3M 7010293960 Heat Shrink Polyolefin Tubing 0.350 in Black

Product Description

The 3M 7010293960 is a multiple-wall polyolefin heat shrink tubing designed for durable environmental protection of electronic components, wire splices, wire bundles, and harness breakouts. Each piece measures 6 inches in length with a 0.350-inch diameter. The multiple-wall construction provides both a structural outer layer and an inner adhesive or sealant layer that bonds and seals when heat is applied, delivering moisture resistance and mechanical protection in demanding electrical and electronic installations. This product is sold in packs of 10 pieces and is suited for electricians, electronics technicians, and wire harness assemblers working in industrial, commercial, or automotive-style wiring applications.

This tubing is used in residential and commercial electrical work, panel wiring, field wire repair, and harness fabrication where long-term protection against moisture, contaminants, and abrasion is required. It is well suited for connector backshells, wire bundle transitions, and splice protection in control panels, equipment wiring, and low-voltage harness assemblies. The 6-inch cut length provides a practical working size for most splice and termination applications without trimming.

Key Features

• Multiple-wall polyolefin construction provides both structural protection and interior sealing when heated
• 6-inch cut lengths for straightforward splice and termination coverage
• 0.350-inch diameter fits a range of wire bundle and connector sizes
• Black color for identification and UV-resistance in exposed wiring runs
• Sold in a 10-piece pack for job-site use or bench stock replenishment

Compatibility

Designed as an OEM-style replacement and general-use heat shrink tubing for electronic component protection, wire splices, wire bundles, and harness breakouts in electrical and low-voltage applications.

Installation Notes

Installation is performed by electricians or electronics technicians familiar with heat shrink tooling and applicable wiring codes such as NEC requirements for splice and termination protection. De-energize all circuits completely before applying heat shrink tubing to any splice or conductor. Use a calibrated heat gun rather than an open flame to achieve even shrink and proper adhesive flow without scorching the tubing or adjacent insulation. Verify the tubing has fully cooled and the inner wall has bonded before restoring power or closing enclosures.
