The Fernco 1056-22 flexible coupling is engineered with a larger tolerance than standard no-hub couplings — up to 1/2" — making it ideal for connecting different types and sizes of pipe and tubing with ease. Its flexible design accommodates cast iron, plastic, copper, steel, and lead pipe in virtually any combination.
These couplings are a reliable choice for repair, replacement, and new plumbing installations where rigid alignment is difficult or pipe materials vary. This listing includes a lot of 4 couplings, providing excellent value for contractors and maintenance professionals.
