Shrink Tubing for Every Application 3M? Heat Shrink Tubing Series FP-301 and Cold Shrink Connector Insulators Series 8420 offer an outstanding balance of electrical, physical, and chemical properties for a wide variety of industrial and military applications. 3M? Heat Shrink Tubing FP-301 Series is split resistant, mechanically tough, easily marked, and resists cold flow. FP-301 tubing is rated for continuous operation at -67°F to 275°F, and is designed to withstand elevated temperatures to 572°F for short periods.
3M? Cold Shrink Series 8420 are open-ended, tubular, rubber sleeves which are factory expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation over an inline connection and terminal lug, allowing the tube to shrink and form a water-resistant seal.
