Fernco Inc P1001-44 Flexible Pipe Coupling 4 Inch

Product Description

The FERNCO INC P1001-44 is a flexible pipe coupling designed to join 4-inch clay pipe sections in underground drain and sewer systems. It uses a elastomeric sleeve that compresses around the pipe ends, creating a watertight seal without requiring solvent cement or special tools. Two stainless steel clamps are included and tighten over the sleeve to lock the connection in place and resist pullout. This coupling is installed by licensed plumbers and sewer contractors working on gravity-flow drainage lines, storm sewer laterals, and sanitary sewer repairs.

This coupling is suited for residential and light commercial sewer lateral repairs where existing clay pipe must be rejoined or transitioned. It is commonly used in trench repair situations where a section of clay pipe has been removed or damaged. The flexible sleeve accommodates minor misalignment between pipe ends, which is useful in settled or shifted pipe runs. Installation does not require flame, adhesive, or threading equipment, making it practical for confined trench conditions.

Key Features

• Fits 4-inch clay pipe on both ends for a same-size inline connection
• Flexible elastomeric sleeve provides a watertight mechanical seal
• Two stainless steel clamps included for corrosion resistance and secure clamping
• Accommodates minor pipe misalignment common in older clay sewer runs
• No solvent, flame, or threading required for installation

Compatibility

Designed as an OEM-style flexible coupling for 4-inch outside-diameter clay pipe used in residential and commercial gravity-drain and sewer lateral applications.

Installation Notes

Installation is performed by a licensed plumber or sewer contractor in accordance with local plumbing codes and IPC guidelines. Shut off flow to the line and ensure the trench is dewatered before beginning work. Clean both pipe ends of debris, root intrusion, and soil before sliding the coupling sleeve into position. Tighten the stainless steel clamps evenly to the torque range specified on the coupling packaging to ensure a uniform seal.
