Rubber steel gasket

A rubber steel gasket fits itself to the surface of the flange. Also when the flange mis-matches, or when there are minor damages to the flange. The rubber steel gasket has a steel insert and is available in three types. We are happy to advise you about the possibilities. 

The rubber steel lined gasket is suitable for gas, water, and drinking water applications. For example, in water companies and GRP (pipeline) systems. The sealing is also widely applied in the (petro) chemical industry, the pharmaceutical industry, steel factories and power plants.

Properties of the rubber steel gasket

There is an extremely strong bond between the rubber and steel in the rubber steel lined gasket. Separation of the parts is impossible. In the sealing the benefits of the different components and materials are combined:

  • High surface pressures are absorbed by the rigid ‘body’ of the seal.
  • The flat steel ring (corrosion resistant) easily absorbs pressure from the inside out.
  • The seal can easily be mounted, because the seal is self-centering.
  • The sealing shapes itself to the surface of the flange, even with minor damages.

Rubber steel gasket types

Ridderflex supplies three various types of rubber steel lined gaskets:

With internal o-ringThis gasket type seals perfectly, even at lower (surface) pressures. Inconsistencies and grooves are compensated. Because of the internal o-ring this type seals better, and there is less chance of contamination of the product. Rubber steel gaskets with internal o-rings are therefore mainly used for drinking water applications.
Without internal o-ringThis gasket type seals perfectly, even at lower (surface) pressures. Inconsistencies and grooves are compensated. The internal o-ring lacks in this type, this means that there is a risk of dirt between the two flanges.
Wedge shapeThe wedge shape excels in solving alignment problems and gaps in the installation. The “shell” shape provides the posibility to resolve unequal distances from 0 ° up to 8 ° within the flange.

Rubber steel gasket in various grades

We supply rubber steel gaskets in various rubber grades, such as: EPDM, NBR, Neoprene, Hypalon® (CSM), Viton®(FKM) and Butyl. The application determines the type of material of the product. Our specialists are happy to help you composing the right gasket.
