Heat shrink tube Ergom Kapturek KTK 33 15 mm

Heat shrink tube Ergom Kapturek KTK 33 15 mm is a flexible polyolefin sleeve designed to provide electrical insulation, mechanical protection and strain relief for cables and connectors. With an initial diameter of 15 mm, this heat shrink tubing reduces in diameter when heated to create a close-fitting, durable cover that prevents moisture ingress and protects against abrasion and minor impacts. It is suitable for repair work, cable bundling and finishing exposed connections in automotive, industrial and domestic settings.

Advantages

The heat shrink tube offers reliable insulation and enhanced mechanical protection after shrinking, forming a uniform, tight layer around wires and joints. Its material resists common environmental factors such as humidity and light abrasion, while remaining flexible enough to conform to irregular shapes. The product is easy to cut to length and apply with a standard heat source, producing a neat, professional finish that improves cable appearance and prolongs component life.

Suitable for

• Insulating and protecting splices and soldered joints
• Cable bundling and organizing wiring looms
• Strain relief at connector entry points
• Repairing damaged outer insulation on cables
• Electrical and electronic maintenance in vehicles, machines and home appliances

Key specifications

• Material: heat-shrink polyolefin
• Initial nominal diameter: 15 mm (before shrinking)
• Shrink ratio: commonly 2:1 or higher typical for this type of tubing (forms tight seal when heated)
• Flexible and abrasion-resistant after shrinking
• Provides electrical insulation and moisture resistance

How to use

Cut the heat shrink tube to the required length so that it fully covers the defect, splice or connector with a small overlap. Slide the tube into position and apply heat evenly along its length using a heat gun, hot air tool or controlled flame at a safe distance until the tubing contracts and forms a snug fit. Allow the sleeve to cool naturally so the material sets and creates a stable protective layer. Do not overheat or apply direct flame too closely to avoid damage to insulation or nearby components.

Usage recommendations

Select a heat source that allows controlled, even heating and keep a safe distance to avoid scorching surrounding materials. Measure the cable or bundle before shrinking to ensure the initial diameter provides sufficient coverage and shrinkage. For environmental sealing in wet conditions, ensure full contraction and consider using adhesive-lined variants where a waterproof bond is required.
