Fernco Inc P1059-33 Flexible Coupling 3 Inches

Product Description

The FERNCO INC P1059-33 is a 3-inch flexible coupling designed to connect socket-end pipe to plain-end pipe in drain, waste, and vent (DWV) plumbing systems. It uses a shear-ring clamp and elastomeric sleeve to create a leak-resistant, pressure-rated joint without solvent cementing or special tooling. The flexible design accommodates minor misalignment and slight angular deflection, making it a practical solution for repair work and new rough-in installations alike. Licensed plumbers and experienced pipefitters are the primary installers of this type of fitting.

This coupling is suited for residential and light commercial plumbing applications where a quick, reliable transition or repair joint is needed on 3-inch pipe runs. It is commonly used to reconnect drain lines after cutting out damaged sections, to tie into existing cast iron or plastic pipe, and to make socket-to-plain-end transitions where rigid fittings are impractical. The 3-inch size fits standard 3-inch pipe used in toilet drain lines, branch drains, and main stack connections.

Key Features

• 3-inch by 3-inch socket-to-pipe connection for DWV applications
• Flexible elastomeric sleeve accommodates minor pipe misalignment and vibration
• Shear-ring stainless steel clamp bands provide secure, leak-resistant compression
• No solvent cement, heat, or special tools required for installation
• Sold as individual units; package quantity of 20 per case

Compatibility

Designed as an OEM-style replacement and repair coupling for standard 3-inch DWV pipe systems including cast iron, plastic, and clay pipe configurations.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off water supply and drain the affected line completely before cutting into the pipe. Ensure pipe ends are clean, deburred, and free of dirt or grease before seating the coupling sleeve. Tighten clamp bands evenly and to the coupling manufacturer-specified procedure; refer to applicable IPC or local plumbing code requirements for inspection and acceptance criteria.
