1/4 Inch vinyl insulated push on terminals are tinned copper push on terminals with a vinyl insulating cover surrounding the crimp barrel to help protect against short circuits. The insulation is flared to make inserting your wire easier and is color coded depending on the wire size: 22-18 awg - red, 16-14 awg - blue, 12-10 awg - yellow. Our vinyl push on terminals have excellent retention strength and are available in both male and female versions. They are rated for use up to 600 volts. Vinyl push on terminals can be crimped using any standard insulated terminal crimping tool.
