Common Concerns Answered
Is the shrinking temperature difficult to achieve?
While the 257°F (125°C) shrink temperature is higher than some basic heat guns offer, a quality heat gun or a propane torch specifically designed for heat shrink applications will easily reach the required temperature, ensuring a proper, robust seal for your marine wiring.
Are these sizes readily available?
Ancor Adhesive Lined Heat Shrink Tubing is a staple for marine electrical work, with common sizes like 3/4" available in convenient 3-packs to meet the demands of most repair and installation projects.
Is the cost higher than standard heat shrink?
The investment in Ancor's adhesive-lined tubing is justified by its superior, long-lasting protection against harsh marine elements, providing an impervious seal and strain relief that non-adhesive options cannot match, ultimately saving on future repairs.
