The carbon-graphite based packings are all designated for a resistance to superior temperatures. Their resistance to chemical products is also comparable to those of the PTFE® packings. Many combinations with other fibers are also available to fulfill many applications, including high temperature valves.
The 3R 746 packing is manufactured from high purity flexible graphite that is expanded and formed into a braidable yarn and then braided without binders or wire reinforcement. Learn more >
