It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a half union is\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA union joins two lengths of pipe with a threaded collar so that the joint can be taken apart by hand. This listing is one half of that assembly, the adapter that goes on the filter side. It is worth being clear about which half you are missing before ordering, since the two sides are not interchangeable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy unions matter on a filter\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFilters have to come off for service, and without unions that means cutting and re-gluing pipe every time. A sound union is the difference between a fifteen minute filter pull and an afternoon of plumbing. When you reassemble one, check the o-ring in the joint. A union that drips is far more often a hardened seal than a failed adapter.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634494943444,"sku":"SWQ-051-8322","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_6faa2e33-af4c-4b30-aabc-788a92428bb3.png?v=1788832804","url":"https:\/\/www.activepoolsupply.com\/products\/2-union-adapter","provider":"Active Pool Supply","version":"1.0","type":"link"}
