About this part
The FR 450 SHITONG ST027 is a precision-engineered flow restrictor cartridge designed to regulate water flow and create optimal back pressure in reverse osmosis (RO) water purification systems. This 450ml capacity restrictor is an essential component that enhances membrane performance and water quality in all types of domestic RO purifiers. The FR 450 SHITONG ST027 features durable plastic construction measuring approximately 8cm in length and 2cm in diameter, with a quick-connect design and two blue locking pins included for secure, leak-proof installation. This flow restrictor works by applying controlled back pressure to the RO membrane, forcing water molecules through the membrane more effectively and producing higher-quality, pure, and better-tasting drinking water. Compatible with all RO membrane sizes up to 150 GPD capacity, the FR 450 SHITONG ST027 is suitable for various RO water purifier models including counter-top, desk-top, stand-mounted, wall-hanging, and under-sink systems. The restrictor prevents excessive water pressure from overwhelming the membrane while optimizing the filtration process. Regular replacement during membrane changes maintains system efficiency and prevents scale buildup in capillaries. The clear flow direction markings ensure correct installation for optimal performance
