Our industrial plugs have single piece housings made of impact resistant polycarbonate which offers high physical strength and superior dielectric properties. Pair with our silver plated solid copper contacts that offer low resistance for superior conductivity. The contacts have a self cleaning design to resist arcing by keeping conductive surfaces clean and free of corrosion. With integral stainless steel sprints, this product maintains constant pressure on the contact to ensure a consistent, low-resistance connection. Each kit includes contacts and housing.
