Fernco 1056-88 8in Flexible Pvc Compression Coupling

Product Description

The FERNCO 1056-88 8" is a flexible PVC compression coupling designed to create leak-proof connections between pipes in drainage, waste, and vent systems. It accommodates pipe-to-pipe joins on virtually any pipe material, including clay, cast iron, plastic, and concrete. Licensed plumbers and drainage contractors rely on this coupling for both new construction and repair work where rigid couplings are impractical. The coupling is clearly marked with the part number, size, and compatible pipe materials for quick field identification, reducing installation errors on the job site.

This coupling is suited for residential and light commercial plumbing applications, primarily in below-grade or above-grade drain, waste, and vent (DWV) lines. It is commonly installed when connecting dissimilar pipe materials or when making repairs to existing drainage runs without full section replacement. The flexible PVC shear ring design absorbs minor misalignment and deflection, making it practical in tight or shifted installations.

Key Features

• Flexible PVC construction accommodates minor pipe misalignment and deflection
• Compression coupling design creates a leak-proof seal on virtually any pipe material
• Clearly marked with part number, size, and compatible pipe material for easy field identification
• Suitable for clay, cast iron, plastic, concrete, and other common pipe materials
• 8 inch x 8 inch nominal size for standard large-diameter DWV connections

Compatibility

Designed as an OEM-style flexible compression coupling for 8 inch nominal diameter pipes across a range of pipe materials commonly found in residential and commercial DWV systems.

Installation Notes

Installation is performed by licensed plumbers in accordance with applicable plumbing codes, including the IPC. Shut off flow and relieve any system pressure before fitting the coupling. Ensure pipe ends are clean, deburred, and free of debris before seating the coupling. Do not overtighten stainless steel clamp bands beyond hand-snug plus the manufacturer-specified turns; consult torque markings on the coupling body.
