Style 919
Material composition: Braided from graphited PTFE (gPTFE ) yarn. The packing is soft. There are no free particles of graphite on surface and therefore no contamination can
Application: Used in pumps, valves, mixers and agitators. Especially designed for services
involving surface speeds and temperature higher than those normally speified for pure PTFE packings . Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents.
Benefits: Because of its extremely wide applciation range, successfully replace many other packings and reduce stock levels considerably.
