Fernco 1056-66RC Rc Coupling 6 Inch

Product Description

The FERNCO 1056-66RC is a 6-inch RC (Rigid Coupling) designed to join and align pipe sections in underground and buried piping systems. Built with a stainless steel construction, this coupling is engineered to resist heavy earth loads and shear forces that commonly affect buried infrastructure. It provides improved pipe alignment during installation, reducing stress on the joint over time. Licensed plumbers and utility contractors use this coupling in gravity-drain, sewer, and stormwater applications where ground movement and soil pressure demand a durable, load-resistant connection.

This coupling is suited for residential and commercial underground drain and sewer installations where 6-inch pipe connections require structural integrity under load. Its rigid design makes it appropriate for applications subject to soil settlement, compaction loads, or lateral shear from ground shift. It is installed where standard flexible couplings may not provide adequate resistance to axial or shear displacement.

Key Features

• Stainless steel construction for corrosion resistance in buried and wet environments
• Designed to resist heavy earth loads and shear forces on underground pipe joints
• Provides improved pipe alignment to reduce joint stress over service life
• RC (Rigid Coupling) style for applications requiring a structurally stable connection
• 6-inch pipe size suitable for large-diameter drain and sewer lines

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 6-inch diameter pipe in underground drain, waste, and sewer piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off flow and isolate the line before beginning any coupling work on active sewer or drain systems. Ensure pipe ends are clean, cut square, and free of burrs before seating the coupling. Do not overtighten fasteners beyond the manufacturer-specified torque range as noted in the product installation sheet.
