 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. 

 John Crane styles 1330, 1332, 1335 and C1061 are cost-effective general-service packings constructed of the highest-quality synthetic fibers and lubricants. These products are designed to handle a wide range of fluids at moderate to high temperatures, pressures and shaft speeds. These styles are thoroughly impregnated with PTFE to enhance chemical resistance, lubricity and dimensional stability. This helps to ensure even gland load distribution and to promote longer packing life 

 John Crane styles 1625G, 1626, 1635G and N1635 are the ultimate in packing, offering the ability to perform in both high temperatures and a full range of chemical services. These packings meet the demands of today’s high-performance requirements. Constructed of the highest quality, continuous filament graphite fibers, provide superior sealability and heat dissipation with minimal flush.

Highly lubricous, these densely braided products offer reduced process contamination and ease of start-up, installation and adjustments. These styles feature dimensional stability, which helps to ensure even gland load distribution and promote longer packing life.
