High-precision 1/4 inch pressure regulators engineered for water systems and ultra-low pressure applications. These manual control regulators deliver hysteresis-free operation with precise pressure regulation from 0-3 inches of water up to 0-5 psi, ideal for medical tubing extrusion, catheter manufacturing, and automotive applications.


While both control pressure, a pressure regulator maintains consistent downstream pressure regardless of variations in inlet pressure or flow demand, while a pressure reducer simply lowers inlet pressure to a set lower pressure. Our 1/4 inch pressure regulators feature hysteresis-free operation with 30-turn precision adjustment, providing stable pressure control from 0-3 inches of water up to 0-5 psi for critical applications.
