Heating sleeve 16 mm NEO tools 21-011

Heating sleeve 16 mm NEO tools 21-011 is a heat-shrink tube designed to provide electrical insulation, mechanical protection and environmental sealing for cable joints and terminations. The product is intended for use in household and light industrial installations where a compact heat-shrink solution is required. The 16 mm diameter fits common cable sizes and can be applied with a heat gun or, when appropriate, a lighter for small repairs.

Advantages

This heat-shrink sleeve offers reliable insulation and strain relief for repaired or extended cables, helping to protect conductors from short-circuits and moisture ingress. Its compact form factor enables accurate placement on joints and terminals, while the material provides a durable barrier against abrasion and environmental exposure. The sleeve is easy to handle and heats evenly under a controlled heat source, producing a tight, uniform shrink for long-lasting results.

Suitable for

• Cable repair and splice protection in household wiring
• Insulation of end-terminals and connectors
• Strain relief on small appliances and electrical devices
• Temporary or permanent sealing of exposed wiring in light industrial settings

Key specifications

• Nominal expanded diameter: 16 mm
• Material type: heat-shrinkable polymer (cross-linked)
• Primary functions: electrical insulation, mechanical protection, environmental sealing
• Application temperature: suitable for application with common heat guns or similar heat sources
• Typical shrink ratio: designed to provide tight conformal fit after heating

How to use

Prepare the cable or joint by ensuring surfaces are clean and free of grease or debris. Slide the heating sleeve over the joint so it fully covers exposed conductor and adjacent insulation. Apply heat evenly using a heat gun, moving the heat source back and forth to avoid overheating any single area. Continue heating until the sleeve uniformly contracts and conforms to the shape of the cable and connector. Allow the sleeve to cool to ambient temperature before handling.

Usage recommendations

For best results use a temperature-controlled heat gun and maintain a safe distance to prevent scorching. Avoid direct flame on the sleeve where possible; a lighter may be used for small emergency repairs but controlled, even heating is preferred. Choose the 16 mm sleeve when its diameter matches the expanded size of the cable bundle or joint to achieve optimal insulation and strain relief.
