Fernco hd-22 Heavy Duty No-hub Pipe Coupling 2 Inch

Product Description

The FERNCO hd-22 is a heavy duty no-hub pipe coupling designed to join no-hub cast iron pipe in drain, waste, and vent (DWV) systems. Built to the HD Series specification, it features a patented shield design that maximizes pressure transfer from the clamps to the gasket and pipe, producing a tight, leak-resistant connection. The coupling body and shield are constructed from stainless steel for corrosion resistance in wet, below-grade, and exposed piping environments. Licensed plumbers and pipefitters install this fitting in both new construction and repair applications where a reliable mechanical joint is required.

The hd-22 is sized for 2 inch nominal no-hub cast iron pipe and is suited for residential and light commercial DWV installations. Its no-hub design eliminates the need for traditional hub-and-spigot jointing methods, reducing installation time and the need for specialized lead-and-oakum tooling. It is manufactured domestically and meets multiple industry standards, making it an accepted fitting in jurisdictions that require code-listed drainage products.

Key Features

• Patented shield design transfers clamp pressure evenly to gasket and pipe for a secure seal
• Stainless steel construction resists corrosion in wet and buried installations
• No-hub design replaces less-efficient hub-and-spigot connections
• Meets ASTM C564/C1540, CISPI 310, and IAPMO File No. 3198 standards
• Domestically manufactured in the United States

Compatibility

Designed as an OEM-style no-hub coupling for 2 inch nominal no-hub cast iron pipe in residential and commercial DWV piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off flow and depressurize or drain the line before removing any existing fittings. Ensure pipe ends are clean, square-cut, and free of burrs before seating the gasket and positioning the shield. Torque clamp bands evenly and in sequence per the fitting manufacturer instructions to achieve proper gasket compression.
