Hayward ROD 304

the Hayward Rod 304 is a specialized internal structural fastener primarily used in high-capacity cartridge and D.E. filtration systems to maintain the alignment and stability of the filter's internal stack. Manufactured from Grade 304 stainless steel, this rod is specifically chosen for its exceptional tensile strength and its ability to resist oxidation and corrosion in the harsh, chemically active environment of pool water. Its primary mechanical function is to serve as a central anchor that secures the top and bottom manifolds or closure plates together, ensuring that the filter elements or grids remain compressed and properly seated even when the system is operating under maximum hydraulic pressure. By preventing internal components from shifting or lifting, it ensures that all water is forced through the filtration media, preventing bypass and maintaining optimal clarity. For shipping and logistical purposes, the estimated weight of the Hayward Rod 304 is approximately 1.5 pounds in its retail packaging, while the actual weight of the stainless steel rod itself is roughly 1.1 pounds.
