3M 7100020271 FP-301 Heat Shrink Tubing 3/8 in Red 200 Ft

Product Description

The 3M 7100020271 is a thin-wall polyolefin heat shrink tubing sold in a 200-foot bulk spool. Designated as FP-301, this tubing delivers a reliable balance of electrical insulation, physical protection, and chemical resistance suited to demanding industrial and military wiring applications. The 3/8-inch nominal diameter accommodates a range of wire bundles and terminations. When heat is applied, the tubing shrinks uniformly to form a tight, protective sleeve over conductors, splices, and connector backshells. Licensed electricians, military depot technicians, and industrial maintenance professionals are the primary installers.

FP-301 thin-wall heat shrink tubing is used across a broad range of applications including wire harnessing, cable bundling, terminal insulation, and strain relief in both industrial facilities and military equipment. The bulk 200-foot spool format is practical for production environments, panel shops, and service fleets that require frequent cuts to custom lengths. The red color aids in circuit identification and color-coded wiring schemes.

Key Features

• Thin-wall FP-301 polyolefin construction balances flexibility with electrical insulation performance
• 3/8-inch nominal diameter suits mid-range wire gauges and small connector bodies
• Red color supports color-coded wire and cable identification
• 200-foot bulk spool minimizes handling and allows on-demand cutting to length
• Rated for industrial and military wiring applications requiring chemical and abrasion resistance

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve compatible with standard wire, cable bundles, splices, and connector backshells requiring a 3/8-inch nominal shrink tubing in industrial and military wiring installations.

Installation Notes

Heat shrink tubing of this type is installed by electricians and wiring harness technicians using a heat gun or convection oven set to the appropriate activation temperature. Always de-energize circuits completely before sleeving any conductor, splice, or terminal. Cut tubing to the required length before applying heat, and apply heat evenly along the length of the tubing to achieve uniform shrinkage. Refer to applicable NEC or military wiring specifications for minimum insulation and sleeving requirements on the installation.
