3M™ Heat Shrink Tubing EPS-400 is a dual wall tubing provides the advantage of integral, adhesive lined construction. This flame retardant tubing with a 4:1 shrink ratio offers insulation for 600V rated applications. The semi rigid polyolefin construction has an internal layer of thermoplastic adhesive which offers moisture seal protection in automotive and marine applications.3M™ Heat Shrink Tubing EPS-400 is color coded for quick and easy identification of the wire. It provides a skintight fit and strain relief protection for electronic components, truck wire splices, wire bundles and harness breakouts. This flame retardant tubing has a heat shrinkable outer wall that is cross linked for abrasion resistance. The inner adhesive helps to maintain high flow and good adhesion characteristics. When the tubing cools down, it forms a permanent, water resistant barrier. It withstands temperatures of 67 to 230 degrees F ( 55 to 110 degrees C). UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
