Product Information

Full details

This Sealey Heat Shrink Tubing Assortment is designed for professionals and DIY enthusiasts needing a reliable method for insulating, sealing, and protecting electrical connections. Its key benefit is providing a waterproof and moisture-resistant barrier with a 3:1 shrink ratio for a secure fit. A potential caveat is that the tubing comes in a fixed length of 200mm, which may require careful planning for longer applications. The assortment includes 72 pieces of red, adhesive-lined tubing in various sizes from Ø2.4mm to Ø12.7mm, suitable for a range of wire diameters.

Extended Product Information

FAQs

What is the shrink ratio of this tubing?

The tubing has a 3:1 shrink ratio, meaning it will shrink to one-third of its original diameter when heated.

What does 'adhesive lined' mean?

Adhesive lined means there is a layer of hot-melt adhesive on the inside of the tubing. When heated, this adhesive melts and flows, creating a waterproof and vibration-resistant seal.

What types of wires can I use this tubing on?

This tubing is suitable for most standard electrical wires, including those found in automotive, marine, and general electronic applications.

How do I determine the correct size to use?

Choose a piece of tubing whose original diameter is slightly larger than the diameter of the wire or connection you intend to cover. It should slide on easily before heating.

What heat source is recommended?

A heat gun is recommended for best results, providing even and controllable heat. A butane torch or a carefully applied lighter flame can also be used, but exercise caution to avoid scorching or burning the tubing.

What are the dimensions of the tubing pieces?

Each piece of tubing in this assortment is 200mm long. The diameters vary from Ø2.4mm up to Ø12.7mm.

Is this tubing suitable for outdoor use?

Yes, the adhesive lining creates a waterproof and moisture-resistant seal, making it well-suited for outdoor applications where connections may be exposed to the elements.

Troubleshooting

Tubing not shrinking evenly

Ensure heat is applied uniformly around the entire circumference of the tubing. Move the heat source back and forth and rotate the tubing frequently. Check that the heat source is at the correct temperature (above 90°C).

Adhesive is not sealing properly

Verify that the tubing is heated sufficiently for the adhesive to melt and flow. Ensure the wire surface under the tubing is clean and free from contaminants. Use the correct size tubing so it fits snugly.

Tubing shrinking too quickly or burning

Reduce the heat intensity or move the heat source further away from the tubing. Apply heat more gradually and continuously.

Tubing is too small to fit over the connection

Select a larger diameter heat shrink tubing from the assortment. Ensure the wire connection itself is not excessively bulky.

Pros and Cons

Pros

  • Provides a robust, waterproof seal for electrical connections.
  • High 3:1 shrink ratio ensures a tight, secure fit on various wire sizes.
  • Adhesive lining offers excellent protection against moisture and corrosion.
  • RoHS compliant, meeting industry safety and environmental standards.
  • Assortment includes a good range of common sizes for versatility.

Cons

  • Tubing length is fixed at 200mm, which might be insufficient for some longer applications without joining pieces.
  • Red color might not be suitable for all identification systems.
  • Requires a heat source (heat gun, lighter) for activation, which needs to be used carefully.

Setup, Compatibility & Care

Setup:

  1. Select the appropriate size of heat shrink tubing that is slightly larger than the diameter of the wire or connection you need to cover.
  2. Ensure the wire connection is clean and dry.
  3. Slide the heat shrink tubing over the connection, ensuring it extends past both ends of the exposed wires or splice.
  4. Using a heat gun on a medium to high setting (or a reliable lighter flame held at a distance), apply heat evenly around the tubing. Rotate the tubing and the heat source to ensure uniform shrinking.
  5. Continue heating until the tubing has shrunk tightly around the wire and the inner adhesive has melted and flowed, creating a seal. Avoid overheating, which can damage the wires or tubing.

Compatibility:

  • Compatible with most common electrical wire types, including copper and aluminum.
  • Requires a heat source capable of reaching at least 90°C (194°F) for optimal shrinkage.
  • The tubing is designed for use with electrical wiring and connections; not intended for high-pressure fluid systems or extremely high temperatures beyond its rating.

Care:

  • Store in a cool, dry place away from direct sunlight and excessive heat to maintain the adhesive's properties.
  • Keep the tubing organized to easily find the required size.
  • Ensure the tubing is applied correctly to maximize its lifespan and protective qualities.
