Nibco h-70700 Magnetic Dirt Separator 1 Inch

Product Description

The NIBCO h-70700 is a 1-inch magnetic dirt separator filter designed for hydronic heating systems, including residential and light commercial boiler installations. The unit captures ferrous particles and non-magnetic debris circulating through the system, protecting pumps, valves, and heat exchangers from fouling and premature wear. It ships as a body-only assembly with G-unions included, allowing for straightforward in-line installation. Licensed plumbers and hydronic heating technicians are the primary installers of this type of component.

This separator is suited for closed-loop hydronic systems where water quality and system cleanliness are critical to long-term equipment performance. Typical applications include baseboard hot-water heating, radiant floor systems, and boiler primary loops where iron oxide sludge and magnetite buildup are common concerns. The included G-unions simplify servicing by allowing the separator body to be removed for cleaning without draining the entire system.

Key Features

• Magnetic core captures ferrous particles including magnetite and iron oxide sludge
• 1-inch connection size suits common residential and light commercial hydronic piping
• Body-only configuration ships with G-unions for easier installation and future servicing
• G-union connections allow body removal for cleaning without full system drain-down
• Designed for in-line installation in boiler supply or return piping

Compatibility

Designed as an OEM-style replacement and new-installation component for 1-inch hydronic heating piping in residential and light commercial boiler systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician. Shut down the boiler and allow the system to depressurize and cool before installing or servicing this separator. Follow all applicable local plumbing codes and the International Plumbing Code (IPC) for hydronic system work. Do not overtighten the G-union connections; follow the fitting manufacturer torque guidance and inspect for leaks after system repressurization.
