Premium Hose Thread Pressure Regulation for Drip Systems
Protect your delicate drip irrigation components with the Senninger Lawn & Garden Pressure Regulator (Hose Thread), our absolute best-selling regulator for residential systems. Manufactured by Senninger—a global leader in irrigation pressure control—this compact, 3 1/2″ long unit is designed to safely drop high, fluctuating municipal water pressures down to a steady, reliable output. Engineered with standard 3/4″ Female Hose Thread (FHT) x Male Hose Thread (MHT) connections, it attaches effortlessly to your outdoor spigot, hose timer, or inline hose filter without the need for complicated PVC plumbing.
Built for exceptional longevity, the body is constructed from high-impact engineering-grade thermoplastic and features a rugged stainless steel compression spring inside. Capable of accurately regulating flow rates from 0.5 to 7 Gallons Per Minute (GPM), it guarantees that your downstream drip emitters, micro-sprays, and soaker lines receive the exact pressure they need to operate flawlessly. Available in 10, 20, 30, and 40 PSI preset models, you can choose the precise pressure requirement tailored to your specific garden layout. Please note: This regulator is not rated for constant pressure and must be installed downstream of an automated timer or manual valve.
- Prevents System Blowouts: Safely reduces harsh incoming water pressure (up to 120 PSI depending on the model) to protect your thin-walled tubing and emitters from rupturing.
- Best-Selling Reliability: Backed by Senninger’s world-renowned engineering, featuring a heavy-duty stainless steel internal spring for consistent accuracy.
- Compact Design: At just 3 1/2″ long, it takes up minimal space on your hose bibb, keeping your head assembly neat and low-profile.
- Standard Hose Threads: Designed with FHT x MHT connections for instant, watertight compatibility with standard garden hoses and residential spigots.
- Maintains Uniformity: Ensures that your entire drip zone operates at the exact manufacturer-specified flow rates without pressure-induced fluctuations.

Build your drip irrigation head assembly safely and quickly.
Step 1: Install Your Timer
Attach your hose-end water timer directly to your outdoor water spigot.
Step 2: Add an Irrigation Filter
Thread a hose-threaded screen filter onto the outlet of your timer to protect the internal spring of the pressure regulator from sand and debris.
Step 3: Attach the Pressure Regulator
Thread the Female Hose Thread (FHT) inlet of the Senninger regulator directly onto the filter. Ensure the internal washer is present, and hand-tighten firmly to create a watertight seal. Do not use Teflon tape on hose threads.
Step 4: Transition to Tubing
Thread a standard hose-to-pipe adapter (like a Female Hose Thread to 1/2″ Easy Loc fitting) onto the Male Hose Thread (MHT) outlet of the regulator to connect your poly mainline.
