3M 7010398863 Heat Shrink Tubing EPS300 3/8 in 48 in Black

Product Description

The 3M 7010398863 is a thin-wall heat shrink tubing from the EPS-300 series, designed to provide environmental protection and electrical insulation for wire and cable terminations. Each stick measures 48 inches in length with a 3/8-inch recovered diameter, and the black coloring aids in UV resistance and visual identification. This tubing is suited for use by electricians, HVAC technicians, and other trade professionals who need a reliable, low-profile shrink sleeve for wire splices, harness bundling, and terminal protection in exposed or moisture-prone environments.

The EPS-300 thin-wall tubing is commonly used in residential and light commercial electrical applications, including panel wiring, HVAC control wiring, and equipment harness repairs. Its thin wall profile allows for a clean finish in tight wiring runs where bulk is a concern. Sold individually by the stick, it is also available in a case quantity of 12 pieces for shops and service fleets stocking for regular use.

Key Features

• Thin-wall construction provides a low-profile, clean finish on wire and cable
• 48-inch stick length allows field cutting to required size
• 3/8-inch diameter suits a range of wire gauge and terminal sizes
• Black color aids UV resistance and cable identification
• EPS-300 series rated for environmental protection and electrical insulation

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve compatible with standard wire and cable termination applications where a 3/8-inch thin-wall shrink tube is specified.

Installation Notes

Installation is performed by electricians or qualified HVAC and controls technicians. De-energize all circuits before applying heat shrink tubing to any wiring. Use an appropriate heat gun set to the correct temperature range for the EPS-300 series — avoid open flame, which can cause uneven shrink or damage to adjacent insulation. Ensure the tubing is fully and evenly shrunk along its entire length before restoring power.
