Mark's Color-Coded Thermoplastic Wire Nuts Extra Small Blue

Mark's color-coded wire nuts have a tight, square-wire spring that makes quick, secure connections. They resist chemical action from hydrocarbons, dilute acid, or alkaline solutions. Flame retardant properties resist heat distortion up to 105 C (221 F). Their tough, thermoplastic shell shields against environmental extremes. The color-coded high dielectric shell features a deep skirt design to prevent exposure of bare wire while providing superior flash-over protection. The skirt also has a fluted outside surface giving the installer a positive grip on the nut.
