The MacDonald Plumbing Supplies Dosing Funnel provides a fast, clean, and convenient method of introducing inhibitors, sludge removers, and other heating system treatment chemicals into a central heating system via a radiator. Supplied with a ½" BSP adaptor, it connects directly to the radiator, allowing chemicals to be poured into the system with minimal mess.
