Product Information

Full details

This Loops 1.2m Black Heat Shrink Tubing (16mm) is designed for professionals and DIY enthusiasts needing a robust, waterproof, and durable solution for cable management and protection. Its key benefit is the high 4:1 shrink ratio, allowing for easy application over connectors and providing a secure, long-lasting seal. A minor caveat is the requirement for a heat source, ideally a heat gun, to achieve optimal shrinkage.

FAQs

What is the shrink ratio of this tubing?

This tubing features a 4:1 shrink ratio, meaning it reduces from 16mm in diameter down to approximately 4mm when heated.

What is the minimum temperature required to shrink the tubing?

The minimum shrink temperature is 70°C. However, for optimal results and sealing, a temperature around 90°C is recommended.

Can I use a lighter or hair dryer to shrink this tubing?

While a lighter can be used for small applications, it may cause uneven heating or scorching. A hair dryer is generally not hot enough. A heat gun is the recommended tool for even and effective shrinkage.

What is the operating temperature range?

The tubing can operate reliably within a temperature range of -55°C to +125°C.

Is the adhesive lining waterproof?

Yes, the adhesive lining melts and flows when heated, creating a waterproof and electrically insulating seal.

What is the shrunk wall thickness?

The shrunk wall thickness is approximately 1.7mm.

What materials is this tubing made from?

The tubing is made from Polyolefin.

Troubleshooting

Tubing not shrinking sufficiently

Ensure the heat source is applied evenly and reaches the minimum shrink temperature (70°C). Try a higher heat setting or hold the heat gun closer for a longer duration.

Adhesive oozing out excessively

This can happen if overheated. While it ensures a good seal, try to use a slightly lower temperature or apply heat for a shorter, more controlled period.

Tubing appears to split or crack

This might occur if the tubing is stretched too thinly during application or if the heat is too concentrated on one spot. Ensure even heating and do not over-stretch the tubing before application.

Seal is not waterproof

Verify that the internal adhesive lining has fully melted and flowed to create a complete seal. Ensure the tubing overlaps sufficiently onto the cable jacket and connector body.

Pros and Cons

Pros

  • Provides a superior, durable, and waterproof seal compared to insulation tape.
  • High shrink ratio simplifies application over connectors, reducing labor.
  • Flame retardant and RoHS compliant for safety and environmental standards.
  • Suitable for a wide range of operating temperatures.
  • Heavy-duty construction offers excellent mechanical protection and cable bundling.

Cons

  • Requires a heat source (preferably a heat gun) for activation.
  • Shrunk wall thickness of 1.7mm might be too thick for very confined spaces.
  • Minimum shrink temperature of 70°C needs to be reached for proper function.

Setup, Compatibility & Care

Setup:

  1. Cut the heat shrink tubing to the desired length.
  2. Slide the tubing over the cable or component to be protected, ensuring it extends beyond the area needing sealing.
  3. Apply heat evenly using a heat gun. Start from the center and move outwards. The tubing will begin to shrink immediately. Continue heating until the tubing has fully conformed to the shape and a secure seal is achieved. For best results, aim for a temperature around 90°C.

Compatibility:

  • Compatible with most electrical wiring and cable types.
  • Designed to shrink over connectors and various irregular shapes due to its high shrink ratio.

Care:

  • Once applied, the heat shrink requires no special care.
  • Avoid exposing the sealed area to excessive physical abrasion or sharp objects that could compromise the integrity of the tubing.
