Heat-shrink tubing assortment Delock WKK 281111201 — polyolefin, multicolour, 127-piece set

Delock WKK 281111201 is a 127-piece assortment of polyolefin heat-shrink tubing in multiple colours. The set contains H-2(Z) heat-shrink sleeves in a range of diameters and lengths to insulate, protect and repair electrical connections, cables and solder joints for electronics, automotive wiring and general cable management.

Advantages

The assortment offers a broad selection of sizes and seven colours to match different wiring and identification needs. Made from polyolefin, the heat-shrink tubing provides electrical insulation, mechanical protection and moisture resistance after shrinking. The compact set keeps multiple commonly used tube sizes available in one kit for convenient repair and assembly work.

Suitable for

• Insulating soldered joints and wire splices
• Protecting and identifying automotive wiring
• Cable management and strain relief for small electronics
• General electrical repairs and prototypes

When it may not be suitable

This assortment is intended for general-purpose electrical insulation and protection; it is not designed for high-voltage or heavy industrial power applications where thicker, specialized or certified tubing is required. Very large-diameter cables or applications that require thermal, chemical or flame-retardant specifications beyond standard polyolefin may need alternative products.

Key specifications

• Material: polyolefin
• Quantity: 127 pieces
• Colour: multicolour (seven colours/types)
• Type: H-2(Z) heat-shrink tubing

How to use

Select a sleeve with a pre-shrink diameter slightly larger than the component to be covered. Slide the tubing over the connection, then apply heat evenly using a heat gun, hot air tool or lighter at a safe distance until the tubing contracts and conforms to the underlying shape. Allow to cool so the tubing hardens and secures the joint.

What to consider before purchase

• Verify that polyolefin material and the available diameters meet your electrical and mechanical requirements
• Confirm the set includes the specific sizes you need for your projects
• Consider if you require heat-shrink tubing with higher temperature, chemical or flame resistance

Usage recommendations

For consistent results, use a regulated heat gun and apply heat evenly while keeping the tool moving to avoid overheating; test fit the correct diameter before shrinking and allow components to cool undisturbed after application.
