3M 7000133691 Heat Shrink Thin-wall Tubing 1 in 6 in Black

Product Description

The 3M 7000133691 is a thin-wall heat shrink tubing from the FP301 series, designed to provide reliable electrical insulation, physical protection, and chemical resistance across a wide range of industrial and military wiring applications. Cut to a 6-inch length and sized at 1 inch in diameter, this black tubing delivers a clean, low-profile sleeve over wire terminations, splices, and connector backshells. Licensed electricians, military contractors, and industrial maintenance technicians rely on FP301-series tubing where a consistent shrink ratio and durable wall are required without the bulk of adhesive-lined products.

This tubing is suited for applications where wiring bundles, terminals, or bare conductors need insulation and abrasion protection in both commercial and industrial environments. The black color aids in visual identification and UV resistance in exposed installations. At 6 inches per piece and sold in packs, it is practical for bench termination work, field repair kits, and production line assembly where consistent sleeve lengths are needed.

Key Features

• Thin-wall construction provides low-profile insulation without adding excessive bulk to wire assemblies
• FP301 series formulation balances electrical, physical, and chemical resistance properties
• Black color supports visual organization and offers UV resistance in exposed installations
• Pre-cut 6-inch length simplifies bench and field termination work
• 1-inch nominal diameter accommodates a range of wire and connector sizes

Compatibility

Designed as an OEM-style heat shrink sleeve for industrial, commercial, and military wiring applications requiring thin-wall tubing in the 1-inch diameter range.

Installation Notes

Heat shrink tubing of this type is typically installed by electricians or electronics technicians using a heat gun set to an appropriate low-to-medium temperature range. De-energize and lock out all circuits before sleeving any live conductors or terminals. Slide the tubing over the conductor or splice before making the final termination when possible, then apply heat evenly along the length to achieve a uniform shrink. Avoid open-flame heat sources, which can scorch or unevenly shrink the tubing.
