0 0


The 500 Milliliter Inline Flow Restrictor for your RO membrane is an essential fitting for maximizing the output of high-quality drinking water from your reverse osmosis system. Getting the right match between your RO membrane element and your inline flow restrictor will ensure the proper pressure and flow balance throughout your system. For maximum performance, replace your restrictor every couple of years--every time you change your RO membrane itself.

  • Effectively creates pressure throughout your RO membrane
  • Maintains the right balance of drinking water (permeate flow) for your RO tank with waste water (reject flow) for your drain
  • Specifically designed for 50 gallon per day membranes
  • Clearly marked with flow rate and flow direction on the restrictor itself
