Hayward DIAPHRAGM GASKET -EC30-

The Hayward Diaphragm Gasket for the Perflex EC30 series is a heavy-duty, flexible sealing component designed to create a hermetic barrier between the filter head and the main tank body. Precision-molded from a high-grade, chemical-resistant elastomer, this large circular gasket is engineered to withstand the constant hydraulic pressure and thermal expansion characteristic of a pressurized D.E. filtration system. Its primary mechanical function is to prevent pressurized water and Diatomaceous Earth from leaking out of the vessel, while also providing the necessary flexibility to accommodate the movement of the internal tube sheet assembly. The gasket features a specific profile that seats into the tank flange, ensuring a watertight seal even during the mechanical stress of the bumping process used to regenerate the filter media. Because it serves as the primary pressure seal, the material is formulated to resist drying, cracking, or losing its elasticity when exposed to pool chemicals and fluctuating outdoor temperatures. For shipping and logistical purposes, the estimated weight of the Hayward Diaphragm Gasket for the EC30 is approximately 1.4 pounds in its retail protective packaging, while the actual dry weight of the individual elastomeric gasket is roughly 0.95 pounds.
