STYLE 2018
Braided Packing
Synthetic Yarn with PTFE, Dry
CONSTRUCTION
Style 2018 is an interlock braid using carded synthetic yarns thoroughly impregnated with PTFE suspensoid. The finished packing is again coated with PTFE dispersion.
APPLICATION / SERVICE
Style 2007 is chemically inert over the entire 0-14 pH range with these exceptions: molten alkali metals, flourides, aleum, fuming nitric acid, aqua regia, and other strong oxidizing agents
Style 2018 is a good general service packing with no lubricant. It can handle a broad range of chemicals in the 3-11 pH range, and is white in color so it will not discolor flow media. This style is typically used in valves and slow speed pumps where contamination from break-in lubricants cannot be tolerated.
