Fernco Inc P1056-33 Flexible Pipe Coupling 3x3 in

Product Description

The FERNCO INC P1056-33 is a flexible pipe coupling designed to join 3-inch pipe to 3-inch pipe in drain, waste, and vent (DWV) piping systems. It uses two stainless steel clamps to compress a flexible sleeve over the pipe ends, creating a secure, leak-resistant joint without solvent welding or threading. Licensed plumbers and pipefitters install this coupling during repairs, replacements, or new rough-in work where a rigid joint is impractical or where pipe materials differ at the connection point.

This coupling is suited for residential and light commercial plumbing applications where the run transitions between dissimilar materials or where an existing joint needs repair. It connects cast iron pipe to cast iron pipe or plastic pipe to plastic pipe within the same 3-inch nominal size. Typical install scenarios include basement drain repairs, stack repairs, and horizontal branch tie-ins where access is limited and a no-hub style coupling speeds up the work.

Key Features

• Connects cast iron to cast iron or plastic to plastic at 3 inches x 3 inches
• Two stainless steel clamps included for corrosion resistance and secure compression
• Flexible sleeve design accommodates minor misalignment and pipe movement
• No solvent cement or threading required for installation
• Sold individually as a single unit

Compatibility

Designed for 3-inch nominal cast iron or plastic DWV pipe. Connects cast iron to cast iron or plastic to plastic. Verify pipe outside diameter before installation to confirm sleeve fit.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off flow and relieve any system pressure before cutting out the failed section or fitting. Slide the clamps onto the pipe ends before seating the flexible sleeve, then torque the clamp fasteners evenly using a nut driver or torque screwdriver per the coupling manufacturer guidelines printed on the packaging. Inspect the sleeve for cuts or deformation before use and never install a damaged coupling.
