3M 7100086437 FP301 Heat Shrink Tubing 3/8 in 48 in Black

Product Description

The 3M 7100086437 is a length of FP301 thin-wall heat shrink tubing measuring 48 inches long with a 3/8-inch recovered diameter, supplied in black. FP301 tubing is a polyolefin-based product designed to provide reliable electrical insulation, strain relief, and environmental protection on wire bundles, cable ends, and splices. It is rated for use across a broad temperature range and shrinks uniformly when heat is applied with a heat gun or oven. Electricians and wire harness technicians use this tubing in industrial control panels, marine wiring, and military-specification assemblies where consistent performance under mechanical stress and exposure to fluids is required.

FP301 thin-wall heat shrink tubing is suited for both industrial and military applications where a balance of electrical, physical, and chemical resistance is needed. Typical uses include insulating and bundling conductors in control cabinets, protecting wire terminations in harsh environments, and adding strain relief at connector entries. The 48-inch length allows technicians to cut custom sections for varied wire gauges and bundle sizes on the job.

Key Features

• Thin-wall polyolefin construction provides flexibility after recovery
• 48-inch length supports custom cuts for multiple terminations from a single piece
• 3/8-inch nominal diameter fits a common range of wire gauges and small cable bundles
• Black color provides UV resistance and visual uniformity in finished assemblies
• Balanced electrical, physical, and chemical properties suitable for industrial and military use

Compatibility

Designed as an OEM-style heat shrink solution for wire insulation and protection applications across industrial control, marine, and military-grade electrical assemblies.

Installation Notes

Installation is performed by licensed electricians or qualified wire harness technicians. De-energize all circuits before applying heat shrink tubing to any wiring. Use a calibrated heat gun set to the manufacturer-recommended recovery temperature and move it evenly along the tubing length to achieve uniform shrinkage without scorching. Refer to applicable NEC guidelines for conductor insulation requirements when specifying tubing for panel or field wiring.
