{"product_id":"cord-plug-o-ring","title":"Polaris Genuine OEM Cord Plug O-Ring","description":"\u003cp\u003eThe Polaris R0544100 is the cord plug o-ring for the 9300, 9300xi and 9400 robotic pool cleaners. It measures 21 mm by 2 mm and it is the genuine Polaris part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it protects\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe floating cord plugs into the cleaner, and that joint spends every cleaning cycle submerged. The o-ring in the plug is the only thing between pool water and the electrical connection. It is small and cheap, and it is doing the work that keeps the expensive part of the cleaner dry.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny time the cord is unplugged and the o-ring looks flattened, glazed, nicked or hard, put a new one in. Rubber that has taken a permanent set no longer springs back to fill the groove, so it can look perfectly intact and still let water past. Fit it clean, seat it fully in its groove and push the plug home squarely.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48635043414228,"sku":"POL-201-R0544100","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0f3dd92d-fdf4-4936-b4a8-d22c0ba720e3.jpg?v=1788840584","url":"https:\/\/www.activepoolsupply.com\/products\/cord-plug-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
