Pasco HD-44 No Hub Coupling 4 Inches Heavy Duty

Product Description

The PASCO HD-44 is a heavy-duty no-hub coupling designed to join cast iron, plastic, or other no-hub pipe systems without threaded or hubbed fittings. It uses a stainless steel shield and clamp band system to create a secure, leak-resistant connection. Weighing 0.945 pounds, this coupling fits 4-inch diameter pipe and is built for demanding drain, waste, and vent (DWV) applications. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit work where a reliable, tool-torqued band connection is required.

The HD-44 is suited for residential and light commercial DWV systems where 4-inch no-hub pipe connections are required. Common install scenarios include main drain lines, building sewers, and vertical stack connections. Its heavy-duty construction makes it appropriate for applications where a standard-duty coupling may not provide sufficient clamping strength or durability.

Key Features

• Heavy-duty construction for demanding DWV applications
• No-hub design eliminates need for threaded or hubbed fittings
• Fits 4-inch pipe diameter
• Stainless steel shield and clamp band provide secure, leak-resistant seal
• Lightweight at 0.945 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch no-hub drain, waste, and vent pipe systems.

Installation Notes

Installation is performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off water supply and ensure the pipe section is depressurized before beginning work. Use a calibrated torque wrench to tighten clamp bands to the manufacturer-specified torque for no-hub couplings as required by code. Inspect the neoprene sleeve for proper seating against both pipe ends before final tightening.
