Heat Shrink Tubing Kit NEO tools 127 pcs (MPN 11-978)

NEO tools heat shrink tubing kit with 127 pieces provides a selection of heat-shrinkable sleeves in multiple diameters and lengths for insulating, protecting and organizing electrical connections. The set is intended for general electrical and electronic repair, cable management and strain relief. The assortment of tubing sizes and colors helps with insulation of joints, repair of damaged wire insulation and straightforward color-coding of wiring harnesses in workshop or field environments.

Advantages

The kit includes a broad range of tube diameters and lengths to cover different wire gauges and connector types, allowing consistent insulation and protection. Heat shrink material contracts reliably when heated, forming a tight sheath that improves mechanical strain relief and moisture resistance at splice points. Multiple colors in the set enable visual organization of cables and quicker identification during maintenance. The compact kit format keeps pieces sorted and ready for immediate use, suitable for technicians and hobbyists who require on-demand tubing variety.

Suitable for

• Insulating soldered or crimped electrical joints
• Repairing damaged or worn wire insulation
• Cable bundling and harness organization
• Providing strain relief on connector terminations
• Color-coding circuits for identification and maintenance

Key specifications

• Total number of pieces: 127 assorted tubes
• Variety of inner diameters to fit a range of wire gauges
• Different lengths to suit short splices and longer coverage needs
• Material: heat-shrinkable polymer (provides electrical insulation and mechanical protection)
• Shrink ratio: standard heat-shrink contraction for tight fit after heating
• Color assortment for visual identification
• Compact storage case for organized transport and storage

How to use

Select a tube with an inner diameter slightly larger than the wire or connector before shrinking. Slide the tube over the splice or area to be insulated, then apply heat evenly using a heat gun, lighter at a safe distance, or another controlled heat source until the tubing contracts uniformly around the conductor. Ensure the tubing covers the entire exposed conductor and overlaps slightly onto intact insulation to maintain a secure seal. Allow the tubing to cool before handling to ensure a stable, finished insulation layer.

Usage recommendations

Use a regulated heat gun at moderate temperature settings for the most consistent results and to avoid overheating surrounding components. For electrical connections that require environmental protection, consider using adhesive-lined heat shrink if moisture sealing is necessary. Match tube diameter to wire size and avoid applying excessive heat or open flame directly on sensitive components.
