Homewerks Worldwide Llc 522-03-4 No Hub Coupling 4 in

Product Description

The HOMEWERKS WORLDWIDE LLC 522-03-4 is a 4-inch no hub coupling designed to join cast iron pipe and fittings in no hub drainage systems. The assembly ships ready to install, with stainless steel corrugated shield clamps pre-assembled over a molded neoprene sealing sleeve. This configuration creates a durable, leak-resistant joint without the need for hub-style pipe ends. Licensed plumbers install this coupling in both new construction and repair applications where no hub cast iron drain, waste, and vent systems are present.

This coupling is suited for residential and light commercial plumbing systems using 4-inch no hub cast iron pipe. It is commonly installed in drain, waste, and vent configurations where a secure, band-clamped neoprene sleeve connection is required. The corrugated stainless steel shield provides added structural support around the neoprene sleeve, maintaining joint integrity under normal pipe movement and operating conditions.

Compatibility

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off water supply and ensure the pipe is fully drained before beginning work. Slide the coupling over the pipe ends, seat the neoprene sleeve fully, and torque the shield clamps evenly using a torque wrench or nut driver to the no hub coupling standard. Inspect the joint for proper sleeve seating before restoring flow.
