Flow Restrictors

156 Lee Jet® Single-Orifice Restrictor

This small, economical, and accurate single-orifice flow restrictor contains a calibrated orifice, and two matched safety screens, allowing flow in both directions. This restrictor also features a reliable locking and sealing device. Adapted from Lee Plugs, this locking end design has been accepted for years as the best way to seal drilled holes. Quick and easy to install, this restrictor eliminates the need for costly assemblies, seals, threads, flow testing, and filter design. The Lee Company 100% flow tests all Lee Jet flow restrictors to two standard tolerances, +/- 2% and +/- 5%.
