3M 7100036089 Heat Shrink Tubing EPS300 1 in Black

Product Description

The 3M 7100036089 is a thin-wall heat shrink tubing designed for environmental protection and electrical insulation in wire and cable applications. Sold as the EPS-300 series, this tubing provides a durable sleeve that seals out moisture, contaminants, and abrasion from exposed conductors and connections. Each piece measures 6 inches in length with a 1-inch diameter. The pack contains 10 pieces. Licensed electricians and low-voltage technicians use this tubing during termination, splicing, and repair work where a clean, insulated finish is required.

This tubing is suited for residential and commercial electrical installations, panel work, and field splicing where wire ends or terminal connections need protected coverage. The EPS-300 series is a common choice in conduit runs, control wiring, and service entrance repairs where a compact, recoverable sleeve is needed. Its black color helps identify treated segments and resists UV degradation in exposed routing paths.

Key Features

• Thin-wall construction allows use in tight conduit fills and confined terminal areas
• EPS-300 series designed for environmental protection and electrical insulation
• 6-inch piece length suits standard splice and termination coverage
• Black color aids visual identification and provides UV resistance
• Sold in packs of 10 pieces for jobsite efficiency

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve for 1-inch diameter wire bundles, terminal connections, and cable splices in low-voltage and line-voltage electrical applications.

Installation Notes

Installation is performed by licensed electricians or qualified low-voltage technicians following NEC guidelines for insulation and termination work. De-energize all circuits before applying heat shrink tubing to any conductor or terminal. Use a calibrated heat gun at the manufacturer-recommended temperature range to achieve full recovery without scorching the tubing or adjacent insulation. Avoid open-flame sources, which can cause uneven shrinkage or damage to surrounding wire jackets.
