The WR-4W wrench is designed for PureT 908 and 907 series Big Blue filter housings, as well as Intelifil GTS series housings that share the same sump diameter and thread pattern. This tool is essential for whole-house filtration systems, well water applications, and commercial installations where housings are serviced quarterly or semi-annually.
