3M™ FP-301 Heat Shrink Tubing is a general-purpose, thin-wall tubing that provides a balance of electrical, physical and chemical properties, making it perfect for industrial and military applications. This tubing has a 2:1 shrink ratio and provides flame-retardant insulation for 600V-rated applications. It has a flexible polyolefin construction that offers moisture-seal protection.

3M™ Heat Shrink Tubing FP-301 is color-coded for quick and easy identification of the wire. This split-resistant, flame-retardant tubing is used as shrink-fit, electrical insulation over cable splices or terminations. The high-expansion-ratio tubing is mechanically tough, easily markable and resists cold flow. It is perfect for lightweight wire-harness covering, fire-resistant covering, wire marking, wire bundling and component packaging. It withstands temperatures of -67 to 275 degrees F (-55 to 135 degrees C). UL Listed, SAE-AMS-DTL-23053/5, Class 1, 2, AMS-3636, AMS-3637, CSA Certified and RoHS 2011/65/EU Compliant.
