Choose a size where the pre-shrink inner diameter is at least 10–20% larger than your component. With a 4:1 ratio, the tubing will shrink down to roughly one-quarter of its original diameter — so a φ8mm (≈5\/16\") tube recovers to approximately 2mm (≈5\/64\"), giving you a wide working range per size.

This is significantly more than standard 2:1 tubing, making it suitable for irregular shapes, stepped connectors, and bundled cables where a tight, conforming seal is needed. It also means one size can cover a broader range of substrates.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this heat shrink tubing waterproof or moisture-resistant?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eTransparent 4:1 heat shrink tubing is generally dual-wall construction with an inner adhesive lining that melts and flows during shrinking to create a moisture-resistant seal around the substrate.

It typically offers UV resistance, a wide operating temperature range (commonly −55°C to +125°C \/ −67°F to +257°F), and resistance to fuels, oils, and mild chemicals.
