730 ML Reverse Osmosis RO Capillary Flow Restrictor:
The FRCT-730 insert flow restrictor easily inserts into 1/4" OD tubing located on the reverse osmosis membrane drain line. Many RO units have small insert style flow restrictors that are inserted into the 1/8" X 1/4" elbow that connects the drain tube to the membrane vessel.
This insert flow restrictor is compatible with quick-connect and compression fittings.
This insert flow resterictor is White and used with 100 GPD RO Membranes.
Internal (capillary) flow controls work as brine water flow is restricted by forcing it through a thin capillary tube inside the regular 1/4" drain tubing.
Do not confuse the Insert Flow Restrictor with a tube insert that is only designed to help the tube hold its shape.
INSERT flow restrictors are typically less expensive than INLINE flow restrictors. However, INSERT flow restrictors must be situated correctly to perform correctly and are not as easy to use. We recommend INLINE flow restrictors if possible.
If you install a new inline flow restrictor (see recommended INLINE flow restrictor below), you MUST remove the original INSERT restrictor.
730 ML Insert RO Membrane Flow Restrictor:
Color Code: White
Membrane Size: 100 GPD
Restrictor Tubing Inner Diameter: .042"
Manufacturer: Tier1 FRCT-730
730 ML Capillary RO Membrane Flow Restrictor:
The insert capillary flow restrictor should be changed every time the reverse osmosis membrane is changed.
Be sure that you order the insert capillary flow control ML size to match your reverse osmosis membrane GPD. They must match to operate at the correct efficiency. For the 730 ML flow restrictor, the RO Membrane must be 100 Gallons Per Day.
