VF4 is braided from selected, long fibre, heavy duty, flax yarns thoroughly impregnated yarn by yarn with PTFE and treated with break-in lubricants. The packing is designed to give a very low coefficient of friction, resistance to wear and rotting, good compressibility, high flexibility, high tensile strength and comparative ease of installation and take-up, especially on large cross-sections.

Vulcan VF4 PTFE Flax packing is specially designed to seal large cross-sectional areas and is ideal to solve the exacting sealing requirements of stern glands in the marine field. The packing will also be of superior service in heavy reciprocating machinery, rotary applications handling abrasive media and heavy-duty static applications such as tank lid seals.

Type VF4 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

Applications: For use in the paper, marine, chemical, pharmaceutical, sugar and water industries against salt water, slurries, hydrocarbons, oils, greases and solvents.
