Value Collection BD23621 Heat Shrink Sleeve 3/8 in 6 in

Product Description

The VALUE COLLECTION BD23621 is a black heat shrink sleeve designed to protect wire splices, terminals, and cable bundles in electrical and low-voltage wiring applications. With a pre-shrink inside diameter of 3/8 inch and an overall length of 6 inches, this sleeve provides a snug, insulating fit when heat is applied. The sleeve conforms tightly around the substrate as it shrinks, creating a protective barrier against moisture, abrasion, and accidental contact. Electricians, HVAC technicians, and panel wiring professionals use heat shrink sleeves as a standard method for securing and insulating wire connections during installation and service work.

This sleeve suits residential and light commercial wiring tasks where a clean, durable termination is required. Common applications include insulating butt splices, covering exposed conductor ends, protecting low-voltage control wiring connections, and bundling small wire groups. The 6-inch length allows the installer to cut sections to the needed length for a given connection, reducing waste on shorter terminations. The black color provides a neutral finish compatible with most wiring assemblies.

Key Features

• 3/8 inch inside diameter before shrinking — suitable for mid-range wire gauges and bundled conductors
• 6 inch overall length allows cutting to size for varied connection lengths
• Black color provides a clean, neutral appearance in finished wiring assemblies
• Heat shrink construction conforms tightly to the substrate when heat is applied
• Lightweight at 0.01 pounds — easy to stock and carry in a service bag or van

Compatibility

Designed as a general-purpose heat shrink sleeve for standard electrical wiring and low-voltage control applications where a 3/8 inch pre-shrink inside diameter and 6 inch length are appropriate.

Installation Notes

Heat shrink sleeves are installed by licensed electricians and HVAC technicians following applicable NEC guidelines. De-energize the circuit completely before working on any wiring connection. Slide the sleeve over the conductor or splice before making the final connection, then position it over the finished joint and apply even heat with a heat gun until the sleeve conforms fully. Do not use an open flame as a heat source, as uneven heat can damage the sleeve or surrounding insulation.
