The Pikotek® VCS® gasket provides exceptional insulating and general sealing performance in aggressive material applications. The VCS gasket is suitable in all services up to and including ANSI 2500# and API 10,000# classes.¹
Due to its unique pressure activated sealing mechanism, the gasket requires far less bolt stress to seal than any other gasket.² The VCS gasket inner diameter is exactly matched to the flange bore to eliminate turbulent flow and flange face erosion/corrosion. The seal elements are replaceable in the reusable gasket retainer.
