High-temperature Graphite Braided Packings

John Crane styles 1625G 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.
