We have a Flow Restrictor 420 ML for Reverse Osmosis RO Systems with quick connections. Quick connections allow this to be installed and uninstalled easily. This replacement inline flow restrictor can be be used when replacing your membrane with a higher or lower flow capacity.
This is the standard size for the 50 gpd RO system. This is a 420 ml size, you can use anywhere from a 350-500 ml size on the 50 gpd reverse osmosis system.
Flow Restrictor restricts the flow of reject water in water's drain line that leaves the membrane. It provides resistance by creating pressure against the membrane and forcing some of the product water through the membrane.
