3M 7010350255 Heat Shrink Polyolefin Tubing 0.300 in Black

Product Description

The 3M 7010350255 is a multiple-wall polyolefin heat shrink tubing designed to provide environmental protection for electronic components, wire splices, wire bundles, and harness breakouts. The EPS400 series tubing is manufactured in black and ships in 6-inch lengths, sold in packs of 10 pieces. Multiple-wall construction delivers both structural support and sealing capability in a single step, making it well suited for demanding electrical and electronic assembly applications where moisture, abrasion, or contamination are concerns.

This tubing is used in electrical and electronic service work where wire splices and harness terminations require durable insulation and environmental sealing. It is a common choice for automotive, marine, industrial, and low-voltage electrical wiring applications. Licensed electricians, electronics technicians, and harness assembly professionals install this product during new builds, repairs, and field service work.

Key Features

• Multiple-wall polyolefin construction provides combined insulation and environmental sealing
• 6-inch cut lengths allow precise placement on splices and harness breakouts
• Black finish for standard identification and UV resistance typical of polyolefin tubing
• Sold in packs of 10 pieces for jobsite or shop use
• Lightweight at 0.11 pounds per pack, suitable for mobile or field kit storage

Compatibility

Designed as an OEM-style replacement and general-use heat shrink solution for wire splices, electronic component leads, wire bundles, and harness breakout points requiring environmental protection.

Installation Notes

Heat shrink tubing of this type is installed by electricians and electronics technicians using a heat gun set to the appropriate shrink temperature for polyolefin materials. Always de-energize the circuit before applying tubing to any splice or termination. Slide tubing over the conductor or splice before making the connection, then apply heat evenly along the length to achieve a uniform shrink. Follow applicable NEC guidelines for insulation requirements at the voltage and environment of the installation.
