SPIDER Automation | PVC Heat Shrink Sleeve – 50mm, 1 Meter | Sky Blue Lithium Battery Pack Insulation & Protection
Product Overview & Material Technology
The PVC Heat Shrink Sleeve is designed for covering, insulating and protecting lithium battery cell packs and compatible electrical assemblies. Its 50mm stated diameter makes it suitable for applications requiring a medium-format heat-shrink covering.
Manufactured from Polyvinyl Chloride (PVC), the sleeve provides an external insulating layer and mechanical protection for covered assemblies. When exposed to suitable heat, it shrinks around the battery pack or electrical assembly to create a closer-fitting protective cover. This helps hold battery pack components together while improving the overall appearance of the finished assembly.
The sleeve also supports applications involving sealing, strain relief and component identification. Its sky blue colour provides a clear visual distinction for battery packs, wires and electrical components, helping maintain organised wiring and a professional finish.
Supplied in a 1-meter continuous length, the sleeve can be cut according to the required application. Installation can be performed using a suitable hair dryer or heat gun, with controlled heating to achieve an even fit around the assembly.
Technical Features & Performance Characteristics
- 50mm Stated Diameter: Designed for compatible battery packs, wire bundles and electrical assemblies requiring a 50mm sleeve.
- PVC Material Construction: Made from Polyvinyl Chloride, providing an insulating outer covering for suitable electrical applications.
- Heat-Shrink Function: Contracts around the covered assembly when exposed to suitable heat.

Installation & Operating Recommendations
- Check the Assembly Size: Confirm the battery pack or cable bundle dimensions and ensure the sleeve is suitable before installation.
- Cut to Required Length: Cut the sleeve to provide adequate coverage for the intended assembly.
- Position the Sleeve: Slide the sleeve over the battery pack or cable assembly and align it before applying heat.
- Apply Controlled Heat: Use a suitable hair dryer or heat gun, distributing heat gradually around the sleeve for an even fit.
- Protect Sensitive Components: Avoid overheating battery cells, wires and nearby components. Follow the battery manufacturer’s temperature limits.
- Inspect After Installation: Allow the assembly to cool and check that the sleeve is fitted evenly and has no visible damage.
