3M 7000133640 FP301 Heat Shrink Tubing 1/8 in Clear 25pc

Product Description

The 3M 7000133640 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable insulation and mechanical protection for wire splices, terminals, and conductor bundles. Each piece measures 1/8 inch in recovered diameter and 48 inches in length, with a clear jacket that allows visual inspection of the connection beneath after shrinking. The FP-301 formulation delivers a balanced combination of electrical insulation, physical durability, and resistance to common industrial chemicals, making it a dependable choice for both industrial wiring and military-specification applications. This package contains 25 pieces.

FP-301 thin-wall heat shrink tubing is used across a broad range of applications including electrical panel wiring, harness fabrication, terminal insulation, and connector protection. The 1/8 inch size is well suited for small-gauge conductors and low-voltage signal wiring. Electricians, avionics technicians, panel builders, and MRO professionals typically reach for this tubing when a clean, low-profile sleeve is needed without the bulk of adhesive-lined or thick-wall alternatives.

Key Features

• Thin-wall construction provides a low-profile finished sleeve without added bulk
• Clear jacket allows visual verification of the underlying connection or conductor after shrinking
• 1/8 inch nominal diameter suits small-gauge wire and low-voltage signal conductors
• 48-inch piece length allows cutting to custom lengths on the job
• Balanced electrical, physical, and chemical resistance properties for industrial and military applications
• Pack of 25 pieces sold as a single unit (UOM: Each)

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve suitable for insulating wire splices, terminals, and conductor bundles in industrial, commercial, and military wiring applications where a 1/8 inch recovered diameter is required.

Installation Notes

Heat shrink tubing of this type is installed by electricians and wiring technicians using a heat gun or similar controlled heat source. Always de-energize circuits completely before applying sleeving over any conductor or termination. Apply even heat along the length of the tubing to achieve a uniform, wrinkle-free shrink. Avoid open flames, as uneven heat can damage the tubing and the underlying conductor insulation.
