No-Hub Couplings
Not to be confused with Flexible Rubber Fittings, these couplings connect threaded pipes to each other and come equipped with an exterior tightening shield. The No-Hub Coupling was considered a breakthrough in plumbing, because it was the first type of fitting that connected two pipes without using melting lead. They continue to be important in most plumbing systems to this day. Nations WareHouse has all of the necessary No-Hub Couplings for your residential or small commercial plumbing or heating system.
