4:1 Adhesive Lined (Dual Wall) Heat Shrink - BLACK - 12mm

(0 review)

Sold by the Meter!

Dual wall, high-quality heat shrink tubing that shrinks up to 4 times it's expanded size! It's also lined with a quality adhesive so the connection will be watertight.  This is perfect if you are splicing wires in a marine or wet environment.

We always try and send your order as one continuous roll, per size, unless you request differently or if you order over 80 ft.  In that case, we will send in the least amount of rolls possible.
