{"product_id":"gauge-lock-nut","title":"Waterway Gauge Lock-Nut","description":"\u003cp\u003eThe Waterway 519-7441 is the gauge lock-nut used on the Clearwater II cartridge and DE filters. It is the genuine Waterway part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe pressure gauge sits in a port on the filter and the lock-nut is what holds it there. Small as it is, it is a sealing part. When it cracks or goes missing, the gauge sits loose, weeps at the port and gives you a reading you cannot trust, which matters because filter pressure is how you know when to clean the element.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe nut is plastic, so it is meant to be snugged by hand. Reaching for a wrench is the usual way a new one gets split on the first fit. Order the gauge separately if the gauge itself has failed, since this listing covers the nut alone.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48634765017300,"sku":"WWP-451-2014","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_eae37733-12a3-4dc6-9345-bd6ded630a64.jpg?v=1788836731","url":"https:\/\/www.activepoolsupply.com\/products\/gauge-lock-nut","provider":"Active Pool Supply","version":"1.0","type":"link"}
