3M Aqua-Pure, 1/4″ Drain Line Flow Restrictor for RO Systems

The Flow Restrictor for 3M Reverse Osmosis Systems, often known as flow controls or capillaries, are required for reverse osmosis systems. The restrictor must be properly sized to the RO membrane output. This part creates back pressure on the reverse osmosis membrane element and maintains a desired ratio of reject flow and permeate flow.
