​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Unique to Chesterton, 1727 Multi-Lon® is a synthetic packing designed specifically for general service pump applications. It is able to deliver performance equal to synthetics with the pliability of asbestos. Unlike the first generation of synthetic packing, Mul​ti-Lon does not suffer from limitations that prevent general service use. Multi-Lon consists of inter​-braided, continuous, synthetic thermoset fibers immunized with PTFE lubricant and a special silicone-free, break-in, sacrificial lubricant.
Unlike many synthetic yarns, it does not cause severe scoring
Does not cause electrolytic pitting like carbon or graphite yarns
Does not have the shaft speed limitations or the elongation/ extrusion problems often associated with PTFE fiber yarns
