The 3M 7010400861 is a thin-wall heat shrink tubing segment from the FP-301 product line, measuring 3/16 inch in diameter and 48 inches in length in green. This tubing is designed to provide reliable insulation, strain relief, and environmental protection for wire bundles, terminals, and splices. It delivers a balanced combination of electrical insulation, physical durability, and chemical resistance. Licensed electricians, panel builders, and field technicians working in industrial and military-grade wiring applications install this tubing using a heat gun to achieve a clean, secure sleeve over conductors and connections.
This heat shrink tubing is suited for industrial wiring harnesses, control panel builds, military and aerospace wiring assemblies, and general electrical insulation tasks. The green color aids in circuit identification and color-coding of wire runs. Its thin-wall construction keeps finished bundle diameters compact, making it practical in space-constrained enclosures and junction boxes where bulkier wall profiles are not acceptable.
Designed as an OEM-style heat shrink sleeve for use on standard wire and cable insulation tasks in industrial and military electrical assemblies where FP-301 thin-wall tubing is specified.
Installation is performed by licensed electricians or qualified wiring technicians. De-energize and lock out all circuits before applying heat shrink tubing to any live wiring assembly. Use a calibrated heat gun set to the appropriate shrink temperature for FP-301 material, working from the center outward to prevent air pockets. Avoid open-flame heat sources, as they can cause uneven shrink or damage the tubing wall.
