Hayward STAR-CLEAR PLUS FILTER HEAD

The Hayward Star-Clear Plus Filter Head is a structural top-closure component specifically engineered for the Star-Clear Plus series of single-element cartridge filters, including models such as the C751, C900, and C1200. Precision-molded from a heavy-duty, glass-reinforced copolymer (PermaGlass XL™), this head is designed to withstand extreme hydraulic pressures and harsh environmental conditions, including UV exposure and corrosive pool chemicals. Its mechanical design features a rotatable configuration that allows for the convenient positioning of the pressure gauge and the manual air relief valve, ensuring easy monitoring and air purging during system startup. The head is secured to the filter tank body via a single locking knob assembly, which applies uniform downward pressure to the main head O-ring to create a vacuum-tight seal without the need for complex bolts or clamps. This assembly plays a critical role in maintaining system prime and ensuring that all circulating water is directed through the internal cartridge for optimal filtration. For shipping and logistical purposes, the estimated weight of a standard Hayward Star-Clear Plus Filter Head is approximately 5.8 pounds in its retail protective packaging, while the actual dry weight of the molded head component itself is roughly 4.7 pounds.
