OEM Hayward DEX2420F Bulkhead Fitting is a high-performance replacement part designed for Pro-Grid DE filters, DEP 500 Series filters, and SwimClear cartridge filters including models C2020, C3020, C4020, and C5020. This fitting forms a watertight seal between the filter tank and external plumbing, preserving circulation efficiency and system pressure. Constructed from chemical-resistant, high-strength materials, it withstands the wear of constant exposure to pool chemicals and operating pressures. Each system generally requires two bulkhead fittings, making routine inspection and replacement essential to prevent leaks and maintain optimal filtration performance.
