{"product_id":"clamp-bolt-and-nut","title":"Hayward Clamp Bolt and Nut","description":"\u003cp\u003eThe Hayward DEX2421J2 is the clamp bolt and nut used on SwimClear cartridge filters and Pro-Grid DE filters. It is the genuine Hayward hardware, supplied as the bolt and its nut together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy this small part matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe band clamp around a filter tank only holds pressure because this bolt can still be drawn up tight. Bolts in a wet equipment pad corrode, stretch and round off at the head, and once that happens the clamp cannot be torqued evenly. Owners usually notice it as a slow weep at the tank split, or as a bolt that will not come loose at teardown.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt covers SwimClear models C2020 through C7000, the C2030 through C7030 range, and the Pro-Grid DE2420, DE3620, DE4820, DE6020 and DE7220 DE filters.
