Steel and Rubber Gaskets: Efficient and Durable Sealing
Steel and rubber gaskets offer excellent value for money by reducing the need for inventory and allowing for reuse. Their design combines a rigid steel core with a vulcanized rubber coating, ensuring extreme adhesion between the two materials. Thanks to this construction, even under high stress, the gasket maintains its integrity without displacement or separation.
The R-ST model, widely used in industrial applications, is characterized by its structural stability, even in large diameters, and its ease of installation. On the other hand, the R-ST-O/IR version incorporates a lens-shaped base body with an O-ring, which eliminates the need to machine grooves in the flanges, optimizing costs and installation time.
Benefits of Steel and Rubber Gaskets
- Sealing efficiency even with low tightening torques.
- Compensation of irregularities on the surface of the flanges.
- They allow the use of flanges and bolts with lower structural requirements.
- Ability to absorb angular deviations, offering greater flexibility than flat gaskets.
Available Lining Materials
Steel and rubber gaskets can be manufactured with different types of elastomers depending on the specific application:
- NBR (Nitrile): Excellent resistance to oils and fuels.
- EPDM: High resistance to ozone, UV radiation and drinking water.
- CSM (Hypalon): Suitable for applications with aggressive chemicals.
- FPM (Viton): Superior resistance to high temperatures and aggressive chemicals.
- Other materials available on request according to customer needs.
Key Features
- High level of tightness with low load on bolts.
- Adaptable sealing surface, ideal for compensating for irregularities in flanges.
- Steel insert prevents displacement or crushing of the gasket.
Applications and Uses
Steel and rubber gaskets are widely used in various industries and piping systems, such as:
- Gas and water supply systems
- Rubber, plastic and GRP (Fiberglass Reinforced Polyester) flanges
- Pipes operating under vacuum conditions
- Enameled surfaces on pipes and equipment
These gaskets represent a safe, efficient and easy-to-install solution for a wide range of industrial applications.
