Flexible Graphite Gasket

Crane-Foil® is a premium-grade flexible graphite gasket material used in a wide range of services, where conventional gaskets will not withstand extreme temperature and/or pressures. Crane-foil gaskets feature the benefits of graphite, including resistance to most fluids, high temperatures and pressure changes. They provide excellent sealing, preventing product leakage and minimizing change-outs. Resistance to cold flow, weathering and aging make Crane-foil ideal where increased reliability is necessary.
