Flax packing built to withstand high heat and reduce friction.PTFE Flax Shaft Packing is braided from flax rovings and is then impregnated with PTFE lubricant. The combination ofthe quality flax and the PTFE lubricant provides a packing that has a higher performance level thanconventional packings. Packaged in 2' lengths.Key FeaturesProtects propeller shafts and prevents the bilge from filling with waterDissipates heat away from the stuffing boxPTFE flax packing is braided from flax rovingThermal conductive material allows the propeller shaft to run cooler and efficientlyWill not scar, bind, freeze or contribute to misalignment of shaftResistant to frictional heatBraided from quality flax roving
