Sealey Heat Shrink Terminals Guide
Heat-shrink terminals combine an electrical connection with added insulation and environmental protection around the crimped joint. This guide groups Sealey heat-shrink terminal products so you can compare terminal styles, cable sizes and pack options for automotive and workshop wiring repairs.
Choosing heat-shrink terminals
Use the points below as a practical starting point, then check the individual product page for the full technical information before ordering.
- Match the terminal size to the conductor cross-section and the connection type required.
- Use the correct crimping die to achieve a secure mechanical and electrical connection.
- Apply controlled heat evenly until the sleeve has recovered without overheating the cable insulation.
- For moisture-prone locations, check whether the terminal specification provides the sealing performance required.
