Questions about this product
- What size wires will this heat shrink kit actually fit?
- This assortment covers pre-shrink diameters from 4mm to 52mm. Because of the 4:1 shrink ratio, the tubes shrink down to between 1mm and 13mm. This wide range lets you seal thick cables and thin wires with fewer tube sizes.
- Can I use this heat shrink tubing in wet or outdoor marine environments?
- Yes, this tubing is highly water-resistant. The inner adhesive lining melts at 90°C and flows to create a waterproof barrier with just 0.1% water absorption. It also withstands extreme temperatures ranging from -45°C to 125°C.
- What temperature do I need to melt the adhesive and shrink the tubing?
- The tubing starts to shrink at 70°C but requires 125°C for a full recovery. As you heat it, the inner adhesive melts at 90°C to seal the connection. Use a standard heat gun to safely reach these target temperatures.
