1/4 inch Quick Connect Flow Restrictor for RO Water Purifiers 150, 300, 450, 600, 1000 cc What it does This 1/4 inch quick connect flow restrictor regulates wastewater flow on reverse osmosis systems to match the specified flow rate option (150, 300, 450, 600, or 1000 cc). It installs inline with standard 1/4 inch tubing to help maintain correct draintoproduct ratios and stable system operation. Key benefits Accurate flow control: Provides a consistent drain flow corresponding to the selected cc rating to help the RO system operate as intended. Easy installation and replacement: Quick connect design fits standard 1/4 inch tubing for fast pushin connection without tools. Stable system performance: Helps prevent excessive backpressure and supports proper membrane function by keeping flow within designed limits. Flexible compatibility: Works with most reverse osmosis and RO water purifier assemblies that use 1/4 inch quick connect fittings. Durable construction for routine service intervals: Built for repeated installations and straightforward part swaps during maintenance. Features and specifications Connection type: 1/4 inch quick connect fitting for pushin tubing. Available flow options: 150 cc, 300 cc, 450 cc, 600 cc, 1000 cc. Function: Inline flow restrictor for RO drain line to control wastewater volume. Compatibility: Designed for reverse osmosis and RO water purifiers using 1/4 inch tubing and quick connect fittings. Performance: Provides predictable flow rates to match membrane and system design parameters. Practical applications a worn or clogged restrictor on an undersink RO system to restore correct drain flow and stabilize tank filling rates. Modify system flow characteristics when swapping membranes or adjusting production by choosing the appropriate cc rating for the configuration. Use during installation of countertop or pointofuse RO units that require a specific drain flow rate to balance permeate and concentrate outputs. Installation notes Push tubing fully into the quick connect until it seats; pull back slightly to confirm secure fit. Choose the restrictor with the cc rating that matches system requirements or installer guidance. Inspect tubing for cuts or damage and tubing if to ensure a reliable seal. This 1/4 inch quick connect restrictor provides a simple, serviceable way to control RO drain flow and maintain consistent system operation across common reverse osmosis setups.
