Product Description
The FERNCO hd-150 is a heavy duty no hub coupling designed to connect no-hub cast iron pipe in drain, waste, and vent (DWV) applications. The patented shield design maximizes pressure transfer from the clamps to the gasket and pipe, creating a secure, leak-resistant joint. A 3/8-inch hex-head screw applies 80 inch-pounds of installation torque to the band and shield assembly, with an ultimate torque rating exceeding 100 inch-pounds. The heavier-gauge stainless steel construction meets the demands of commercial and residential plumbing systems. Licensed plumbers and journeymen install this coupling as a direct replacement for traditional hub and spigot connections.
The hd-150 is sized for 1-1/2-inch no-hub cast iron pipe and is used in residential and commercial DWV systems where no-hub cast iron is the pipe material of choice. The distinctive green shield allows inspectors and installers to quickly identify Heavy Duty HD couplings on the job, simplifying inspection on multi-trade projects. Typical installations include above-ground drain and vent stacks, horizontal waste runs, and fixture drain connections where code requires or specifies no-hub cast iron.

Designed for use with 1-1/2-inch no-hub cast iron pipe in DWV applications, replacing hub and spigot connections where no-hub cast iron is specified.
Installation Notes
Installation is performed by a licensed plumber in accordance with applicable plumbing codes, including the IPC and local amendments. Power down or isolate any related systems and drain the line before cutting into an existing stack or run. Use a torque wrench or calibrated nut driver to achieve proper installation torque on the hex-head screw. Do not over-torque beyond the rated value, as this can damage the gasket or shield assembly.
