Type VK4B

Kevlar® Aramid Packing

Vulcan VK4B is an interlace, square braid packing manufactured from KEVLAR® Aramid fibres impregnated with PTFE dispersion and specially treated with high-temperature break-in-lubricant. KEVLAR® offers a unique combination of extremely high tensile strength, lasting resilience, low thermal expansion, low coefficient of friction and wide chemical resistance.

Vulcan VK4B KEVLAR® gold fibre packing is a true multi-service packing that is well suited to the needs of many industries, particularly where physical strength in a packing is required. The strength of KEVLAR® is ideal for use as anti-extrusion, abrasion resistant, back-up rings, with other packing types, to increase the life of any packing combination.

Type VK4B standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

Applications: For pumps (rotary and reciprocating) and valves, including high pressure or high mechanical loading conditions, against abrasive slurries, sewage, effluents, water, oils, solvents and most chemicals. The non-staining superior lubrication of Vulcan VK4B means less wear and a higher shaft speed capability than some other KEVLAR® packing types. Suitable for use in the paper industry.
