✦ Synopsis

Lammon Gasket Company, a division of Mascotech Incorporated, has developed an antistick substance for its corrugated metal graphite gaskets, which greatly simplifies the removal of gaskets from flange joints.

Corrugated metal graphite gaskets are ideally suited for flanged applications, as they provide good sealing integrity at relatively low gasket stresses.

Unfortunately, the graphite coating can become bonded to the flange during normal operation. This in turn makes gasket removal during routine maintenance difficult and can lead to damage to the flange facing through brushing or scraping.

However, Lammon Gasket has developed an anti-stick treatment that prevents the graphite material sticking to the flange surface. Therefore creating a gasket that can be easily removed, without damaging the flange surface finish.

These non-stick corrugated metal graphite gaskets are suitable for 150 lb and 300 lb flanges, where low bolt loads are common.
