Fernco Inc P1002-44 Flexible Pipe Coupling 4 Inches

Product Description

The FERNCO INC P1002-44 is a flexible coupling designed to join 4-inch clay pipe to plastic or cast iron pipe in drainage and sewer applications. The coupling uses a flexible elastomeric sleeve secured by two stainless steel clamps, creating a leak-resistant connection without the need for special tools or adhesives. It accommodates minor misalignment and out-of-round pipe ends common in repair and retrofit work. Licensed plumbers and sewer contractors install this fitting during drain line repairs, lateral replacements, and system upgrades where dissimilar pipe materials must be joined reliably.

This coupling is used in residential and light commercial drainage systems where existing clay sewer laterals connect to newer plastic pipe sections or cast iron drain lines. It is well suited for repair scenarios where sections of clay pipe have cracked or deteriorated and a transition to PVC or ABS is required. The flexible design accommodates the slight dimensional differences that exist between clay, plastic, and cast iron pipe of the same nominal size, making it a practical choice for field repair work.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Before beginning work, shut off any upstream flow and verify the pipe ends are clean, free of sharp burrs, and properly aligned. Slide the coupling sleeve over one pipe end, insert the mating pipe, and tighten the stainless steel clamps evenly to the manufacturer torque specification printed on the product packaging. Do not overtighten clamps, as this can distort the sleeve and compromise the seal.
