Hayward DIAPHRAGM GASKET

The Hayward Diaphragm Gasket is a heavy-duty, circular sealing component engineered to provide a hermetic, pressure-tight barrier between the filter head and the main tank body in D.E. filtration systems. Manufactured from a high-performance, chemical-resistant elastomer, this gasket is designed to maintain its elasticity and structural integrity while subjected to the constant hydraulic pressure and thermal fluctuations of a pool equipment pad. Its primary mechanical function is to seal the interface of the two main tank halves, preventing water and filtration media from leaking out while allowing for the subtle internal movements required during the "bumping" process. The gasket’s wide-profile design ensures a large surface area of compression, which is vital for maintaining a secure seal even as the tank expands and contracts. Formulated to resist the corrosive effects of salt-chlorine generators and standard sanitizers, this component prevents pressure loss and ensures the filtration system remains primed for efficient operation. For shipping and logistical purposes, the estimated weight of the Hayward Diaphragm Gasket is approximately 1.6 pounds in its retail protective packaging, while the actual dry weight of the individual elastomeric seal is roughly 1.1 pounds.
