Product Information

RB16 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. RB16 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, RB16 is square interbraided via a CROSS-LOK® process. The construction of RB16 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 RB16s CROSS-LOK® braided helps overcome extrusion problems, which can be the one negative of this fibre, particularly in lower quality braids.

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% ofthe true utilisation cost, Robust Msa 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.

Product Information

RB17 packing is manufactured from 100% 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. G1 yarn is constructed from PTFE tape and Graphite inter-locked to create a true synergy between these two premier packing materials. High temperature break-in and running lubricants are added to the yarns, prior to braiding in our CROSS-LOK® lattice. The result is an exceptional process packing that gives, often many times, longer service life in the vast majority of applications. With the exceptions of high mechanical load (highly abrasive media or high pressure) or temperatures above PTFE’s limit of 280°C, RB17 is ultimate packing. RB17 resists all chemicals across the entire Ph range (except Oleum, Aqua Regia, fuming Nitric Acid and Fluorine), is self lubricating and does not shrink, harden nor dry out. The packing is very cool running with exceptionally good thermal conductivity thus practically eliminating shaft scoring.

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, Robust Msa 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.
