{"product_id":"c500-tie-rod","title":"Hayward C500 Tie Rod","description":"\u003cp\u003eThis is the genuine Hayward CX500Z2S tie rod for the Star Clear C500 cartridge filter. It measures 28-3\/32 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tie rod runs down the center of the filter element assembly and pulls the top and bottom plates together against the cartridge. That clamping load is what makes the filter work. Water takes the easiest path available to it, and if the assembly is not held tight, some of the flow slips around the cartridge instead of through it and carries dirt straight back to the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the length matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward shows this rod on the parts diagram covering the Star Clear C-250, C-500, C-750 and C-1000, but the rod itself is sized to the tank. At 28-3\/32 inches this is the C500 part, and a longer or shorter model needs its own. Check the model number on your tank before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTie rods fail by corroding at the threads or by bending under repeated overtightening, and either way the assembly stops clamping properly. If dirt reappears in the pool soon after the filter has been cleaned, or the element stack feels loose when the lid comes off, look at the rod and its hardware. Replace corroded nuts and washers at the same time, since a new rod on a seized nut solves nothing.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634283458772,"sku":"HAY-051-1770","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_8241cb08-e533-481b-a3de-d38666f5e7aa.jpg?v=1788828109","url":"https:\/\/www.activepoolsupply.com\/products\/c500-tie-rod","provider":"Active Pool Supply","version":"1.0","type":"link"}
