600 piece assorted nylon insulated automotive electrical connector kit. This is a quality automotive wire connector kit. All connectors are made in the USA with quality and pride. We package the terminal connector kit with all nylon insulated crimp connectors. Nylon insulation is better than vinyl insulation. Nylon insulation is resistant to higher temperatures than vinyl and nylon insulation is more flexible, allowing the insulation to flex when crimped where vinyl will crack. These are quality connectors and come with our money back guarantee. 25 pcs. - 22-18 Nylon Butt 25 pcs. - 16-14 Nylon Butt 25 pcs. - 12-10 Nylon Butt 25 pcs. - 22-18 Nylon Ring #10, 1/4, 5/16, 3/8 25 pcs. - 22-18 Nylon Spade #10 25 pcs. - 16-14 Nylon Ring #10, 1/4, 5/16, 3/8 25 pcs. - 16-14 Nylon Spade #10 25 pcs. - 12-10 Nylon Ring #10, 1/4, 5/16, 3/8 25 pcs. - 12-10 Nylon Spade #10 25 pcs. - 22-18 Nylon Quick Disconnect .250 Male & Female 25 pcs. - 16-14 Nylon Quick Disconnect .250 Male & Female 25 pcs. - 12-10 Nylon Quick Disconnect .250 Male & Female
