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 Packings produced using smaller or outdated braiding machines lack the strength of true cross-lock, are less dense and are not as square in cross-section.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 VT9L
Product Information
Vulcan Type VT9L is braided from pure PTFE fibres, in the form of muti-filament yarns, vacuum impregnated with PTFE dispersion and saturated with chemically resistant lubricants.
Applications
The enhanced lubrication and multi-filament yarn treatment of Vulcan VT9L allows greatly extended service capability in pumps up to 12m/s surface shaft speed. For use against solvents and virtually all chemicals with the exceptions of molten and alkali metals and fluorine.

Type VO2
Product Information
Vulcan Type VO2 is a braided flange gasketing tape made from strong, resilient PTFE yarns thoroughly impregnated with PTFE dispersion and inert lubricants.
Applications
Vulcan Type VO2 forms an endless seal for any diameter flange on chemical reactor vessels, tank covers, ducts, etc. Vacuum can be sealed up to 30ÓHg. The maximum pressure this product can handle is strongly determined by temperature and other factors. Care should be taken when first installed.

PTFE GRAPHITE PACKINGS
Type VP1
Product Information
Vulcan Type VP1 is 100% GORE GFO fibre packing. This remarkable yarn is constructed from PTFE and Graphite intimately blended and locked and then treated with a high temperature, break-in lubricant.
Applications
See as per Style VP1B.

Type VP1B
Product Information
Vulcan VP1B is 100% GORE GFO fibre without the inclusion of any additional lubricants.
Applications
The GORE GFO fibre solely used in Vulcan Types VP1 and VP1B creates a packing that will give longer service life, lower maintenance costs and less down time in a great variety of applications. The cool running, high speed, near universal chemical resistance of GFO, makes Vulcan Type VP1 suitable for use in any rotary, reciprocating or static gland, against all chemicals bar very strong oxidisers such as Oleum, Aqua Regia, fuming Nitric Acid and Fluorine.
The VP1B is specially for use in non-contaminating applications. With VP1B, shaft speed capability is lowered and packing break-in may need more care due to the lower lubrication.

Type VP2
Product Information
VP2 packing is manufactured from 100% Vulcan Type G1 fibre. This newly developed outstanding yarn is very similar in material construction to the original GORE GFO fibre and has been manufactured to optimise performance at an improved cost.
Applications
For use wherever the value of the best quality and material packing can be realised. Since the actual purchase cost of a packing is typically only 3% of the true utilisation cost, Vulcan recommend these PTFE GRAPHITE packings for all possible applications. They will increase service life whilst minimising wear and gland adjustments, against nearly all media in static, rotary and reciprocating uses.
