RO Flow Restrictor 300 to 1000ccÊ/ ML Per Minute Sizes

Reverse Osmosis Flow Restrictor Available in 300cc, 450cc, 500cc, 600cc, 800cc & 1000cc / ML Per Minute Sizes

Flow Restrictors or Capillaries are required for all reverse osmosis systems.

The size of the Flow Restrictor required depends upon the size of the membrane being used.

Flow Restrictors create back-pressure throughout the reverse osmosis membrane element and maintain a ratio of drain water to pure water at around 3 or 4:1. It is recommended that you replace the Flow Restrictor each time you replace your reverse osmosis membrane to keep your system operating at peak efficiency. The number on the flow restrictor indicates the flow rate, in milliliters per minute. The flow restrictor should match your reverse osmosis membrane's production rate.

Inline Flow restrictors are easy to install. They are inserted into the 1/4" Drain Line Tubing. Simply push your 1/4" poly tube firmly into the quick connect fittings located on both the inlet and outlet ends of the flow restrictor and you are done. Flow restrictors are rated by a flow rate expressed as milliliters/minute (ml/min)
