4:1 Marine Grade Heat Shrink Tubing - Adhesive Glue Lined Waterproof Wire Wrap

Keep your electrical connections safe from moisture with this 4:1 marine grade heat shrink tubing.

It's a dual-wall polyolefin tube with an inner adhesive glue liner that melts and seals when heated, creating a waterproof, corrosion-proof barrier.

Choose from 3, 8, or 15 foot lengths, all black.

Shrink ratio is 4:1 (shrinks to 1/4 of original diameter), and full shrinkage happens at 120°C (248°F).

Operating range is -50°C to 125°C (-58°F to 257°F).

Perfect for automotive, marine, or any outdoor wiring.

Brand new, unbranded but quality material.

Stop using electrical tape—use this for a permanent seal.
