Frequently Asked Questions
What is the difference between Damp-Shrink 3:1 tubing and standard heat shrink?
Damp-Shrink tubing features adhesive-lined dual wall construction that creates a waterproof seal, making it superior to standard single-wall tubing for moisture-prone environments. The adhesive activates when heated, bonding to the cable and creating a permanent, contaminant-resistant barrier.
How do you properly heat and shrink Damp-Shrink tubing?
Apply heat evenly using a heat gun or shrink tool, maintaining consistent temperature to activate the adhesive and allow the tubing to shrink uniformly to one-third its original diameter. Proper heating ensures maximum waterproof protection and mechanical strength.
What size cables does 1.00" ID Damp-Shrink tubing fit?
The 1.00" inner diameter accommodates larger wire bundles and cable assemblies. With a 3:1 shrink ratio, it shrinks down to approximately 0.33", making it suitable for cables ranging from small multi-strand bundles to larger diameter connectors and splice points.
Is Damp-Shrink tubing suitable for marine and outdoor applications?
Yes, the adhesive-lined dual wall construction provides exceptional moisture and salt spray resistance, making Damp-Shrink tubing ideal for marine, coastal, and outdoor electrical installations where waterproof protection is critical.
