3M 7000148860 Heat Shrink Polyolefin Tubing EPS400 0.350 in

Product Description

The 3M 7000148860 is a multiple-wall polyolefin heat shrink tubing in the EPS-400 series, designed to provide environmental protection for electrical and electronic applications. It ships in 48-inch sticks and carries a nominal recovered diameter of 0.350 inches. The multiple-wall construction combines an outer polyolefin jacket with an inner adhesive lining that flows on recovery, sealing out moisture, contaminants, and mechanical stress. Electricians and harness technicians rely on this tubing for demanding wire protection work where a single-wall tube is not sufficient.

This tubing is suited for use on wire splices, wire bundles, harness breakouts, and exposed electronic components in residential, commercial, and industrial electrical installations. It is a common choice in control panel wiring, automotive harness repair, and low-voltage field wiring applications where long-term moisture resistance is a priority. Each piece measures 48 inches in length, providing flexibility for field cutting to length on a variety of termination sizes.

Key Features

• Multiple-wall construction with internal adhesive liner for moisture-resistant sealing
• Polyolefin outer wall provides flexibility and resistance to abrasion after recovery
• 48-inch stick length allows field trimming to fit varied splice and bundle sizes
• 0.350-inch nominal diameter accommodates a range of wire bundle and connector sizes
• Sold individually; minimum order quantity is 12 pieces per order

Compatibility

Designed as an OEM-style heat shrink solution for protecting wire splices, harness breakouts, and electronic component terminations in electrical and electronic assemblies.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians. Power down and de-energize any circuit before applying heat shrink tubing over splices or terminations. Use a calibrated heat gun set to the appropriate recovery temperature for polyolefin materials; open flame torches are not recommended, as uneven heat can cause incomplete adhesive flow or jacket damage. Follow applicable NEC guidelines for wire splice insulation and protection requirements.
