KN Rubber-Steel gasket 9107/KN

The KN rubber-steel gasket 9107/KN consists of a metal support ring and a speciallymolded, replaceable elastomer ring which is located in the force shunt after fitting. The support ring also acts as a centering ring and force limiter. It thus both absorbs the bolt forces needed for high pressures and protects the rubber seal against overcompression.

Notes:

With coated flanges, we recommend selecting the outer diameter of the coating so that the sealing lip on the atmospheric side lies in the steel part. If necessary, discuss the dimensions with your EagleBurgmann contact.

Forms of supply:
  • Standard dimensions as defined in the EagleBurgmann in-house standard for DIN flanges or for flanges to ANSI B16.5 and MSS SP-4.4
