Vulcan Type VP1<br />
Product Information<br />
<br />
Vulcan Type VP1 is 100% GORE GFO fibre packing.<br />
<br />
This remarkable yarn is constructed from PTFE and Graphite intimately blended and locked and then<br />
treated with a high temperature, break-in lubricant.<br />
<br />
Vulcan VP1 is an outstanding packing for use in aggressive or arduous duties including the most<br />
difficult chemical environments.<br />
<br />
It is essentially chemically inert over the entire pH range.<br />
<br />
The unique combination of locked graphite and PTFE creates a yarn with very high thermal<br />
conductivity, that does not harden, shrink, swell nor dry out and that is exceptionally smooth that, in<br />
practically all cases, greatly extended service life can be expected.<br />
<br />
In order to obtain maximum benefit from this fibre, Vulcan VP1 is square interbraided via a<br />
CROSS-LOK process.<br />
<br />
The construction of VP1 increases the durability of the packing and reduces the gland pressure<br />
required to form a seal.<br />
<br />
Periods between gland maintenance and packing replacements are thus even further extended and<br />
Type VP1 CROSS-LOK braiding helps overcome extrusion problems, which can be the one negative<br />
of this fibre, particularly in lower quality braids.<br />

Product Information<br />
<br />
VP2 packing is manufactured from 100% Vulcan Type G1 fibre.<br />
<br />
This newly developed outstanding yarn is very similar in material construction to the original GORE<br />
GFO fibre and has been manufactured to optimise performance at an improved cost.<br />
<br />
G1 yarn is constructed from PTFE tape and graphite inter-locked to create a true synergy between<br />
these two premier packing materials.<br />
<br />
High temperature break-in and running lubricants are added to the yarns, prior to braiding in our<br />
CROSS-LOK lattice.<br />
<br />
The result is an exceptional process packing that gives, often many times, longer service life in the<br />
vast majority of applications.<br />
<br />
With the exceptions, if high mechanical load (highly abrasive media or high pressure) or<br />
temperatures above PTFE’s limit of 280ºc, Vulcan VP2 is the ultimate packing.<br />
<br />
Vulcan VP2 resists all chemicals across the entire Ph range (except Oleum, Aqua, Regia, fuming<br />
Nitric Acid and Fluorine), is self lubricating and does not shrink, harden nor dry out.<br />
<br />
The packing is very cool running with exceptionally good thermal conductivity thus practically<br />
eliminating shaft scoring.<br />
Applications<br />
<br />
For use whenever the value of the best quality and material packing can be realised.<br />
<br />
Since the actual purchase cost of a packing is typically only 3% of the true utilisation cost, Vulcan<br />
recommend these PTFE GRAPHITE packings for all possible applications.<br />
<br />
They will increase service life whilst minimising wear and gland adjustments, against nearly all<br />
media in static, rotary and reciprocating uses.<br />
