The FERNCO 1056-150RC is a shielded strong-back pipe coupling designed to join cast iron, plastic, or steel pipe to cast iron, plastic, or steel pipe in drain, waste, and vent systems. The body is constructed from elastomeric polyvinyl chloride wrapped in 300 series stainless steel, giving it resistance to heavy earth loads, shear forces, and sewer gases. This coupling has an internal diameter of 1.9 inches and accepts pipe outside diameters between 1.65 and 2 inches on both ends. Licensed plumbers and pipefitters install this fitting in both below-grade and above-grade applications, including permanent and temporary installations on residential, commercial, and municipal projects.
This coupling is suited for sewer and drain, waste, and vent piping where a no-hub or transition connection is required. Its flexible elastomeric body accommodates minor pipe misalignment and absorbs ground movement or vibration without transferring stress to the adjoining pipe. Typical applications include connecting dissimilar pipe materials during repair or new construction, tying into existing cast iron stacks, and making transitions on municipal infrastructure and construction job sites. Both above-ground and below-ground service is rated for this fitting.

Installation Notes
Installation is performed by a licensed plumber in accordance with the International Plumbing Code or applicable local code. Shut off flow and relieve any system pressure before cutting into an existing line. No primer, solvent cement, or sealant is required - secure the clamps using a screwdriver, nut driver, or torque wrench. Confirm pipe ends are clean, square, and free of burrs before seating the coupling to ensure a proper seal.
