NT250025 | High Temperature Wire Ferrules

Our High Temperature Wire Ferrules are made of untinned copper with a flared end for easy wire entry.

What is a wire ferrule? A wire ferrule is a tinned (or untinned) copper sleeve, which is slipped over stranded wire and then crimped. This creates a solid connection for insertion into terminal block housings or various other applications. The crimped ferrule provides a sturdy connection that limits wire fraying and increases the life of the conductor. Our ferrules are sold in packages, strips, and also in reel form.
