Product Description
VK5.7/8 7/8inch Kevlar & Gore (R) Fibre Gland Packing x 8m

Vulcan Types VK5 and VK4T combine the benefits of the remarkable properties of two outstanding Gland Packing fibres, G1 has the best combination of features of any packing fibre but it may extrude or deteriorate in high mechanical loading conditions. The addition of DuPont’s KEVLAR® adds steel-like strength. VK5 G1 KEVLAR® combi-packing is square inter-braided to add the strength of KEVLAR® where it is most needed on the corner posts for dimensional stability and to resist extrusion. The G1 yarns are braided to the packing surfaces to enhance smooth running and sealing capability.

VK4T follows the same principles and benefits but utilises PTFE fibres rather than G1. Vulcan VK5 is the packing for extended life in high pressure or mechanical load conditions, particularly on worn or large tolerance equipment and in the most demanding chemical environments. Shaft wear is virtually eliminated, and high speeds and aggressive chemicals can be handled, because of the presence of G1 on sealing faces. Extrusion and gland maintenance is negligible, even in the most arduous of applications, due to the inter-locked braiding of KEVLAR®. Type VK5 standard spool length is 8 metres.

Applications : Types VK5 and VK4T combine mechanical strength with surface lubricity to give a long-lasting, high-performance sealing, near universal packing, for use in all rotary, reciprocating and static gland applications.
