FIRST ON THE MARKET!
Robco was the original braider to introduce GFO® compression packing to the market :
We actually participated in the development of the material and subsequent field testing. Robco knows GFO®!
1140GFO® possesses the most efficient set of physical characteristics to remain, to this day, the #1 choice as universal mill compression packing. We produce it from high tensile modulus PTFE (polytetrafluoroethylene) yarn into which a high percentage of micronized graphite and a small percentage of dimethylsiloxane (silicone lubricant) is added. GFO® fibre’s combination results in a packing that retains nearly all of pure PTFE’s chemical resistance while operating at high pump speeds in cool liquids.
