Chesterton Flange Sealing program offers a complete range of gasket materials that provide excellent sealability and
superior reliability. Our line of sheet, tape, semi-metallic and metallic gaskets covers a broad range of applications from critical high performance and specialty flange sealing products to general service
products suitable for plant wide use.
Critical Flange Sealing
ECS Environmental Containment Sheet – LINK
Our ECS sheet provides the full range of structured PTFE materials and service requirements suitable for FDA, chemically aggressive, high pressure and temperature services up to 500˚F (260˚C). ECS is an excellent choice for Chemical and Hydrocarbon plants. ECS gaskets are recommended for service in water, steam, hydrocarbons, solvents, refrigerants, caustics and strong acids.
459 Graphite Sheet – LINK
459 is a graphite sheet with nickel foil reinforcement designed for use in high pressure, high temperature flange applications. It has excellent chemical resistance and can be used to 850˚F (450˚C) in an oxidizing service and to 1600˚F (870˚C) in a non-oxidizing service.
Steel Trap® – LINK
Steel Trap is the preferred gasket when needing improved performance at a minimum seating stress. It features fire, blow out and leak proof benefits along with the sealing properties of an encapsulated element in a compression seal. Steel Trap is the ideal replacement for problem applications. Steel Trap is available in standard and custom designs, including the unique self-locating design.
Flange Live Loading System – LINK
Chesterton Flange Live Loading increases flange reliability by increasing the elastic energy in the flange assembly. This ensures that a pre-calculated gasket stress is maintained at all times, regardless of pressure fluctuations, gasket thickness loss, or thermal cycles. Chesterton flange discs are specially designed for flange applications and maintain their flexibility under extreme mechanical and thermal conditions.
