Common Concerns Answered
Will the adhesive bond properly?
For optimal adhesive bonding, ensure the wire surface is clean, dry, and free from oils or contaminants prior to heating. Proper surface preparation is key to achieving a truly impervious seal.
Is it difficult to get a full shrink?
Achieving the full shrink ratio requires consistent, direct heat application across the entire length of the tubing. Using a dedicated heat gun on a medium to high setting, moving it continuously, will ensure even shrinkage and proper adhesive activation.
Is this tubing a good value compared to standard heat shrink?
While the initial cost may be higher than non-adhesive tubing, the Ancor ALT's adhesive lining provides a superior, long-lasting seal that prevents corrosion and electrical failure in demanding marine environments. This significantly reduces long-term repair costs and enhances safety.
Frequently Asked Questions
