Fernco Fernco Mod Proflex Shielded Coupling 3 Inch Ci to Copper

Product Description

The FERNCO fernco mod ProFlex neoprene compression shielded coupling connects 3-inch cast iron pipe to 3-inch copper pipe in above-ground drain, waste, and vent applications. The coupling uses a neoprene sleeve compressed by stainless steel shielding bands to form a rigid, shear-resistant mechanical joint without soldering, threading, or hubbed fittings. This design creates a long-lasting pipe joint suited for repair or new installation work. Licensed plumbers and journeyman pipe fitters are the primary installers. The stainless steel banded construction resists corrosion in exposed above-ground conditions. Manufactured in the USA.

This coupling is designed for above-ground plumbing applications where a transition between cast iron and copper pipe is required, such as residential or light commercial drain, waste, and vent systems. It is particularly useful during repair work where a damaged section of pipe must be replaced without disturbing adjacent fittings. The shear-resistant joint construction makes it appropriate for areas subject to vibration or minor structural movement.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off water supply and relieve system pressure before cutting into any live line. Use a torque wrench or nut driver to tighten shielding band clamps evenly and to the band manufacturer guidance. Inspect the neoprene sleeve for cuts or debris before seating to ensure a leak-free connection.
