Pilotpack 3410


High-performance packing manufactured from a specially lubricated yarn consisting of pure fine PTFE fibres. This additional lubricant helps the running-in process, allows operation under difficult conditions and maintains pliability for a longer period in service.

PILOTPACK 3410 packing also gives long life on solvents and chemicals used in the chemical, refining, food and beverage industries on valves, pumps and static applications such as tank lids.


  • Suitable for all chemicals especially solvents with the exception of molten alkali metals and fluorine
  • Suitable for pump, valve & static applications especially in the chemical industry
  • Operates over a wide range of parameters
  • Contains specially formulated lubricant for operation under difficult conditions

Chemical Compatibilities

  • For the pH range 0-14, the packing is chemically inert. Suitable for almost all chemicals except molten alkali metals and fluorine.

Sizes Available

  • All square sections from 3mm (1/8”) to 25mm (1”) are generally available from stock and supplied in differing lengths depending on the cross-section. Larger and rectangular sections can be manufactured to order. Packing can also be supplied in preformed or die formed rings.
