Datasheet 1585


This unique packing effectively handles water, steam, boiler feed and aqueous solutions of acids and alkalis. The excellent thermal conductivity allows the packing to dissipate heat from the shaft, protecting the pump while operating at lower drip rates. Style 1585’s thermal expansion rate is close to that of surrounding metal parts. It seats quickly, breaks-in without extensive adjustments and will not grow as TFE does.

Typical Applications

  • High-speed pumps, blowers and driers
  • High-temperature valves
  • Furnace gasketing
  • Use as anti-extrusion rings with 4010AF for extended life in boiler feed, condensate pumps and turbines
