REPLACEMENT Inline Flow Restrictor for 50 GPD RO w/ Quick-Connect Fittings.
Can replace other types ( older units had Restrictor In the FITTING and if you have that, you should change the FITTING to JGCI480821W ).
Some older styles include the drain fittings with built-in restrictors or another called "capillary" flow restrictors that insert into one end of the drain tube.
