What is a Flushing Ring?

A flushing ring is a ring-shaped component with inlet/outlet ports designed to inject cleaning or flushing fluids into process pipelines. Positioned between a diaphragm seal and the process flange, it enables safe maintenance, prevents blockages, and ensures accurate pressure transmitter performance. This makes it essential in processes involving viscous, crystallizing, or corrosive media.
