3M 7000148859 Heat Shrink Polyolefin Tubing EPS400 0.300 in

Product Description

The 3M 7000148859 is a multiple-wall polyolefin heat shrink tubing from the EPS-400 series, designed to provide environmental protection for electronic components, wire splices, wire bundles, and harness breakouts. Each stick measures 48 inches in length with a recovered diameter of 0.300 inches. The multiple-wall construction combines an outer polyolefin jacket with an inner adhesive liner that flows when heated, sealing out moisture, contaminants, and mechanical stress. This tubing is commonly installed by electricians and electronics technicians working on wire harness assemblies, splice protection, and breakout sealing in automotive, industrial, and marine environments.

The EPS-400 tubing is suited for applications requiring a durable, sealed termination on wire bundles and harness breakouts in both residential and commercial electrical work. Its 48-inch stick format is practical for bench-top harness assembly and field service repairs where consistent, repeatable shrink performance is needed. Minimum order quantity is 12 pieces per case.

Key Features

• Multiple-wall polyolefin construction with integral adhesive inner wall for moisture-sealing performance
• 48-inch stick length allows cutting to custom lengths on the job
• 0.300-inch recovered diameter fits a range of wire bundle sizes
• Protects wire splices, harness breakouts, and electronic components from environmental exposure
• Sold individually; minimum order quantity of 12 pieces

Compatibility

Designed as an OEM-style replacement and general-use heat shrink solution for wire harness protection and splice sealing applications in electrical and electronics assembly work.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians. Power down and de-energize all circuits before applying heat shrink tubing to any wire assembly. Use a calibrated heat gun set to the appropriate temperature range for polyolefin materials — do not use an open flame, as this can cause uneven shrinkage or damage the adhesive liner. Ensure the tubing is fully slid over the splice or breakout before applying heat, and work from the center outward to prevent air pockets.
