Flow Restrictor Capillary Tube Inserts for 1/4" Tubing
Flow Restrictor Capillary Tube Inserts for 1/4" Tubing
Flow restrictors regulate drain line flow in reverse osmosis systems, maintaining proper rejection rates and membrane performance. Each capillary tube insert is color-coded for specific GPD ranges and fits standard 1/4" tubing. Match the restrictor to your membrane capacity for optimal recovery ratios.
Select by membrane capacity and flow rate
| Color | Part Number | Flow Rate | Membrane GPD |
|---|---|---|---|
| Red | FRCT-110 | 110 mL/min | Less than 18 GPD |
| Brown | FRCT-189 | 189 mL/min | 18-24 GPD |
| Black | FRCT-260 | 260 mL/min | 25-36 GPD |
| Yellow | FRCT-365 | 365 mL/min | 36-45 GPD |
| Green | FRCT-525 | 525 mL/min | 45-55 GPD |
| Blue | FRCT-575 | 575 mL/min | 55-75 GPD |
| White | FRCT-730 | 730 mL/min | 70-100 GPD |
| White | FRCT-850I | 850 mL/min | 100+ GPD |
Universal 1/4" tubing applications
Compatible with all standard reverse osmosis systems using 1/4" drain line tubing. Install in drain line between membrane housing and drain saddle. Used in residential and commercial RO systems where controlled reject flow is required for proper TDS rejection. Each restrictor matches specific membrane capacities to maintain ideal concentrate-to-permeate ratios. Order the restrictor rated for your membrane's GPD output.
Good Water Warehouse flow restrictors provide reliable flow control for consistent RO system performance across all membrane capacities.
