3M 7100020270 Heat Shrink Tubing FP-301 3/8 in Black 200 Ft

Product Description

The 3M 7100020270 is a thin-wall heat shrink tubing sold under the FP-301 product line. It provides a reliable combination of electrical insulation, physical protection, and chemical resistance suited to demanding industrial and military wiring applications. The tubing ships on a bulk 200-foot spool in a 3/8-inch diameter size and black color, making it practical for large runs of wire bundling, insulation repair, strain relief, and environmental sealing. Licensed electricians and wire harness technicians are the primary installers for this product type.

FP-301 thin-wall heat shrink tubing is well suited to residential, commercial, and industrial electrical work wherever a clean, durable insulating sleeve is required. Common applications include wire termination protection, connector strain relief, cable identification, and bundle organization. The black color is widely used for standard wiring and low-visibility routing. The bulk spool format is appropriate for production environments and high-volume service work where pre-cut lengths would be inefficient.

Key Features

• Thin-wall construction allows compact shrink profile without excessive wall buildup
• Balanced electrical, physical, and chemical properties for industrial and military use cases
• Black color suitable for standard wire insulation and low-visibility cable routing
• 3/8-inch diameter accommodates a range of wire gauges and small connectors
• 200-foot bulk spool format reduces waste and supports high-volume production runs

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeving for industrial and military wiring applications where FP-301 series tubing is specified.

Installation Notes

Heat shrink tubing of this type is installed by electricians and wire technicians using a heat gun set to the appropriate shrink temperature for the tubing material. Always de-energize circuits completely before applying any sleeving to conductors or terminations. Slide tubing over the conductor or connector before terminating where possible, as post-termination installation may require cutting. Follow applicable NEC requirements for insulation ratings and ampacity when selecting sleeving for specific conductor types.
