3M 7100028820 Heat Shrink Thin-wall Tubing FP301 Clear

Product Description

The 3M 7100028820 is a clear, thin-wall heat shrink tubing from the FP-301 series, designed for insulation, bundling, and environmental protection of wire and cable assemblies. With a nominal diameter of 1/2 inch and a cut length of 6 inches, this tubing delivers a reliable 2:1 shrink ratio that conforms tightly to conductors and connector bodies when heat is applied. It provides a balanced combination of electrical insulation, physical protection, and chemical resistance suited to demanding industrial and military-grade wiring applications. Licensed electricians, panel builders, and MRO technicians use this product as a standard part of wire harness fabrication and repair.

FP-301 thin-wall tubing is well suited to residential and commercial electrical work, industrial control panels, and military or aerospace wiring assemblies. The clear jacket allows visual inspection of the underlying conductor or label after installation, which is useful in color-coded or labeled harness builds. The 6-inch length is practical for terminations, splices, and connector backshells where a short, precise section of protection is needed.

Key Features

• Clear tubing allows visual inspection of conductors and labels after shrinking
• Thin-wall construction provides a low-profile fit on wire and cable terminations
• Balanced electrical, physical, and chemical resistance properties for industrial and military applications
• 6-inch cut length suits splice and termination protection without excess waste
• 1/2-inch nominal diameter accommodates a range of wire gauges and connector bodies

Compatibility

Designed as an OEM-style heat shrink solution for general-purpose wire and cable insulation in industrial, commercial, and military wiring applications.

Installation Notes

Installation is performed by electricians, harness builders, or qualified MRO technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink over any conductor or termination. Use a calibrated heat gun rather than an open flame to apply even heat and achieve a uniform shrink without damaging the tubing or underlying insulation. Ensure the selected tubing diameter fits loosely over the conductor before shrinking to achieve a proper recovered fit.
