VK4

Vulcan VK4 is manufactured from KEVLAR® Aramid fibres. In order to get maximum benefit from this material, VK4 is specially treated with a high concentration of resilient, food quality lubricants and heavy PTFE dispersion. The resulting packing significantly reduces the shaft wear problems which have sometimes been associated with other KEVLAR® packing and, with this increased lubrication, higher shaft speeds of up to 4000 fpm (20m/s) can be handled.

VK4, KEVLAR® Aramid fibre lube packing, is a durable, economic general service packing for 80% of plant needs. The strength of fibre and construction of Vulcan VK4 leads to long packing life with extended periods between necessary gland adjustments.

Type VK4 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.
