Fernco Inc P3000-33 Shielded Specialty Coupling 3 Inch

Product Description

The FERNCO INC P3000-33 is a shielded specialty coupling designed to connect 3-inch cast iron pipe to 3-inch plastic, steel, or extra heavy cast iron pipe. The stainless steel shield provides added strength and restraint at the joint, making it suitable for demanding drain, waste, and vent applications. Licensed plumbers and pipefitters install this coupling when transitioning between dissimilar pipe materials during new construction or repair work. The flexible elastomeric sleeve conforms to minor pipe irregularities, creating a leak-resistant mechanical joint without solvent cement or open flame.

This coupling is used in residential and light commercial plumbing systems where a transition between cast iron and plastic or steel pipe is required. Typical applications include DWV system repairs, stack replacements, and service lateral connections where existing cast iron pipe meets newer plastic or steel piping. The 3-inch size fits standard 3-inch nominal pipe used in drain and vent lines throughout residential and commercial construction.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off water supply and clear the line of pressure or flow before beginning work.
