Clear (154566Z) is the OEM replacement sight glass for Pentair's 2 In. Hi-Flow Valve and 2 In. PVC Slide Valve series.\u003c\/p\u003e\n\u003cp\u003eThe clear sight glass provides a visual inspection port on the valve body, allowing you to confirm water flow and clarity without disassembling the valve. A cracked, clouded, or leaking sight glass compromises your ability to monitor valve operation and can allow water to escape the system at the valve housing — replacing it with the correct OEM part restores both function and a watertight seal.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e154566Z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eSight Glass 2 In.

Inspect the threaded nipple on your existing sight glass for any thread damage or sealant buildup before installation; clean threads thoroughly to ensure a leak-free fit on the new part.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960101134611,"sku":"154566Z","price":13.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-sight-glass-2-in-clear-for-hi-flow-slide-valves-154566z.webp?v=1787788994","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_154566z","provider":"Poolaroo","version":"1.0","type":"link"}
