Gland Packings
All Vulcan packings are square-braided on the most advanced specification braiding machines available. Twenty four and thirty six track braiders are utilised to produce four-ply, square inter-braid packings on all sizes from 3/8" (10mm) upwards. Fibres are run from the core of the packing section to the corner-posts and surfaces, whilst being cross-locked in a square, lattice construction, to produce maximum resilience and a highly dense, square packing.
The quality of a packing's braiding significantly affects the service life of the packing. Packings produced using smaller or outdated braiding machines lack the strength of true cross-lock, are less dense and are not as square in cross-section. The looser the braid of a packing, the lower its durability will be. Additionally, greater gland pressure is required to perform a seal, resulting in increased mechanical stress. As the packing deteriorates, frequent gland adjustments are required, causing more mechanical stress on the packing, leading to accelerated failure.

Type VK4T
Product Information
Vulcan VK4T combines the physical strength of KEVLAR with the sealing properties of TEFLON fibres. The packing is further lubricated yarn by yarn with PTFE dispersion and inert lubricants.
Applications
Vulcan Type VK4T combines low-friction, complete pH range chemical resistance with high mechanical and dimensional strength. A wide ranging packing, for specification especially in high pressure conditions in chemical or abrasive applications, where alternative single fibre packings may extrude or cause significant shaft wear.
The construction and materials of VK4T makes this packing ideal for piston sealing on reciprocating, chemical, slurry and high pressure pumps.
