Fernco fernco-hd22 Heavy Duty No Hub Coupling 2 Inches

Product Description

The FERNCO fernco-hd22 is a heavy-duty no-hub coupling designed to join no-hub cast iron pipe in drain, waste, and vent systems. It features a patented shield design that maximizes pressure transfer from the clamps to the gasket and pipe surface. The 3/8-inch hex-head screw delivers 80 inch-pounds of installation torque to the band and shield assembly, with an ultimate torque rating exceeding 100 inch-pounds. The coupling is built with heavier-gauge stainless steel compared to standard no-hub couplings. The distinctive green shield provides quick visual identification for field inspectors and installers working on rough-in and repair applications.

This coupling is used in residential and commercial plumbing systems where no-hub cast iron pipe is specified. It is engineered as a direct replacement for hub-and-spigot cast iron connections, offering a more efficient and code-compliant joining method. Licensed plumbers and pipefitters install this coupling during new construction, retrofit, and repair work on drain, waste, and vent lines. Its compliance with multiple industry standards makes it suitable for projects subject to municipal inspection in a wide range of jurisdictions, including Massachusetts and New York City.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code. Shut off water supply and relieve system pressure before beginning any pipe coupling work. Use a torque-controlled driver or torque wrench to seat the hex-head clamp screws to the specified installation torque. Do not overtighten beyond the rated torque, as this can damage the gasket and compromise the seal.
