Pilotpack 3408

Product Type: Pilot® Gland & Valve Compression Packings

Product Features

Designed for use on oxygen applications

Suitable for pump, valve and static applications especially in the chemical industry
Operates over a wide range of parameters
Manufactured from a pure PTFE yarn that contains no impregnation

Description

Pilotpack 3408 has a high-performance packing manufactured from a yarn consisting of pure fine PTFE fibres containing no impregnation or additives.

The yarn also has a very low coefficient of friction that allows relative movement between the fibres. When this yarn is braided using the ‘Crossplait’ technique of manufacture, this gives the packing a ‘self-lubricating’ property that increases service life.

PILOTPACK 3408 packing has been specially developed for use on oxygen applications (which require a very pure product with no lubricants as these can react with oxygen) It can also give 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.
