Upon cooling, it bonds the tubing to the substrate, creating a continuous seal with no moisture entry points—unlike a single-wall tubing that only clamps mechanically. The adhesive bonds to PVC, polyethylene, rubber, and aluminum.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation temperatures\u003c\/h3\u003e\n\u003cp\u003eShrink starts around 80 °C, but full overlap requires \u003cstrong\u003e125 °C\u003c\/strong\u003e. Aim for 125 °C with a heat gun; stopping at 110 °C yields partial shrink and incomplete bonding.
