Cartridge Wrench for Flushmate Pressure‑Assist Systems

Cartridge wrench ST100500 is designed specifically for servicing Flushmate pressure‑assist toilet systems, providing the secure grip and leverage needed to remove or adjust the flush valve cartridge located at the top center of the pressure vessel. It streamlines maintenance tasks by allowing technicians and facility teams to safely access and service the cartridge without damaging system components. The wrench’s simple, durable design supports reliable daily use in commercial, multi‑unit residential, hospitality, and institutional facilities. Because it is purpose‑built for Flushmate systems, it offers a better fit and safer operation than improvised tools, reducing the risk of overtightening, leaks, or failed cartridge seals.
