Pentair lists it for all residential BioShield models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it covers\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA UV sterilizer seals pool water around a quartz sleeve with the lamp running dry inside it. The o-rings are the only thing keeping those two worlds apart, and they take heat every hour the system runs. Supplying them as a kit means every seal you disturb during a service goes back new instead of being reused because it looked fine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to use it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFit the kit whenever the sleeve or lamp comes out. Reusing hardened o-rings after a lamp change is the most common reason a BioShield weeps afterwards. The lamp and the quartz sleeve themselves are separate Pentair parts.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627619004628,"sku":"PAC-451-0587","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_6f6f91ab-d8d0-4dcd-951a-f7e54c17bf19.png?v=1788725424","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-523031-bioshield-uv-o-ring-service-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
