Questions about this product

How do I choose the correct size of heat shrink tubing for my cables?
With a 4:1 shrink ratio, this tubing fits over large connectors and shrinks tightly onto the wire. Pick a size where your wire bundle is slightly larger than the recovered diameter but smaller than the expanded diameter. Keep in mind the tubing will shrink up to 10% in length during heating.
What temperature do I need to reach to get this tubing to shrink?
You need to heat the tubing to at least 70°C to 80°C to start the shrinking process. For a complete recovery and to melt the internal adhesive liner, ensure your heat source reaches 120°C. Move your heat gun constantly to prevent burning the outer polyolefin wall.
Can I use this heat shrink tubing for underwater or marine wiring?
Yes, the inner thermoplastic adhesive melts during heating to form a watertight, moisture-proof seal. The outer polyolefin wall resists common automotive and marine fluids, making it ideal for wet environments. It performs reliably in temperatures ranging from -55°C to +125°C.
