This sale is for one (1) Reverse Osmosis Capillary Flow Restrictor. This Capillary Flow Restrictor is a small piece of plastic that is to be inserted into a 1/4 inch tubing and it is usually inserted into the tubing where the tubing is attached to the drain fitting on the membrane housing. A flow restrictor will create back pressure on the membrane and allow the membrane to produce purified water to be delivered to the storage 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.
