REFINEMART RO Flow Restrictor 550 Suitable for All RO Water Purifier Solid Filter Cartridge  (0, Pack of 2)

Re offers RO Reverse Osmosis (RO) FR 550 ML Flows Quick Connect InLine 550 Flow Restrictor. This flow restrictor is to be installed in the drain tubing. The restrictor has 1/4 inch Quick Push Fit Connect fittings. A flow restrictor will create back pressure on the membrane and allow the membrane to produce purified water to be delivered to the pond, aquarium or water tank. Flow restrictors are sized to match the flow with the size of the membrane. In selecting a flow restrictor, be certain you do not "under size" the restrictor as you will prematurely foul the membrane. If you "over size" the restrictor, you will be wasting water but not causing damage to the membrane.
