Questions about this product
- How much do these tubes shrink, and what wire sizes do they fit?
- These tubes have a high 4:1 shrink ratio, meaning they shrink to a quarter of their original size. This extreme shrinkage lets them slide easily over bulky connectors and still seal tightly around thin wires. The kit includes assorted pre-cut lengths with starting inner diameters ranging from 3.2 mm up to 25.4 mm.
- What tool should I use to shrink this tubing, and what temperature is required?
- We recommend using a heat gun for even heat distribution. The tubing starts to shrink at 70°C and achieves full recovery at 125°C. As you heat the sleeve, the inner adhesive melts at 90°C to squeeze out air and seal the connection.
- Can I use this heat shrink tubing for outdoor, marine, or automotive wiring?
- Yes, this polyolefin tubing is designed for harsh environments. It withstands extreme temperatures ranging from -55°C up to 125°C. The melted adhesive lining blocks out moisture, salt water, and corrosive fluids to prevent wire rot.
