Hayward MANIFOLD ASSY,TOP

The Hayward Top Manifold Assembly is a core internal component designed for multi-element cartridge filter systems, such as the SwimClear series, to ensure uniform water distribution and structural alignment. Precision-molded from high-strength, glass-reinforced thermoplastic, this assembly sits atop the filter cartridge stack and serves as the primary connection point for the internal plumbing and air relief systems. Its mechanical design features specific seated ports that securely lock the top of each filter element in place, creating a pressurized seal that prevents unfiltered water from bypassing the media and entering the return line. This assembly is engineered to withstand constant hydraulic pressure and the harsh chemical environment of pool water while maintaining its rigid shape to prevent internal shifting. For shipping and logistical purposes, the estimated weight of a standard Hayward Top Manifold Assembly is approximately 4.5 pounds in its retail protective packaging, while the actual dry weight of the manifold component itself is roughly 3.8 pounds.
