3M 7000133687 Heat Shrink Thin-wall Tubing 1/2 Inch Black

Product Description

The 3M 7000133687 is a thin-wall heat shrink tubing in the FP-301 series, designed to provide reliable insulation, strain relief, and environmental protection for wiring and cable terminations. Cut to a 6-inch length with a 1/2-inch diameter, this tubing is suited for a broad range of industrial and military-grade electrical applications. The FP-301 formulation delivers a balanced combination of electrical insulation, physical durability, and chemical resistance, making it a dependable choice for licensed electricians and wire harness technicians working in demanding environments.

This tubing is applied to wire splices, terminal connections, and bundle breakouts in both fixed and mobile electrical installations. It is commonly used in control panel wiring, field wiring repairs, and military or aerospace-adjacent applications where consistent shrink performance and insulation integrity are required. The black color suits applications where UV exposure or a neutral finish is preferred.

Key Features

• Thin-wall construction allows fast, even shrink with standard heat sources
• 6-inch pre-cut length for quick application without field cutting
• 1/2-inch diameter accommodates a range of conductor and bundle sizes
• Balanced electrical, physical, and chemical resistance properties per FP-301 series specification
• Black finish suitable for UV-exposed or color-coded wiring schemes
• Sold in packs with a minimum order quantity of 10 units

Compatibility

Designed as an OEM-style heat shrink solution for industrial and military electrical wiring applications requiring a 1/2-inch thin-wall tubing with standard shrink ratio performance.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any conductor or terminal. Use a calibrated heat gun rather than an open flame to achieve uniform shrink and avoid damage to adjacent components or insulation. Ensure the tubing fully covers the intended splice or termination before applying heat.
