They are the genuine Hayward parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich filters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward lists this o-ring for the Super StarClear cartridge filter, the ProGrid and MicroClear vertical grid DE filters, ProSeries Plus, and ProSeries sand filters. Two come in the pack, which is useful because unions seal at each end and a spare on the shelf saves a second trip.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy they leak\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnion and valve o-rings sit compressed for years. The rubber hardens, takes a permanent set in the shape of the groove, and stops following the joint as it flexes. The result is a fitting that looks dry at rest and weeps the moment the pump starts and pressure comes up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eShut the system down and relieve pressure first. Clean the groove, check the sealing face for scoring, and seat the new o-ring lightly lubricated so it does not roll or pinch as the union is tightened.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48628897382612,"sku":"HAY-051-2253","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_332a7f0e-9648-46e7-a25b-f82fc42b136b.png?v=1788757098","url":"https:\/\/www.activepoolsupply.com\/products\/hayward-sx200z4pak2-valve-union-o-ring-2-pack","provider":"Active Pool Supply","version":"1.0","type":"link"}
