Fernco 3001-44 Proflex Shielded Coupling 4 in Ci to Copper

Product Description

The FERNCO 3001-44 is a ProFlex neoprene compression shielded coupling designed to connect 4-inch cast iron pipe to 4-inch copper pipe in above-ground drain, waste, and vent applications. The neoprene sleeve compresses against both pipe ends to form a watertight seal, while the stainless steel shielding band and clamps resist shear forces and create a rigid, long-lasting joint. Licensed plumbers and pipefitters install this coupling where dissimilar pipe materials must be joined without soldering, threading, or hub fittings. It is manufactured in the USA.

This coupling is suited for above-ground residential and light commercial plumbing systems where a cast iron drain line transitions to copper piping. Typical install scenarios include stack connections, fixture branch tie-ins, and repair sections where a damaged pipe segment has been cut out and replaced with copper. The shielded design makes it appropriate for exposed or accessible installations where joint rigidity is required.

Compatibility

Designed for above-ground plumbing connections joining 4-inch cast iron pipe to 4-inch copper pipe in drain, waste, and vent systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code. Shut off water supply and relieve system pressure before cutting into any active drain or supply line. Pipe ends should be clean, deburred, and free of dirt or grease before the neoprene sleeve is positioned and the clamps are tightened. Do not use this coupling for below-ground or buried service unless the product is specifically rated for that application.
