3M 7010350271 EPS300 Heat Shrink Tubing 1/2 in Black 3-pc

Product Description

The 3M 7010350271 is a thin-wall heat shrink tubing sold under the EPS-300 product line, designed for environmental protection and electrical insulation of wire splices, terminals, and connections. Each piece measures 6 inches in length with a 1/2-inch diameter. The tubing is black and ships in packs of 3 pieces. EPS-300 tubing is rated for dual-wall-style environmental sealing performance in a thin-wall form factor, making it a practical choice for electricians and low-voltage installers who need reliable insulation without the bulk of adhesive-lined alternatives.

This heat shrink tubing is used in residential and commercial electrical work, panel wiring, automotive harness repair, and industrial control wiring. It is well suited for protecting exposed conductor ends, insulating butt splices, and bundling wire runs where a clean, durable finish is required. Electricians, instrumentation techs, and OEM assembly operations commonly use EPS-300 tubing where environmental protection and dielectric insulation are both needed in a single step.

Key Features

• Thin-wall construction provides insulation and environmental protection without excessive bulk
• 6-inch piece length allows for versatile cutting to application-specific lengths
• 1/2-inch diameter fits a range of wire gauges and terminal sizes
• Black color aids in identification and provides UV resistance typical of black polyolefin materials
• Packaged 3 pieces per pack with a minimum order quantity of 10 packs per case

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve for electrical insulation and environmental protection applications across residential, commercial, and industrial wiring systems.

Installation Notes

Licensed electricians and low-voltage technicians typically install heat shrink tubing using a heat gun set to the appropriate shrink temperature for the tubing material. Power down and de-energize all circuits before applying tubing to any splice or terminal. Slide tubing onto the conductor before making the connection, then position and apply heat evenly along the length to achieve uniform shrink. Do not use an open flame as the heat source, as uneven heat can damage the tubing or underlying insulation.
