Questions about this product
- How do I choose the right size, and how much will this tubing shrink?
- This tubing has a 3:1 shrink ratio, meaning it shrinks to one-third of its original size. We offer pre-shrink diameters from 3.2 mm up to 25.4 mm, which recover down to 1.1 mm and 8.5 mm respectively. Just ensure your cable diameter is slightly smaller than the pre-shrink size and larger than the post-shrink size.
- What tool do I need to shrink this tubing, and what is the required temperature?
- You will need a heat gun or a compatible heat source to shrink the polyolefin material. The tubing begins to shrink at 70°C, but it requires a full recovery temperature of 110°C to shrink completely. As you apply heat, the inner thermoplastic adhesive layer melts to seal your connection.
- Can I use this heat shrink outdoors or in wet environments?
- Yes, you can confidently use this tubing outdoors and in wet areas. The inner adhesive lining melts to form a watertight seal with a very low water absorption rate of 0.1%. It also resists common chemicals, handles temperatures from -45°C to 125°C, and offers good UV resistance.
