Graphite Metal Reinforced Sheets
Graphite Metal Reinforced Sheets
These sheets are calendared with metal reinforcements to improve handling and blow out resistance. The reinforcements enable high pressure performance and troble free service. The gaskets are suited for all types of flange designs and in many cases replace spiral wound gaskets. Cut Gaskets are available as per various flange standards and custom sizes or drawings.
