Graphite and PTFE Impregnated Lubricated Gland Packing (VP1)
Graphite and PTFE Impregnated Lubricated Gland Packing (VP1)
- VP1 is 100% GORE® 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.
- VP1 is an outstanding packing for use in aggressive or arduous duties including the most difficult chemical environments.
- It is essentially chemically inert over the entire pH range.
- The unique combination of locked Graphite and PTFE creates a yarn with very high thermal conductivity, that does not harden, shrink, swell nor dry out and that is exceptionally smooth running with negligible shaft wear.
- User experience with G1 fibre has shown that, in practically all cases, greatly extended service life can be expected.
- In order to obtain maximum benefit from this fibre, VP1 is square inter-braided via a CROSS-LOCK® process.
- The construction of VP1 increases the durability of the packing and reduces the gland pressure required to perform a seal.
- Periods between gland maintenance and packing replacement are thus even further extended and Type VP1‘s CROSS-LOCK® braiding helps overcome extrusion problems, which can be the one negative of this fibre, particularly in lower quality braids.
