Krympeflex DeLOCK 19591

The DeLOCK 19591 heat shrink tube is made from durable polyolefin and comes in red. Designed to provide insulation and mechanical protection, the tube contracts when exposed to heat to form a tight, protective sleeve around grips, wires or connections. It helps reduce the effects of moisture, abrasion and weather on treated surfaces and is suitable for a variety of grips and cable applications.

Advantages

The polyolefin construction offers reliable shrink performance and resistance to abrasion. With a 2:1 shrinkage ratio the tube reduces to approximately half its original diameter under heat, producing a close fit. The red colour improves visibility for identification, and the material provides basic protection against moisture and mechanical wear.

Suitable for

• Tool handles and non-slip grips
• Fitness equipment and sports handles (e.g., tennis rackets)
• Fishing rods and outdoor gear
• Insulating and protecting electrical joints and cable repairs
• General cable management and bundling

How to use

Slide the heat shrink tube over the item to be covered, ensuring it fully overlaps the area requiring protection. Apply heat evenly using a hot air gun until the tube shrinks uniformly to about half its original diameter and forms a tight seal. Allow the sleeve to cool before handling. For smaller components, a heat source with controlled temperature is recommended to avoid overheating adjacent parts.

Recommendations

For consistent results, maintain a steady distance between the heat source and the tube while rotating the item when possible. Avoid open flames and use a hot air gun with adjustable temperature to prevent damage to surrounding materials.
