DualPac™ 2211

Severe Slurry Packing

By inventing a new braiding process, Chesterton has successfully combined ePTFE and aramid fibres in a unique configuration, allowing low-friction fibres to seal the shaft and resilient fibres to provide strength and anti-extrusion benefits. Combined in this way DualPac 2211 provides all of the performance advantages of ePTFE and aramid without the compromises of traditional mixed fibre packing.
