Value Collection BD-23639-B Heat Shrink Sleeve 1 in Id Black

Product Description

The VALUE COLLECTION BD-23639-B is a black heat shrink sleeve designed to protect and insulate electrical wire terminations and splices. With a 1 inch inside diameter before shrinking and an overall length of 1.5 inches, this sleeve applies heat to conform tightly around conductors and connection points. Compatible with wire sizes from 3/0 AWG to 4/0 AWG, it suits heavy-gauge electrical work common in industrial, commercial, and utility installations. Electricians and maintenance technicians use this sleeve to seal connections against moisture ingress, abrasion, and environmental exposure. The compact length makes it well suited for terminal lugs, butt splices, and ring connectors on large-gauge wiring.

This heat shrink sleeve is appropriate for use in residential service entrance work, commercial electrical panels, industrial control wiring, and marine or outdoor environments where conductor protection is critical. Its 1 inch pre-shrink ID accommodates the large conductor diameters typical of 3/0 and 4/0 AWG cable. Electricians reaching for a reliable, single-use sleeve for large-format terminations will find this a straightforward fit for standard heat shrink application workflows.

Key Features

• 1 inch inside diameter before shrinking accommodates 3/0 to 4/0 AWG wire
• 1.5 inch overall length sized for terminal lugs and short splice protection
• Black color for standard color-coding and UV-light resistance in typical installs
• Heat-activated shrink provides a snug, moisture-resistant fit over the conductor
• Lightweight at 0.01 pounds per piece, easy to carry in quantity on the job

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve for heavy-gauge electrical conductors ranging from 3/0 AWG to 4/0 AWG in residential, commercial, and industrial wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified electrical technicians. De-energize and lock out the circuit before applying any sleeve to a conductor or termination. Position the sleeve over the connection point and apply even heat using a heat gun, working from the center outward to avoid air pockets. Do not use an open flame as a heat source, as uneven heat can damage the sleeve or underlying insulation.
