Heating sleeve NEO tools 21-012 20 mm
Heating sleeve NEO tools 21-012 20 mm is a heat-shrink sleeve with a nominal 20 mm diameter intended for joining, insulating and protecting tubular components. Designed for controlled heat-shrink applications, it provides a uniform shrinkage profile to create sealed, mechanically stable connections in plumbing, automotive and electrical repair tasks. The sleeve is suitable for both professional workshops and DIY users requiring a compact, reliable solution for protective sealing of pipes, hoses and cable joints.
The sleeve offers consistent and even shrinkage that helps form a tight, protective layer around fittings and splices without excessive thinning. Its 20 mm nominal diameter matches common small-diameter tubular components, enabling a neat, low-profile finish. The material resists environmental factors typical for repair and maintenance tasks and simplifies assembly by minimizing manual fitting adjustments.
Slide the heating sleeve over the component or joint ensuring full coverage of the area to be sealed. Apply controlled heat using a heat gun, hot air tool or other suitable heat source, moving the heat source evenly around the sleeve until the material shrinks uniformly and forms a tight seal. Allow the sleeve to cool so the material sets and the joint stabilizes before subjecting it to mechanical or fluid pressure.
For best results, keep the heat source at an appropriate distance to avoid overheating, and ensure the work area is clean and free of oil or debris. Verify compatibility with the substrate material and use appropriate safety equipment when working with hot air tools.
