{"product_id":"bulkhead-fitting-1","title":"Hayward Bulkhead Fitting for Pro Grid and SwimClear","description":"\u003cp\u003eThe Hayward DEX2420F is the bulkhead fitting used on the Pro-Grid DE filters and the SwimClear cartridge filters. The nut portion of the part carries a DE2420F stamp, which is why owners often find it listed under that second number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a bulkhead fitting does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAnywhere a pipe passes through the wall of a filter tank, something has to carry it and seal it. That is the bulkhead. It is not a glamorous part, but the whole tank depends on it holding, and when it fails the symptom is distinctive: water weeping around the port rather than running out of the plumbing itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck your model\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis fitting is listed across two filter families. On the cartridge side that is SwimClear C2020\/C2025, C3020\/C3025, C4020\/C4025, C5020\/C5025 and C5520. On the DE side it is the Pro-Grid range, and the two sources do not agree exactly: one lists DE2420, DE3620, DE4820 and DE7220, the other adds DE6020. We have carried both lists here rather than choosing one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOne more thing to confirm\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe source describes this item both as a bulkhead fitting and, in one place, as a bulkhead diffuser o-ring.
