Liquid Tight Break-Thru Plugs come in six sizes in the standard black color. These co-molded nylon and elastomer parts provide liquid tight closure when used as a plug. When pierced, Liquid Tight Break-Thru Plugs function as a liquid tight bushing that converts raw edged holes to smooth, neat, insulated holes. They mechanically protect electrical and telecommunications cables, tubing, hoses, ropes and utility lines.
