{"product_id":"spring-compression","title":"Pentair Genuine OEM Compression Spring","description":"\u003cp\u003eThe Pentair 178616 is a metal compression spring used inside Pentair filters. It is listed for the Clean and Clear Plus cartridge filter and for the EasyClean aboveground DE filter system, and it is the genuine Pentair part rather than a generic spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA small part that is easy to overlook\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSprings do not usually announce themselves. They corrode, they lose tension, and the filter goes on working badly until someone opens it up. When a Pentair filter is apart for a cartridge or grid change, a corroded or collapsed spring is the sort of piece worth renewing then and there rather than putting the tank back together around it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair uses several springs across its filter range, and they are not interchangeable. Check 178616 against the parts list for your exact filter model, and if you are working from a spring you have already pulled out, compare it against the photo before you buy.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628815986900,"sku":"PAC-051-1678","price":12.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_199cbb09-56a5-4d82-8710-d4bae8475de2.png?v=1788752392","url":"https:\/\/www.activepoolsupply.com\/products\/spring-compression","provider":"Active Pool Supply","version":"1.0","type":"link"}
