Prevents leaks at critical valve junctions. OEM Part Model 12550 WHAT IT DOES Essential seal for valve integrity The Fleck 12550 quad ring provides a pressure-rated seal at critical points inside the 5600 control valve body. Its four-lobed cross-section design grips more surface area than standard o-rings, reducing the chance of extrusion under cycling pressure. When original seals harden or flatten with age, replacing this component restores leak-free operation during regeneration and service cycles. SPECIFICATIONS Component details Manufacturer Fleck (Pentair) Part Number 12550 Component Type Quad Ring Seal Material Elastomer Application Control valve internal sealing COMPATIBILITY Fits these systems Direct fit for Fleck 5600 control valves used in residential and light commercial water softeners. Confirm part number 12550 in your valve's service manual or existing component before ordering. Compatible with 5600 Standard, 5600 SXT, and 5600 Econominder valve models. 🔧 Field Replaceable Standard component in valve rebuild and maintenance procedures 🛡️ OEM Quality Genuine Fleck part engineered to original specifications 💧 Prevents Leaks Restores pressure seal at valve interface points
