Gasket and Flange Sealing

Chesterton provides a robust selection of flange and gasket sealing products engineered for reliable performance under high temperature, high pressure, and harsh industrial conditions. Their offerings include semi-metallic and spiral-wound gaskets featuring metal cores with graphite or PTFE fillers for superior recovery and leak prevention. They also offer advanced manway and access-cover gaskets, such as Steel‑Trap metal-core variants, ensuring durable sealing even with thermal cycling and pressure fluctuations.

To further enhance flange integrity and reduce maintenance, Chesterton supplies specialized live-loading components—disc springs and bolt spacers—that maintain constant flange pressure over time. These solutions improve long-term leak prevention and simplify maintenance, making them ideal for critical applications in petrochemical, power, refining, and other heavy industries.
