POWERgasket DRS-2 - Rubber metal gaskets

The POWERgasket DRS-2 rubber metal seal is the next step in the development of these types of seals. It has two stable sealing tongues - blades on the inner diameter, which ensure better functionality of the seal . Therefore, the POWERgasket DRS-2 rubber seal is also suitable for plastic flange connections where high tightening torques cannot be used.

Special benefits and features

1. Secure sealing even at the lowest tightening torques thanks to the special shape of the sealing profile.
2. High stability during installation and operation.
3. Greater tightness due to the "opening effect" of the sealing lips under internal pressure loads.
4. There is no exceeding of the specific pressure or relaxation of the flexible sealing lips, as can occur with rubber-metal seals with an O-ring seal or a wedge.
5. Optimal compensation of flange irregularities with flexible sealing edges.
6. Safe compensation of small flange deformations.

Application

1. Plastic and steel flanges.
2. Sealing of vacuum piping systems.
3. Seals suitable for the chemical, water and gas industries.
4. Suitable as a seal for rotating flanges.

Advantages over punched seals

1. Higher quality rubber with SHORE 85 hardness.
   • Thanks to the higher hardness of the seal, easier installation when inserting between flanges with large pipe diameters - up to DN 2,000 mm.
   • Longer seal life due to higher hardness.
2. Higher rubber density due to higher temperature and pressure during vulcanization.
3. Each seal is marked with a print with the material and the manufacturer's mark.
