1Constructed of copper material for high electric conductivity. 2The surface is tin-plated, to have good oxidation resistance and corrosion resistance. 3Very easy to connect with electrical wire and strengthen its reliability and safety. 4Wire stop structure is conductive to insertion wire in right space to ensure the effect of compression. 5Non-insulated design with iron wire barrier in the center, only needs a crimping tool to make the splicing very simple, crimping ,solder and heat shrink for a grade A splice. 6These butt connectors will work well when building custom wire harnesses or making repairs to existing wiring.100 x 22-18AWG100 x 16-14AWG100 x 12-10AWG1 x Plastic BoxCondition: new Item Type: Cord terminal_x000D_Material: Copper_x000D_Color: Silver _x000D_Quantity: 300pcs_x000D_Application: Applicable for naked takeovers such as ships and automobiles 1Constructed of copper material for high electric conductivity. 2The surface is tin-plated, to have good oxidation resistance and corrosion resistance. 3Very easy to connect with electrical wire and strengthen its reliability and safety. 4Wire stop structure is conductive to insertion wire in right space to ensure the effect of compression. 5Non-insulated design with iron wire barrier in the center, only needs a crimping tool to make the splicing very simple, crimping ,solder and heat shrink for a grade A splice. 6These butt connectors will work well when building custom wire harnesses or making repairs to existing wiring.100 x 22-18AWG100 x 16-14AWG100 x 12-10AWG1 x Plastic Box
