The FERNCO 1056-22RC is a shielded strong-back pipe coupling designed for sewer, drain, waste, and vent piping applications where a secure, gas-tight connection is required. The body is made from elastomeric polyvinyl chloride wrapped in 300 series stainless steel, giving it resistance to heavy earth loads and shear forces while maintaining the flexibility to absorb ground movement and vibration. Rated for both above-ground and below-ground installations, the 1056-22RC accepts pipe outside diameters between 2.15 and 2.5 inches on both ends, with an internal diameter of 2.4 inches. Licensed plumbers and pipefitters are the primary installers on residential, commercial, and municipal drainage work.
The 1056-22RC is suited for connecting cast iron, plastic, or steel pipe to cast iron, plastic, or steel pipe in a wide range of project types. Typical applications include municipal infrastructure, new construction rough-in, retrofit repairs, and temporary connections on active job sites. The coupling works on both permanent and temporary installations, making it a practical choice when a quick, reliable connection is needed without solvent cement or primer. Its flexibility allows it to accommodate minor pipe misalignment, which is common in repair situations where existing pipe ends may not be perfectly straight.
