3M 7000133583 Adhesive-lined Heat Shrink Tubing 48 in

Product Description

The 3M 7000133583 is a dual-wall, adhesive-lined heat shrink tubing rated under the EPS300 series, designed to provide environmental protection and electrical insulation for wire splices, wire bundles, and harness breakouts. The outer wall is made from flame-retardant, flexible polyolefin that is selectively radiation cross-linked for reliable shrink performance. The inner wall is lined with a thermoplastic adhesive that flows during shrink to seal out moisture and contaminants while maintaining strong adhesion to the substrate. This 48-inch length in black is sold as a single piece and is appropriate for installation by electricians, automotive technicians, marine electricians, and industrial maintenance professionals.

This tubing is suited for use in automotive, truck fleet, marine, and industrial wiring applications. It performs well in environments where wire connections are exposed to moisture, vibration, or contaminants. Typical applications include inline wire splices, crimp splices, twisted pigtail splices, wire bundles, and wire harness breakouts. The nominal size is 0.5 inch diameter. The tubing meets application specification MIL-I-23053/4, Class 3, making it appropriate for use in environments that demand documented performance standards.

Key Features

• Dual-wall construction: flame-retardant polyolefin outer wall with internal thermoplastic adhesive liner
• Selectively radiation cross-linked outer wall for consistent, controlled shrink performance
• Adhesive layer seals against moisture, fluids, and contaminants after shrink
• Meets MIL-I-23053/4, Class 3 application specification
• Flexible construction suitable for wire bundle and harness breakout installations
• Black color, 48-inch length, 0.5-inch nominal diameter

Compatibility

Designed for use in automotive, truck fleet, marine, and industrial wiring applications involving inline splices, crimp splices, twisted pigtail splices, wire bundles, and wire harness breakouts where environmental sealing is required.

Installation Notes

Installation is typically performed by electricians or wiring technicians using a calibrated heat gun. Ensure the splice or connection is fully assembled and mechanically secure before applying the tubing. Apply heat evenly along the length of the tubing, working from the center outward, to allow the adhesive to flow uniformly and seal the connection. Do not use an open flame as the heat source, as uneven or excessive heat can damage both the tubing and the underlying conductors.
