Fernco Fernco Mod 6x6 Flexible Pipe Coupling

Product Description

The FERNCO fernco mod is a flexible pipe coupling designed to join two 6-inch diameter pipes in drain, waste, and vent (DWV) systems. The coupling uses a compressible elastomeric sleeve to create a leak-resistant connection between pipe ends, accommodating minor misalignment and absorbing vibration. Licensed plumbers and drain contractors install this type of fitting when making no-hub connections in underground, in-wall, or above-slab piping configurations. It is a standard tool-less-prep solution for connecting same-diameter pipe sections without hot work or solvent welding.

This 6-inch by 6-inch coupling is suited for residential and commercial plumbing applications where DWV piping requires repair, extension, or transition connections at matching pipe diameters. Typical install scenarios include sewer lateral repairs, stack connections, and horizontal drain runs. The flexible design allows it to bridge cast iron, PVC, ABS, clay, and other common pipe materials at the same nominal diameter, making it a practical choice for repair work on mixed-material systems.

Key Features

• Flexible elastomeric sleeve accommodates minor pipe misalignment and settles into position under compression
• 6-inch by 6-inch nominal sizing for same-diameter connections on large-diameter DWV lines
• No-hub design eliminates the need for solvent cement, lead, or oakum on repair joints
• Compatible with multiple pipe materials at the same nominal diameter including cast iron, PVC, ABS, and clay
• Stainless steel band clamps provide consistent compression around the sleeve perimeter

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for 6-inch nominal diameter DWV piping systems. No specific model or system compatibility data was provided in the product input.

Installation Notes

Installation is performed by a licensed plumber in accordance with the applicable edition of the International Plumbing Code (IPC) or local adopted plumbing code. Shut off flow and drain the line completely before cutting out the damaged section or making new connections. Pipe ends should be clean, deburred, and free of scale or debris before sliding the coupling into position. Tighten stainless steel band clamps evenly and do not over-torque beyond the fitting manufacturer guidelines printed on the packaging.
