VCS Very Critical Service Flange Insulation Gasket kit is a high reliability gasket used for both isolating and general sealing purposes in Very Critical Services. The gasket has a proven track record of integrity in aggressive sealing situations. The VCS is suitable in all services up to and including ANSI 2500# and API 10,000# classes. The VCS is designed for service where the cost of gasket failure cannot be tolerated. The VCS gasket consists of a PTFE (Teflon) spring-energized face seal, or an elastomeric o-ring, seated in an isolating laminate, which is permanently bonded to a high-strength stainless steel 316 metal gasket core.
Due to its unique pressure activated sealing mechanism, the gasket requires far less bolt stress to seal than any other gasket. 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.

The core of each gasket is made of annealed ss 316 stainless steel. Other metals, including Duplex and Inconel are available upon special order.
