MI-3902 is a multipurpose duplex braided packing braided from a unique Expanded Pure PTFE Fiber yarn which is incorporated with an advanced synthetic lubricant during its manufacturing. The expanded base yarn provides strength and dimensional conformability, thus ensuring easy installation and removal of the packing with excellent pliability. The break-in lubricant, further, lowers the coefficient of friction of the packing and helps the packing to dissipate the excessive heat generated during long time-run of the equipments. the lubricant also ensures cooler shaft runs without wear; hence, reducing the maintenance cost and also fills up the leak paths in the packing. The packing is resistant to most of the industrial chemicals and is non-contaminating in nature.
