OEM Hayward Bulkhead Fitting DEX2420F is engineered to provide a leak-resistant seal in Hayward Pro-Grid DE filters, DEP 500 Series, and SwimClear models C2020 through C5020. This essential component connects internal filter parts to the external plumbing system, ensuring proper water flow and maintaining filtration pressure. Built from heavy-duty, chemical-resistant materials, it resists damage from chlorine exposure and pool system pressures. Since most filter systems require two bulkhead fittings, replacing worn or cracked fittings like the DEX2420F is crucial to avoiding leaks and sustaining reliable filter performance.
