Heating sleeve 90 mm NEO tools 21-019

Heating sleeve 90 mm NEO tools 21-019 is a heat-shrink sleeve designed to insulate and protect joints, cable splices and pipe connections with a nominal diameter of 90 mm. Made for use in electrical and plumbing applications, the sleeve provides mechanical protection and electrical insulation after heat application, forming a tight, durable covering that resists moisture and wear during repair, maintenance and installation work.

Advantages

The sleeve delivers reliable shrink performance that creates a neat and long-lasting seal around joints and connections. Its construction ensures consistent electrical insulation and improved mechanical protection compared with untreated splices. The product is straightforward to apply with a heat source, conforms to irregular shapes, and reduces the risk of exposure to moisture and contaminants at the connection point.

Suitable for

• Insulating cable splices and wire joints
• Sealing and protecting small pipe or conduit connections
• Repairing and reinforcing worn insulation on electrical harnesses
• Maintenance work where moisture resistance and mechanical protection are required

Key specifications

• Nominal diameter after application: 90 mm
• Type: heat-shrink sleeve for insulation and protection
• Primary functions: electrical insulation, mechanical protection, moisture resistance
• Application method: heat shrink using a heat gun or equivalent heat source
• Suitable environments: indoor and sheltered outdoor installations

How to use

Position the sleeve over the joint or connection so that it fully covers the area to be insulated. Apply controlled heat with a heat gun or other suitable heat source, moving the heat evenly around the sleeve until it shrinks and conforms tightly to the underlying components. Allow the sleeve to cool and verify that the sleeve is fully adhered and that no gaps remain. Trim any excess material if necessary after cooling.

Usage recommendations

For best results, use a regulated heat gun and keep the heat source moving to prevent overheating. Ensure surfaces are clean and free of oil, dirt or corrosion before applying the sleeve. Verify suitability for the specific cable or pipe materials and operating temperatures prior to long-term installation.
