Heat Shrink Tubing Set Forcekraft FK-820 — 127 Pieces, Assorted Sizes

Forcekraft FK-820 is a 127-piece heat shrink tubing set that provides a range of heat-shrinkable sleeves in assorted sizes for electrical insulation, wire repair and cable protection. The kit contains multiple diameters and lengths to fit common wire gauges and connector joints, enabling neat insulation, strain relief and protection of small harnesses in electronics, automotive and household applications.

Advantages

The set offers a broad selection of tube sizes in a single kit, reducing the need to purchase individual pieces. Made from heat-shrinkable polymer, the sleeves provide reliable electrical insulation and conform closely to irregular shapes when heated, improving mechanical stability and moisture resistance of connections. The assortment simplifies identification and selection for various wire diameters and repair tasks.

Suitable for

• Insulating spliced wires and connector joints
• Repairing damaged insulation on cables
• Providing strain relief for soldered or crimped connections
• Bundling and protecting small wiring harnesses in electronics and automotive systems

Key specifications

• Contents: 127 pieces in assorted diameters and lengths
• Material: heat-shrinkable polymer for electrical insulation
• Shrink ratio: suitable for standard wire repair and insulation tasks
• Operating temperature range: designed for typical electronics and automotive environments
• Colour: assorted (commonly black and mixed colours for identification)

How to use

Select a sleeve with an initial inner diameter slightly larger than the component or wire bundle to be covered. Slide the tubing over the joint, splice or cable, then apply controlled heat using a heat gun, lighter or other heat source until the tubing contracts evenly and adheres to the surface. Allow the tubing to cool so it forms a secure insulating layer; trim excess material as needed for a neat finish.

Usage recommendations

For consistent results, use a temperature-controlled heat gun and heat gradually from one end to the other. Avoid direct flame on sensitive components; maintain an appropriate distance to prevent overheating. Choose tubing with an adequate wall thickness and shrink ratio for the expected mechanical and thermal stresses.
