Chesterton DualPac™ 2211 is built to address these issues by combining two complimentary materials in one packing. Using our patented braiding technology graphite filled ePTFE can be placed against the shaft where it provides superior sealing and low friction, and a high strength and resiliency aramid is placed against the stuffing box bore to resist consolidation without shaft wear.
