Heat Shrink Tubing Kit GEKO G02813 — 128 Pieces (various sizes) for Insulation and Cable Protection

GEKO G02813 — 128-piece heat shrink tubing kit provides a range of thermally shrinkable sleeves for electrical insulation, cable repair and mechanical protection. The set includes multiple diameters and lengths to cover common wiring tasks, offering reliable dielectric isolation and strain relief for splices, connectors and exposed conductors. Designed for general-purpose use in DIY projects, automotive wiring, electronics maintenance and household cable protection, the kit supplies a selection of sizes to reduce the need for individual purchases.

Advantages

The kit delivers a variety of heat shrink tubing sizes in one package, enabling rapid selection for different cable diameters. The tubing offers consistent shrink performance when heated, creating a tight, protective layer around wires and joints. It improves resistance to abrasion and light moisture penetration, helps prevent short circuits by insulating exposed conductors, and provides mechanical reinforcement at cable junctions to reduce stress on soldered or crimped connections.

Suitable for

• Electrical insulation of wire splices and solder joints
• Repairing damaged cable jackets and restoring protective covering
• Strain relief for connectors, terminals and wrapped joints
• Automotive wiring repairs and harness protection
• Hobby electronics, prototyping and DIY electrical projects

Key specifications

• Contents: 128 pieces of heat shrink tubing in multiple diameters and lengths
• Material: thermally shrinkable polymer (non-specified vinyl or polyolefin)
• Shrink ratio: suitable for common shrink applications (various ratios across sizes)
• Function: electrical insulation, mechanical protection and strain relief
• Color: typically black (other colors not specified in product data)

How to use

Select a tubing piece whose diameter when unshrunk comfortably fits over the connector or splice. Slide the tube over the joint before making the electrical connection if possible, or fit it over the prepared area and position it centered on the splice or exposed conductor. Apply heat evenly along the length of the tubing using a heat gun, hot air tool or carefully with a handheld lighter while keeping the flame at a safe distance; continue heating until the tubing contracts uniformly and forms a snug seal. Allow the tubing to cool before flexing the cable or reassembling equipment.

Usage recommendations

Use a heat gun or hot air tool for the most controlled and even shrinkage. Avoid direct prolonged flame contact to prevent scorching. Choose a tubing diameter that will shrink tightly around the conductor but still fit over connectors before heating. For added environmental protection, consider overlapping multiple pieces or combining with adhesive-lined tubing where moisture resistance is critical.
