1/0 Wire Ferrules With Heat Shrink


Insure reliable electrical connections and prevent fraying and breaking of wire strands when terminating conductors in screw clamp terminal blocks.


Uninsulated ferrules prevent wire strands from fraying and breaking and are extremely cost effective. Their shorter lengths and uninsulated bodies offer advantages when making terminations in narrow widths. To ensure efficient ferrule crimping, always select the smallest ferrule diameter that fits the wire and use only professional crimping tools.

Fit perfectly

Was able to salvage already in use wire ends without having to make another clean cut. I’m always changing my setup around and having to trim my wires all the time to reinsert them. Specifically my wires from front battery to rear secondary. Worth buying the 25pk. Highly recommended.

Great quality

It's hard to find 0 AWG ferrules that are actually the right size, these were spot on. And the heat shrink was really good quality, thicker than most.

1/0 ferrules

Amazing product. Fit was tight and added a slight more professionally finished look overall. Will be ordering more products.
