Magnetic Boiler Filter XL from Webstone, a brand of NIBCO

Mechanical Hub 2025The Magnetic Boiler Filter XL is designed to protect larger residential boilers from iron sludge that can accumulate in a hydronic system. Commonly installed on the system run, it captures ferrous and non-ferrous debris before it can reach the boiler using a high-powered 12,000 Gauss magnet and plastic filter.

The drain makes it simple to remove accumulation, with a strapped cap that can be used to actuate the drain valve and a large filter body that increases time between service. A service tool is also included to help install and maintain the filter with ease. G-threads make it simple to swap out your choice of press, MIP, FIP, or sweat G-union end connections in sizes 1¼” or 1½”. The MBF XL can withstand 250°F and 145 PSI CWP.
