Fernco fernco-1056-66 Flexible Pipe Coupling 6 Inch

Product Description

The FERNCO fernco-1056-66 is a flexible pipe coupling designed to join, repair, or transition 6-inch diameter pipe sections in drain, waste, and vent (DWV) systems. The shielded coupling design uses a flexible elastomeric sleeve secured by stainless steel clamps to create a leak-resistant, pressure-rated connection. Licensed plumbers and experienced pipe installers use this type of coupling for no-hub pipe connections where rigid fittings are impractical or where vibration isolation is needed. The flexible construction allows for minor angular deflection and pipe misalignment during installation.

This coupling is suited for residential and light commercial plumbing applications, primarily in DWV piping systems. It is commonly used for underground drain repairs, sewer lateral connections, and transitions between pipe materials such as cast iron, PVC, ABS, and clay tile. The 6-inch diameter size is typical in main building drain lines and sewer service connections where high flow capacity is required.

Key Features

• Flexible elastomeric sleeve accommodates minor misalignment between pipe ends
• 6-inch nominal pipe size suits main drain and sewer service applications
• Shielded coupling design provides added structural support at the joint
• Compatible with multiple pipe materials for transitions and repairs
• Stainless steel clamp band tightening provides a secure, leak-resistant seal

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for 6-inch nominal DWV pipe systems including drain, waste, and vent applications in residential and light commercial construction.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Before installation, shut off any connected water supply and ensure the pipe section is fully drained and dry. Clean and deburr pipe ends before seating the elastomeric sleeve to ensure a proper seal. Do not overtighten clamp bands beyond manufacturer torque guidance, and inspect the sleeve for tears or deformation before placing the joint into service.
