It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe o-ring sits at the bulb assembly and is the barrier between pool water and the lamp. It spends its life compressed, warm and submerged, and rubber under those conditions gradually hardens and takes the shape of the groove it sits in. Once that happens it no longer springs back to seal, and the fixture floods.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eChange the o-ring any time the light is opened, especially when the bulb is replaced. Wipe the groove clean, fit the new ring with a thin film of silicone lubricant made for pool o-rings, and keep petroleum based grease well away from it. It is a small part that protects an expensive fixture.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633643827412,"sku":"AMP-301-1263","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ad490007-bce9-4826-be7d-1810c5f08a2b.jpg?v=1788808206","url":"https:\/\/www.activepoolsupply.com\/products\/bulb-assembly-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
