Too large and the tube won’t grip the cable. Wrong material and it fails at operating temperature. Non-adhesive where sealing is required, and moisture corrodes the connector within months.<\/span><\/span><\/p>\n

How to choose Heat Shrink Tube?This guide gives you a clear, step-by-step process to specify the correct heat shrink tube for any application \u2014 from basic wire insulation to aerospace-grade mil-spec harnesses.<\/span><\/p>\n

Step 1 \u2014 Determine the Required Shrink Ratio<\/span><\/h2>\n

The shrink ratio is the ratio of the tube’s supplied (expanded) inner diameter to its recovered (shrunk) inner diameter.<\/span><\/p>\n\n\n\n\n\n\n\n\n
