Buying Guide

Choose the right shrink ratio

Select a 3:1 or appropriate shrink ratio to ensure secure fit across the range of cable diameters you need to cover

Prefer adhesive-lined (dual-wall) for waterproofing

Adhesive-lined, dual-wall tubing provides a bonded seal and added mechanical protection, which is important for outdoor or moisture-prone installations

Match tubing diameter to cable bundle

Measure the maximum cable bundle diameter and select a tubing size that will fully recover to a tight fit when heated

Check material compatibility

Use tubing materials rated for oil resistance and the temperatures expected in your environment to prevent degradation over time

Consider spool length for project scale

Choose longer rolls (50 ft or more) when outfitting multiple runs to reduce joins and simplify inventory management
