PTFE Impregnated Lubricated Kevlar® Gland Packing (VK4)
PTFE Impregnated Lubricated Kevlar® Gland Packing (VK4)
- 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 VK4 leads to long packing life with extended periods between necessary gland adjustments.
