Rubber Metal Gasket

Main load gasket. The 1730-MF consists of a steel ring which

is surrounded on all sides by rubber. The steel ring is

therefore protectedfrom corrosion and media.

Vulcanisation guarantees a high level of adhesive strength

between the rubber and the steel ring.

Main load gasket. The 1730-MY has two stable sealing lips

on its internal sealing diameter and the same design as

1730-MF on its external diameter.

Main load gasket. The 1730-MO consists of a central

support ring and arubber sealing ring with integrally moulded

sealing lips. The central support ring is available in galvanised

and SS steel or Plastics.

Metal-to-metal contact gasket. 1730-OF in its standard form

consists of a galvanised and chromated metal support ring

and a rubber sealing ring with integrally moulded sealing lips.

The support ring is also available in SS steel or plastics.

In contrast to traditional gaskets, the rubber sealing ring in

the 1730-OF is in off load contact.

Any forces that are too high for the rubber sealing ring are

borne by the support ring. Very high internal pressures and

additional forces from the pipeline system can be permitted.

The 1730-OF combines all the advantages of a rubber

gasket with those of a metal gasket.

Metal-to-metal gasket The 1730-OC is essentially designed

in the same way as the 1730-OF. Except that the support

ring is made with layers of graphite. The metal core can be

made by Kammprofile shape. In normal use the rubber

sealing lip forms the primary seal. Under extreme thermal

loads.Such as during a fire, the support ring with graphite

layers provides the seal.
