3M 7010400858 Heat Shrink Thin-wall Tubing 2 in Red FP301

Product Description

The 3M 7010400858 is a thin-wall heat shrink tubing in the FP-301 series, supplied in a 48-inch length with a 2-inch nominal diameter in red. It is designed to provide reliable electrical insulation, mechanical protection, and environmental sealing for wire bundles, splices, terminals, and cable assemblies. FP-301 thin-wall tubing applies a controlled shrink when exposed to heat, conforming tightly to the underlying substrate. Electricians, industrial maintenance technicians, and military-specification wiring crews install this tubing across a wide range of applications where consistent dielectric protection and physical abrasion resistance are required.

This tubing is suited for both industrial and military wiring applications where a reliable, low-profile insulating sleeve is needed. Common use cases include insulating wire splices, covering terminal connections, bundling multi-conductor runs, and providing strain relief on cable exits. The red color coding aids in circuit or phase identification during installation and inspection. This SKU ships as a pack of 24 pieces, each 48 inches in length, making it practical for bench-stock use in panel shops, field service kits, and production wiring environments.

Key Features

• Thin-wall FP-301 construction delivers electrical insulation with minimal added bulk
• 2-inch nominal diameter accommodates larger wire bundles and cable assemblies
• 48-inch piece length allows field cutting to required dimensions
• Red color supports visual identification and color-coded wiring practices
• Balanced electrical, physical, and chemical resistance properties for industrial and military use
• Pack of 24 pieces supports bench-stock and production quantity needs

Compatibility

Designed as an OEM-style thin-wall heat shrink sleeve suitable for general industrial and military wiring harness, splice insulation, and terminal protection applications where FP-301 series tubing is specified.

Installation Notes

Installation is typically performed by licensed electricians or trained wiring technicians. De-energize all circuits completely before applying heat shrink tubing to any live wiring assembly. A heat gun set to the appropriate shrink temperature should be used and moved evenly along the tubing length to achieve uniform shrinkage without scorching. Follow applicable NEC guidelines and any project-specific military or industrial wiring standards when selecting tubing diameter and wall thickness for the application.
