Homewerks Worldwide Llc 522-03-2-112 No Hub Coupling

Product Description

The HOMEWERKS WORLDWIDE LLC 522-03-2-112 is a no hub coupling designed to join cast iron pipe and fittings in no hub drainage systems. It ships fully assembled, with stainless steel corrugated shield clamps pre-installed over a molded neoprene sealing sleeve. The coupling connects a 2-inch pipe to a 1-1/2-inch pipe, making it a reducing coupling suited for transitioning between two common drain line sizes. Licensed plumbers and drain system installers use this fitting during new construction and repair work on cast iron no hub systems.

This coupling is used in residential and commercial no hub cast iron drain, waste, and vent systems. Its reducing configuration handles the transition from a 2-inch line down to a 1-1/2-inch line, a common requirement at fixture branch connections. The assembled design reduces staging time during installation. It is appropriate for below-grade, in-wall, and exposed applications where no hub cast iron pipe is the specified system material.

Key Features

• Reducing coupling connects 2-inch pipe to 1-1/2-inch pipe in no hub systems
• Ships fully assembled — stainless steel corrugated shield clamps pre-installed over neoprene sleeve
• Molded neoprene sealing sleeve provides a flexible, watertight connection
• Stainless steel corrugated shield clamps resist corrosion in wet drain environments
• Designed for use with cast iron pipe and fittings in no hub configurations

Compatibility

Designed as an OEM-style replacement fitting for no hub cast iron drain, waste, and vent pipe systems using 2-inch to 1-1/2-inch reducing connections.

Installation Notes

Installation is performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code. Shut off flow to the affected line and ensure the pipe ends are clean, deburred, and properly aligned before seating the neoprene sleeve. Tighten the stainless steel shield clamps evenly using a torque-limiting band clamp driver or standard nut driver per the coupling manufacturer's torque specification. Do not over-tighten, as this can deform the neoprene sleeve and compromise the seal.
