ALL-PURPOSE, SELF-FORMING GORE-TEX® VALVE STEM PACKING

GORE-TEX valve stem packing represents a significant improvement over other PTFE packings. The result of a remarkable new peocess, GORE-TEX valve stem packing offers a high degree of pliability. This allows GORE-TEX valve stem packing to conform to worn valve stems and stuffing boxes, eliminates the need for expensive repairs to older valves.

Soft, flexible GORE-TEX valve stem packing is easy to install. In most cases, itis not necessary to remove the valve from service, and no disassembly is required. When GORE-TEX valve stem packing is wound around a valve stem, pushed into the stuffing box and compressed by tightening the gland nut, it is compacted into a hogh-density packing. The result is a perfect, high-precision fit and a packing that fills flaws and irregularities - including those caused by wear. Once installed, a slight turn on the gland nut is all the maintenance that is usally required.

In typical applications on steam lines, GORE-TEX valve stem packing has consistently outperformed other packings. Time after time, GORE-TEX valve stem packing has sealed leaks permanently, where other packings had failed in days or weeks. And many of these applications are on worn valves; valves that have been in service for many years with frequent repackings.

Seals made with GORE-TEX valve stem packing last longer because the unique fibril structure of the material provides better strength, moldability, and conformability. GORE-TEX valve stem packing flows into imperfections in both the stem and stuffing box. The softness and self-lubricating nature of GORE-TEX valve stem packing practically eliminates stem wear.

GORE-TEX valve stem packing will not deteriorate with age, has a low coefficient of friction and withstands temperatures from -450°F to +550°F. In addition, GORE-TEX valve stem packing is unaffected by all common chemicals and will not contaminate product flow. It is the ideal packing for use in process lines in food and beverage operations, in chemical processing plants, and in petroleum refineries.

With only five sizes of GORE-TEX valve stem packing needed to pack most valves, substantial reductions in inventory are possible.

Added to this is the fact that GORE-TEX valve stem packing can be used in a wide range of applications, further reducing inventory by eliminating the need for many different kinds of packing.

GORE-TEX valve stem packing has an unequalled record of proven performance.

In chemical service, too, GORE-TEX valve stem packing has solved difficult problems sealing leaks which were costly and, in many cases, dangerous. Pharmaceutical plants, whiskey distilleries, and food processing plants have all found GORE-TEX valve stem packing a permanent solution to what once was a recurring problem - costly valve leaks.
