Choosing the right Sealey Heat Shrink Tubing

Use the points below as a practical starting point, then check the individual product page for the full technical information before ordering.

  • Choose tubing with a starting diameter large enough to pass over the connection.
  • Check the shrink ratio and recovered diameter to ensure a secure finished fit.
  • Use controlled, even heat and avoid overheating nearby wiring or components.
  • Select adhesive-lined or additional sealing protection where moisture resistance is required.
