3/4" FHT X 3/4" MHT Senninger Pressure Regulator. Reduces the pressure entering the drip irrigation system. Use with other garden hose thread fittings. Choose the appropriate preset PSI rating for your application (normally 25 PSI for tubing and 10 PSI for tape).
Special notes: This pressure reducer is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.
