Flexidram™ Kammprofile


The Flexitallic Flexidram™ is a hybrid fire-safe gasket comprising a machined outer Flexpro™ (Kammprofile) ring faced with graphite with a specially cleaned Sigma® 501 internal ring.

The Flexidram™ gasket has been designed for use in applications in the food and beverage industries where there is a requirement for a clean, non contaminating fire-safe seal. E.g. the distillation of fermented alcohol containing fluids, in the manufacture of flammable high spirit liquors such as whisky, brandy etc.

It is the only Food and Drug Administration (FDA) compliant fire-safe gasket capable of sealing effectively, using the low bolt stress available with stainless steel flanges.
