Black Heat Shrink Tubing, 3/64" Diameter x 12" Length

Protect and finish small electrical connections with black heat shrink tubing designed for precision wiring and repair applications. Measuring 3/64 inch in diameter and approximately 12 inches (30 cm) long, this compact tubing is ideal for covering small wires, insulating suitable connections, and providing a neat, professional appearance to electronic assemblies.

Heat shrink tubing is a convenient solution for applications where electrical insulation, wire identification, or added protection is needed. When heated according to the tubing's specifications, it contracts around the underlying wire or component to create a close-fitting protective covering.

The small 3/64-inch diameter makes this tubing particularly useful for fine-gauge wiring and miniature electrical assemblies. It provides a practical alternative to bulky wrapping materials when working in confined spaces or on delicate projects.

The black finish offers a clean, uniform appearance that blends naturally with many electronic cables, wiring harnesses, and equipment interiors. It is especially useful for maintaining a consistent appearance across repairs and custom assemblies.

Supplied in an approximately 1-foot length, the tubing can be cut into smaller sections to suit individual applications. This makes it convenient for occasional repairs, electronics projects, and precision maintenance tasks where only a small amount of material is needed.

Compact 3/64-Inch Diameter

The 3/64-inch nominal diameter makes this tubing suitable for applications involving very small wires and components.

This size is particularly useful when larger heat shrink tubing would create unnecessary bulk.

Before installation, confirm that the tubing can slide over the wire, splice, or component that needs to be covered.

The nominal diameter describes the tubing before shrinking. The final recovered diameter depends on the product's shrink characteristics.

For the best fit, choose tubing that accommodates the largest section of the assembly before heating and can contract sufficiently around the smaller sections.

Convenient 12-Inch Length

Each piece measures approximately 1 foot (30 cm) long.

The tubing can be cut into shorter sections for individual connections, repairs, and small projects.

This allows you to use only the amount required for each application.

For example, a short section may be sufficient to cover a small soldered connection, while a longer section may be appropriate for protecting an exposed portion of wire.

Measure the area to be covered before cutting, allowing sufficient overlap onto the surrounding insulation.

Clean Black Finish

The black color provides a discreet appearance for wiring repairs and custom assemblies.

It is especially useful when working with black cables, electronic equipment interiors, and wiring harnesses.

A properly fitted section of heat shrink tubing can create a cleaner finish than loosely wrapped insulating material.

The smooth tubular form also helps keep individual wire sections neatly covered.

Electrical Connection Protection

Heat shrink tubing is commonly used to cover soldered connections and other suitable electrical joints.

Once installed correctly, the tubing provides an additional protective covering over the connection.

It can help reduce accidental contact with exposed conductive surfaces and protect the covered area from minor handling wear.

For electrical applications, verify that the tubing's insulation properties and voltage rating are appropriate for the equipment.

Do not rely on tubing with an unspecified electrical rating for safety-critical insulation.

Precision Electronics Applications

Small heat shrink tubing is particularly useful in electronics repair and assembly.

Its compact diameter makes it suitable for many fine-wire applications where larger sleeving may be impractical.

It can be used to finish wire repairs, protect suitable connections, and maintain a tidy appearance inside equipment.

When working around sensitive electronic components, apply heat carefully to avoid damaging nearby insulation, plastics, connectors, or circuit board materials.

Always disconnect equipment from power before performing electrical repairs.

How to Use Heat Shrink Tubing

1. Select the correct size. Confirm that the tubing will fit over the wire or connection before heating.

2. Cut to length. Trim a section long enough to cover the desired area with suitable overlap.

3. Position the tubing. Slide it over the wire before completing a connection when necessary.

4. Complete the connection. Make sure the underlying electrical joint is secure and properly prepared.

5. Move the tubing into place. Center it over the area requiring coverage.

6. Apply controlled heat. Use an appropriate heat source and follow the tubing manufacturer's temperature recommendations.

7. Allow it to cool. Let the tubing cool before handling or placing the assembly back into service.

8. Inspect the result. Check that the tubing has formed a consistent covering without splitting, scorching, or leaving exposed areas.

Avoid using an open flame, which can overheat or damage the tubing and surrounding components.

Choosing the Right Tubing Size

Heat shrink tubing should be selected according to both the size of the wire or component and the amount of shrinkage required.

The tubing must be large enough to slide into position before heating.

It must also be capable of contracting sufficiently to provide the desired fit.

Because the shrink ratio for this specific product is not stated, verify suitability before using it for applications requiring a particular recovered diameter.

Storage and Handling

Store unused tubing in a clean, dry location away from excessive heat and direct sunlight.

Keep it free from dirt, oil, and other contaminants that could interfere with installation.

Use sharp cutting tools to produce clean, even ends.

Avoid stretching or damaging the tubing during installation.

Apply heat evenly and carefully to prevent scorching or damage to nearby components.
