3M 7000133617 Adhesive-lined Heat Shrink Tubing 3/4 in 48 in

Product Description

The 3M 7000133617 is an adhesive-lined, thin-wall heat shrink tubing designed for environmental protection and electrical insulation in demanding wiring applications. The outer wall is made from flame-retardant, flexible polyolefin that is selectively radiation cross-linked, and the inner layer is a thermoplastic adhesive that flows and bonds during the shrink process. At 3/4 inch diameter and 48 inches in length, this spool-cut piece suits a wide range of wire and connector sizes. Electricians, automotive technicians, and marine wiring specialists use this tubing to seal and protect splices, terminals, and harness breakouts. It meets MIL-I-23053/4, Class 3 specifications.

This tubing is well suited for protecting electronic components, twisted pigtail splices, inline wire splices, crimp splices, wire bundles, and wire harness breakouts. Typical applications span automotive, truck fleet, marine, and industrial wiring environments where moisture intrusion, vibration, and abrasion are ongoing concerns. The adhesive liner provides a watertight seal around irregular geometries that standard non-adhesive tubing cannot achieve. The 48-inch length is a standard cut piece suitable for bench work or field repair use.

Key Features

• Flame-retardant, flexible polyolefin outer wall with selective radiation cross-linking
• Internal thermoplastic adhesive liner delivers high adhesion and maintains flow during shrink
• Meets MIL-I-23053/4, Class 3 application specification
• 3/4 inch diameter suits mid-range wire bundles, crimp connectors, and harness breakouts
• 48-inch length provides usable stock for multiple field repairs from a single piece
• Standard black color for general-purpose electrical and automotive wiring

Compatibility

Designed for use on electronic components, pigtail and inline wire splices, crimp splices, wire bundles, and wire harness breakouts in automotive, truck fleet, marine, and industrial applications.

Installation Notes

Installation is typically performed by electricians, automotive technicians, or marine wiring specialists using a heat gun set to an appropriate shrink temperature for polyolefin tubing. De-energize all circuits and disconnect power before applying heat shrink over any splice or termination. Apply even heat around the full circumference of the tubing, working from the center outward, to allow the adhesive liner to flow uniformly and prevent air pockets. Avoid using an open flame, as it can scorch the outer wall and compromise the environmental seal.
