Nibco h-78007 Air Separator 2 Inch Copper Press

Product Description

The NIBCO h-78007 is a 2-inch copper press brass air separator designed for hydronic heating and cooling systems. Air separators remove entrained air from circulating fluid, protecting pumps, reducing noise, and improving heat transfer efficiency. The h-78007 uses copper press connections for fast, solderless installation, and its brass construction offers corrosion resistance suited to closed-loop hydronic piping. Licensed plumbers and hydronic system technicians are the primary installers of this component.

The h-78007 is used in residential and light commercial hydronic systems, including hot water heating loops, chilled water circuits, and radiant floor systems. Its 2-inch port size suits main distribution piping in medium-capacity systems. It installs in-line on supply or return mains where air accumulation is most likely, typically near the boiler or air handler. Where an automatic air vent is added to the separator body, collected air is purged continuously during system operation.

Key Features

• 2-inch copper press end connections for solderless, torch-free installation
• Brass body construction for corrosion resistance in closed-loop hydronic circuits
• Removes entrained air to protect circulators and improve system efficiency
• Compact in-line design suitable for supply or return main installation
• Compatible with standard press tooling used on copper press fittings

Compatibility

Designed as an OEM-style replacement or new-installation component for 2-inch copper press hydronic piping systems in residential and light commercial applications.

Installation Notes

Installation of this air separator should be performed by a licensed plumber or qualified hydronic system technician. Depressurize and drain the affected section of the hydronic system before removing or installing any component. Copper press connections require a listed press tool with the correct jaw profile for the fitting series. Consult applicable local plumbing codes and IFGC guidelines for system pressure testing requirements after installation.
