performance in residential and commercial water softeners OEM Part Fleck Certified Injection System COMPONENT DETAILS Precision-molded cap for Fleck valve injector assemblies The Fleck 40556 injector cap secures the venturi assembly inside Fleck control valves, creating the sealed chamber necessary for proper eductor function during regeneration cycles. This cap threads directly onto the injector body and maintains compression on the o-ring seal that prevents air intrusion and ensures consistent brine draw rates. Used across multiple Fleck valve series including 5600, 7000, and 9000 platforms. Part Number Fleck 40556 Component Type Injector cap assembly Material Engineered polymer composite Thread Type Standard Fleck injector thread Application Control valve injector sealing Compatible Brands Fleck control valves COMPATIBILITY Fleck valve platforms The 40556 injector cap fits Fleck 5600, 5600SXT, 7000, 7000SXT, 9000, and 9100SXT control valves. This cap works with standard injector assemblies across residential and light commercial softener installations. Verify your existing injector body threads match Fleck OEM specifications before ordering. Compatible with both metered and timer-based valve configurations. WHEN TO REPLACE Signs of injector cap failure Inspection Point During injector service Replace the cap whenever servicing the injector assembly, especially if threads show wear or if the cap no longer tightens securely Performance Issue Loss of brine draw A cracked or cross-threaded cap can break the venturi seal, causing incomplete regeneration and reduced softening capacity Visual Damage Cracks or thread damage Replace immediately if the cap shows stress cracks, stripped threads, or won't maintain proper torque on the injector body 🔧 OEM Fleck Part Factory component ensures exact fit and material compatibility with Fleck injector assemblies 💧 Restores Brine Draw Properly sealed injector maintains venturi vacuum for consistent salt delivery during regeneration ⚙️ Cross-Platform Fit Single part number covers multiple Fleck valve series from 5600 through 9100 platforms 🛠️ Service Essential Keep spare caps on hand for injector maintenance and emergency repairs on commercial installations
