Hayward HEAD

The Hayward Filter Head is a critical structural component engineered to serve as the pressurized lid or upper housing for various pool and spa filtration systems, ensuring a secure and airtight seal during operation. Manufactured from high-strength, glass-reinforced thermoplastic or Hayward’s proprietary PermaGlass XL material, it is designed to withstand significant hydraulic pressure while remaining resistant to UV degradation and the corrosive nature of pool chemicals. This component typically features integrated ports for a manual air relief valve and a pressure gauge, allowing users to safely bleed trapped air and monitor the internal debris load in real-time. The head is often secured to the filter tank using a heavy-duty locking knob or a bolt-around flange system, which provides easy access to the internal cartridges for routine cleaning and maintenance. For shipping and logistical purposes, the estimated weight of a standard Hayward Filter Head is approximately 6.5 pounds in its retail packaging, while the actual weight of the molded head unit itself is roughly 5.4 pounds.
