Double crimp nylon insulated push on terminals are quick connect wire terminals that come in both male and female versions for wire sizes ranging from 22 gauge to 10 gauge. Double crimp design crimps the wire and the insulation for extra pull strength and strain relief. Nylon insulating maternal won't deform from crimping and will hold up to higher temperatures than standard vinyl (PVC) insulation. The partially insulated nylon material is color coded based on the wire size. Double crimp nylon push on terminals are rated to 600 volts and temperatures up to 221°F (105°C). Quick connect push on size is 1/4 inch. These are higher performance push on terminals that are suitable for use in automotive and marine electrical systems, as well as commercial and industrial electrical applications.
