Sealey Heat Shrink Tubing - 200mm - 100 Pieces - Red - HST200R

A 2:1 shrink ratio means the tubing will shrink to half of its original diameter when heated. For example, tubing with an initial diameter of 6.4mm will shrink to approximately 3.2mm.

The tubing generally requires a temperature of around 90°C to initiate shrinkage. The exact temperature can vary slightly based on the heat source and application.

A heat gun is the recommended tool for even and controlled shrinking. A lighter can be used with caution for small applications, but care must be taken not to scorch or burn the tubing.

Select a tubing size where the unshrunk diameter is slightly larger than the component or wire bundle you need to cover, allowing it to slide on easily before heating.

The tubing provides electrical insulation and protection. While it offers some environmental resistance, prolonged exposure to harsh UV or extreme weather conditions may degrade the material over time.

Yes, it is suitable for insulating and protecting automotive electrical connections, provided the operating temperatures are within the tubing's limits.

RoHS (Restriction of Hazardous Substances) compliance means the product adheres to directives limiting the use of specific hazardous materials in electrical and electronic equipment, ensuring it meets environmental and safety standards.

Ensure heat is applied evenly and consistently around the tubing. Rotate the tubing as you apply heat. Check that the heat source is sufficient for the tubing size.

Reduce the heat temperature or the duration of heat exposure. Keep the heat source moving to prevent overheating one area. Ensure the heat source is at an appropriate distance.

The selected tubing diameter may be too small for the wire or connection. Ensure you are using a size that allows for initial fitment before heating.

Ensure the surface to be covered is clean and dry before application. Verify that sufficient heat was applied to achieve full shrinkage and a complete seal.
