For over thirty years, Electro-Prep has been “Committed to Quality Connections”.

Whether it’s cutting and stripping single, discreet wires, 4/0 to 32-gauge, building a complex harness with hundreds of components, or seamlessly delivering dozens of electro mechanical assemblies/box builds per day, rest assured they will be of the highest quality and produced by seasoned professionals.

All of our products are built to ISO 9001:2015, IPC-620 and J-STD soldering standards. We employ state-of-the-art equipment, including Schleuniger computer-controlled cut and strip machines, to bring you the highest quality products possible.
