Hydronamic (FR2000JD) Flow Restrictor 1/4" Quick Connect
Hydronamic FR2000JD Flow Restrictor with 1/4" Quick Connect
Precision flow metering for reverse osmosis systems, engineered with integrated quick-connect fittings for reliable drain line regulation from 80 to 2000 milliliters per minute.
Engineered for Consistent RO Performance
Integrated Quick Connects
Both 1/4" tubing connections built directly into the restrictor body. No separate fittings, fewer potential leak points, faster installation on any RO drain line.
Wide Flow Range
Available in 18 distinct flow rates from 80 ml/min to 2000 ml/min. Match your restrictor precisely to your membrane GPD rating and system design requirements.
Membrane Protection
Maintains proper backpressure on the RO membrane to ensure optimal rejection rates and protect the membrane from premature fouling or damage.
Compact Form Factor
Small inline design fits tight installation spaces. Simplifies routing in under-sink cabinets and commercial equipment enclosures without bulky hardware.
Available Flow Rates
The Hydronamic FR2000JD series includes the following model numbers, each calibrated for a specific flow rate: FR2000JD-80 (80 ml/min), FR2000JD-100 (100 ml/min), FR2000JD-200 (200 ml/min), FR2000JD-250 (250 ml/min), FR2000JD-300 (300 ml/min), FR2000JD-350 (350 ml/min), FR2000JD-400 (400 ml/min), FR2000JD-420 (420 ml/min), FR2000JD-500 (500 ml/min), FR2000JD-600 (600 ml/min), FR2000JD-700 (700 ml/min), FR2000JD-750 (750 ml/min), FR2000JD-900 (900 ml/min), FR2000JD-1000 (1000 ml/min), FR2000JD-1500 (1500 ml/min), and FR2000JD-2000 (2000 ml/min). Select the flow rate that matches your RO membrane specifications and desired waste-to-product water ratio.
Tool-Free Installation
Push-to-connect fittings accept 1/4" tubing instantly without clamps or threading
Maintains System Pressure
Consistent backpressure ensures membrane longevity and optimal TDS rejection
Universal RO Application
Works with all standard reverse osmosis systems using 1/4" tubing
Compact Inline Design
Minimal footprint for easy integration into any filtration setup
