Fernco Inc P1056-66 Pipe Coupling 6x6 Inches

Product Description

The FERNCO INC P1056-66 is a flexible pipe coupling designed to join 6-inch pipe to 6-inch pipe across a wide range of materials, including cast iron, plastic, copper, steel, and lead. It provides a reliable, leak-resistant connection in drain, waste, and vent (DWV) piping systems. The coupling uses a flexible elastomeric sleeve and stainless steel clamps to create a secure mechanical joint without the need for soldering, gluing, or specialty tooling. Plumbers and pipefitters install this type of coupling when transitioning between dissimilar pipe materials or when making repairs to existing drain lines.

This coupling is suited for residential and light commercial plumbing applications where 6-inch DWV pipe is used. Common install scenarios include sewer lateral repairs, stack connections, and horizontal drain runs where a no-hub or transition joint is required. Its multi-material compatibility makes it a go-to solution when a jobsite presents mixed piping materials that must be joined in a single connection point.

Key Features

• Connects cast iron, plastic, copper, steel, and lead pipe in a single coupling
• 6-inch by 6-inch nominal pipe size for same-diameter connections
• Flexible elastomeric sleeve accommodates minor misalignment and pipe irregularities
• Stainless steel clamp band construction for corrosion resistance
• No soldering, gluing, or open flame required for installation
• Sold as a single unit (EA)

Compatibility

Designed as an OEM-style transition and repair coupling for 6-inch DWV pipe systems utilizing cast iron, plastic, copper, steel, or lead pipe materials.

Installation Notes

Installation is performed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water flow and relieve system pressure before cutting into any existing drain line. Pipe ends should be clean, deburred, and free of debris before seating the coupling sleeve. Tighten clamp bands evenly to the fitting manufacturer's general guidance and verify no leaks are present before returning the system to service.
