Hayward TIE ROD

The Hayward Tie Rod is a critical structural fastener designed to maintain the internal alignment and pressurized integrity of cartridge and D.E. filtration systems. Typically manufactured from solid stainless steel to resist corrosion and chemical degradation, this threaded rod runs through the center of the filter tank to bridge the gap between the top and bottom manifolds or the filter head and base. Its primary mechanical function is to provide a high-tensile anchor point that secures the internal components together, ensuring that filter cartridges or grids remain perfectly seated and vertical even under intense hydraulic pressure. By preventing internal shifting, the tie rod ensures that water is forced through the filtration media rather than bypassing it, which is essential for maintaining consistent water clarity and preventing pump surging. For shipping and logistical purposes, the estimated weight of a standard Hayward Tie Rod (such as those used in the Star-Clear or ProGrid series) is approximately 2.0 pounds in its retail packaging, while the actual weight of the stainless steel rod itself is roughly 1.2 pounds, depending on the specific model length.
