Common Concerns Answered
Are there different length options available?
This specific pack contains five 12" sections, ideal for many applications. While we offer various lengths, this pack is optimized for common marine wiring needs. For very small or large, specialized jobs, you might consider sourcing specific lengths if the 12" sections are not ideal.
What if I don't get a good seal?
Achieving a perfect seal relies on sufficient and even heat application with a heat gun or torch. Ensure the entire tubing circumference is exposed to heat until the adhesive flows completely, creating an impenetrable barrier.
Is this tubing worth the investment compared to cheaper options?
While the initial cost may exceed generic tubing, Ancor's marine-grade quality, specialized adhesive lining for a waterproof seal, and UL 224 certification deliver superior long-term performance and reliability in corrosive saltwater environments, justifying the investment.
Frequently Asked Questions
What is the shrink ratio of Ancor Adhesive Lined Heat Shrink Tubing?
The shrink ratio of this Ancor Adhesive Lined Heat Shrink Tubing is 3:1, meaning it will shrink to one-third of its original diameter.
What is the operating temperature range for this heat shrink tubing?
This heat shrink tubing is designed to operate reliably in a wide temperature range of -40°C to 110°C (-40°F to 230°F).
What wire gauge range is compatible with this 3/8" heat shrink tubing?
This 3/8" diameter Ancor heat shrink tubing is compatible with wire gauges ranging from 12 AWG to 8 AWG.
Is this heat shrink tubing resistant to saltwater and oil?
Yes, the heat-activated adhesive lining creates an impervious seal that is resistant to saltwater, oil, acids, and sunlight, crucial for marine applications.
What is the purpose of the adhesive lining in this heat shrink tubing?
The adhesive lining serves two primary purposes: to create a completely waterproof and environmental seal around the electrical connection, and to provide enhanced strain relief for the wire termination.
