Heat shrink tubing 35/11 KTK-33/11

Heat shrink caps – reliable connection protection

Heat shrink caps are an indispensable element in the work of every electrician and installer, but also useful for DIY enthusiasts who care about the safety and durability of electrical connections. They are used to seal the ends of cables and wires, providing effective protection against moisture, corrosion, chemicals and mechanical damage. The KTK-33/11 model, made of polyolefin (PO-X), is characterized by high flexibility and durability.

Construction and properties

This heat shrink cap is characterized by a shrinkage ratio of 3:1, which means that after heating it reduces its diameter by more than 66%. Before shrinking, it has an inner diameter of 33 mm, and after shrinking 14.6 mm. This allows it to perfectly adapt to different sizes of wires and cables. The inner layer of hot-melt adhesive further strengthens the insulation seal, creating a protective barrier against external factors. The cap is halogen-free, which increases safety and minimizes the risk of toxic substances forming during combustion. Designed to operate in a wide temperature range from -45°C to +110°C. The black color makes it easy to identify and provides a discreet look.

Application and benefits

• Protection against corrosion: Hot-melt adhesive fills all gaps, preventing moisture and chemicals from accessing the wires.
• Electrical insulation: Provides high electrical insulation, minimizing the risk of short circuits and electric shock.
• Strengthening connections: Protects screws and connections from mechanical damage and weather conditions.
• Versatility: Suitable for sealing power and telecommunication cables of various types.
• Easy installation: Simply heat the cap with a heat gun or heat blower to fit the shape of the wire.
• Safety: Halogen-free material ensures safe use and minimizes the emission of harmful substances in the event of a fire.
• Durability: Made of high-quality polyolefin (PO-X) guarantees long-lasting protection of connections.

This cap is a solid solution for both professionals and home users who value the safety and reliability of electrical installations.
