Fernco fernco-nh22 No Hub Coupling 2 Inch

Product Description

The FERNCO fernco-nh22 is a 2-inch no-hub coupling designed to join no-hub cast iron pipe sections without the need for traditional hub-and-spigot connections. The coupling uses a patented shield design that maximizes pressure transfer from the clamps to the neoprene gasket and pipe surface, creating a reliable, leak-resistant joint. It replaces the less-efficient hub-and-spigot method and is suitable for drain, waste, and vent applications where cast iron pipe is specified. Licensed plumbers and pipefitters are the typical installers for this type of fitting in both new construction and retrofit work.

The fernco-nh22 is used in residential and commercial plumbing systems wherever no-hub cast iron pipe requires a mechanical coupling connection. Common applications include drain, waste, and vent stacks, horizontal runs, and transitions within cast iron piping systems. Its patented shield distributes clamping force evenly around the gasket, making it appropriate for overhead, in-wall, and below-grade installations where a secure, pressure-balanced joint is required.

Key Features

• Patented shield design maximizes pressure transfer from clamps to gasket and pipe
• Designed for 2-inch no-hub cast iron pipe connections
• Replaces less-efficient hub-and-spigot joining methods
• Suitable for drain, waste, and vent piping applications

Compatibility

Designed as an OEM-style replacement coupling for 2-inch no-hub cast iron pipe systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Turn off water supply and ensure the pipe section is depressurized and drained before beginning work. Use a no-hub torque wrench calibrated to the coupling manufacturer specifications to tighten the band clamps evenly. Inspect the neoprene gasket for proper seating before final torque is applied.
