  • This sale is for one (1) Reverse Osmosis Capillary Flow Restrictor for RO Membrane drain
  • 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.
OUR FLOW RESTRICTOR COLOR MAY BE CODED DIFFERENTLY FROM OTHER MANUFACTURES.
