Homewerks Worldwide Llc 522-03-3 No Hub Coupling 3 Inches

Product Description

The HOMEWERKS WORLDWIDE LLC 522-03-3 is a 3-inch no hub coupling designed to join cast iron pipe and fittings in no-hub drain, waste, and vent systems. Each unit ships fully assembled, consisting of a molded neoprene sealing sleeve encased by stainless steel corrugated shield clamps. The neoprene sleeve compresses against the pipe ends to create a leak-resistant seal, while the stainless steel shield and clamps provide structural support and corrosion resistance. Licensed plumbers and pipefitters install this coupling in new construction and retrofit DWV applications where soldered or banded joints are required.

This coupling is suited for residential and light commercial no-hub cast iron piping systems, including drain, waste, and vent assemblies. It is commonly installed in above-grade and below-slab applications where cast iron pipe sections need to be joined without a hub connection. The assembled design reduces field preparation time, making it a practical choice for production plumbing work. Units are packaged 25 per carton.

Key Features

• Fully assembled at the factory — neoprene sleeve and stainless steel shield clamps shipped as one unit
• Molded neoprene sealing sleeve provides a compressed, leak-resistant pipe joint
• Stainless steel corrugated shield clamps deliver corrosion resistance and mechanical strength

Compatibility

Designed as an OEM-style replacement and standard fitment coupling for 3-inch no-hub cast iron pipe and fittings in residential and commercial DWV systems.

Installation Notes

Installation is performed by licensed plumbers in accordance with applicable plumbing codes such as the IPC or local adopted equivalents. Before servicing an existing system, shut off water supply and verify the line is depressurized and drained. Use an approved no-hub torque wrench or band clamp driver to tighten shield clamps to the manufacturer-specified range — do not overtighten, as this can distort the neoprene sleeve and compromise the seal. Inspect pipe ends for burrs or damage before seating the coupling.
