It is the genuine Pentair part, ordered by number so there is no matching a spring by eye.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy springs get replaced\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA spring that is compressed and released through every cleaning cycle eventually takes a set and stops returning to its original length. Pool water accelerates that, pitting and rusting the metal until it is weak. Neither failure is dramatic, which is what makes it easy to overlook when a cleaner starts behaving oddly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the spring alone, not the filter cartridge or bag. The natural time to change it is when the filter is already out of the cleaner for a wash, because the part costs very little next to the trouble of taking the machine apart twice.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633931595988,"sku":"KPY-201-0724","price":107.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/pentair-360123-kreepy-krauly-legend-ll-filter-spring-mtc56.jpg?v=1788817498","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-360123-spring-filter","provider":"Active Pool Supply","version":"1.0","type":"link"}
