3M 7010398878 Heat Shrink Polyolefin Tubing 3/8 in 6 in

Product Description

The 3M 7010398878 is a flexible polyolefin heat shrink tubing designed to protect electronic components, wire splices, and wire bundles in electrical and electronic assemblies. Constructed from a dual-wall-style polyolefin material, this tubing conforms tightly to irregular surfaces when heat is applied, forming a durable insulating sleeve. At 3/8 inch diameter and 6 inches in length, it suits a range of light-duty wiring tasks encountered by electricians, electronics technicians, and field service professionals. The black finish helps with identification and provides basic UV resistance in exposed installations.

This tubing is suited for use in residential and commercial electrical work, low-voltage control wiring, automotive wiring harnesses, and electronic equipment repair. It is commonly applied over wire splices, terminal connections, and component leads where mechanical protection and electrical insulation are both required. The 6-inch length makes it practical for individual splice protection without cutting from a longer roll. It ships in a pack with a minimum order quantity of 10 pieces.

Key Features

• Flexible polyolefin construction conforms to irregular wire and component shapes after heat application
• 3/8 inch recovered diameter suits a variety of wire gauges and small bundle sizes
• 6-inch pre-cut length ready for immediate use on individual splices or terminals
• Black color aids circuit identification and provides basic UV resistance
• Lightweight at 0.11 pounds per pack, minimizing added bulk in tight wire runs

Compatibility

Designed as an OEM-style heat shrink sleeve for general electrical and electronic wiring applications requiring flexible polyolefin insulation at 3/8 inch diameter.

Installation Notes

Installation is performed by licensed electricians or electronics technicians. De-energize all circuits completely before sliding tubing over the splice or component and applying heat. Use a heat gun set to the appropriate recovery temperature for polyolefin tubing and apply heat evenly along the length of the sleeve. Avoid open flame, as direct flame contact can damage the tubing and underlying conductors.
