Fernco Inc P1051-44 Flexible Pipe Coupling 4 Inches

Product Description

The FERNCO INC P1051-44 is a 4-inch flexible pipe coupling designed to join dissimilar pipe materials in drain, waste, and vent (DWV) piping systems. It accommodates connections between asbestos cement or ductile iron pipe and cast iron or plastic pipe, making it a practical solution where material transitions occur in existing or new installations. The flexible design absorbs minor misalignment and vibration, which is a common requirement in repair and retrofit work. Licensed plumbers install this coupling in residential and light commercial applications.

This coupling is used in underground and above-grade DWV piping systems where different pipe materials meet. Typical scenarios include sewer lateral repairs, stack replacements, and drain line tie-ins where the existing pipe material differs from new piping. It is well suited for residential service upgrades and commercial drain system renovations where cast iron transitions to PVC or ABS.

Key Features

• Connects 4-inch asbestos cement or ductile iron pipe to 4-inch cast iron or plastic pipe
• Flexible construction accommodates minor pipe misalignment and movement
• Designed for DWV drain, waste, and vent piping applications
• Sold in a package quantity of 20 units per case

Compatibility

Designed for transitions between asbestos cement or ductile iron pipe and cast iron or plastic pipe at the 4-inch nominal pipe size.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC or regional equivalents. Shut off flow and confirm the pipe ends are clean, deburred, and free of dirt or grease before seating the coupling. Tighten stainless steel clamp bands evenly to the torque range specified on the coupling or manufacturer documentation. Do not overtighten, as this can deform the neoprene sleeve and compromise the seal.
