu werden, wurde das Profil S 90 entwickelt. Der Nutring S 90 ist austauschbar gegen einen O-Ring der Schnurstärke 7 mm bzw. 10 mm. In order to meet with the needs of static sealing of larger diameters the S 90 profile has been developed. The S 90 is interchangeable with an O-Ring of 7 or 10 mm cord size. Durch seine kompakte Bauweise und seine Dichtlippengeometrie ist der S 90 auch bei hohen Drücken einsetzbar. Er überbrückt dabei eine mögliche Rohraufweitung. Die spezielle Geometrie dieser Dichtung gestattet in den meisten Anwendungsfällen einen Verzicht auf einen Backring, der bei einem O-Ring notwendig wäre. Due to its compact nature and sealing lip geometry, the S 90 can be applied even at high pressures, where it can compensate for cylinder tube expansion. In most cases, the geometry of the seal allows omission of backrings that would otherwise be necessary with conventional O-Rings. Der S 90 ist innen- und außendichtend lieferbar und wird auf den erforderlichen Durchmesser stoßvulkanisiert. Als Ersatz für die O-Ring-Schnurstärke 10 mm ist der S 90 ab ca. 400 mm Durchmesser einsetzbar, für die O-Ring-Schnurstärke 7 mm bereits ab circa 250 mm Durchmesser. The S 90 is available as inside and outside sealing and is butt-joint vulcanized to the required diameter. As replacement for O-rings of 10 mm cord size the S 90 is available from diameters of approx. 400 mm and for O-rings of 7 mm cord size it is available from diameters of approx. 250 mm. 283
