Fernco Inc P1006-44 Flexible Pipe Coupling 4 Inches

Product Description

The FERNCO INC P1006-44 is a flexible pipe coupling designed to join 4-inch clay pipe to dissimilar pipe materials including concrete, plastic, and cast iron. The coupling uses a rubber sleeve body secured by two stainless steel clamps, allowing it to absorb minor misalignment and pipe movement without compromising the seal. It is sized for 4-inch inside diameter connections on both ends. Licensed plumbers and sewer service technicians install this coupling in drain, waste, and vent systems where pipe material transitions occur at joints or repair sections.

This coupling is suited for residential and commercial plumbing applications involving underground sewer lines, storm drain repairs, and DWV piping transitions. It is commonly installed when replacing a damaged section of clay sewer pipe that ties into a concrete, cast iron, or PVC run. The flexible design accommodates slight angular and axial variation at the joint, making it practical for field repairs where pipe ends may not be perfectly aligned.

Key Features

• Connects 4-inch clay pipe to concrete, plastic, or cast iron pipe in a single coupling
• Two stainless steel clamps provide corrosion-resistant clamping force on both ends
• Flexible rubber sleeve body accommodates minor pipe misalignment and movement
• No special tools required beyond a standard torque screwdriver or nut driver
• Sold in packages of 20 units per carton

Compatibility

Designed for 4-inch clay pipe transitions to concrete, plastic, or cast iron pipe. Suitable for use in DWV and sewer drain systems where dissimilar pipe materials meet at a repair or transition joint.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Before installing, shut off any upstream flow and verify pipe ends are clean, debris-free, and cut square. Slide the coupling sleeve over one pipe end, seat the mating pipe, then tighten both stainless steel clamps evenly to the manufacturer-specified torque using a nut driver or torque screwdriver. Do not overtighten the clamps, as this can distort the rubber sleeve and compromise the seal.
