When installing, apply a light coat of silicone lubricant to the base threads and gasket, and use plumber’s tape on the gauge threads for a perfect seal. Do not overtighten—filter tank plastic can be brittle.\u003c\/p\u003e\n\u003ch3\u003ePRODUCT FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eGenuine OEM Pentair Part:\u003c\/b\u003e Ensures factory-spec performance and longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh Flow Design:\u003c\/b\u003e Purges trapped air significantly faster than standard valves for safer, more efficient filter priming.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Includes manual relief valve, pressure gauge, and O-ring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUniversal Compatibility:\u003c\/b\u003e Fits a wide range of Pentair and Sta-Rite filter systems, including FNS Plus, Clean \u0026amp; Clear Plus, Predator, Warrior, EasyClean, and SM\/SMBW 4000 Series.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDIY Friendly:\u003c\/b\u003e Designed for a standard \"drop-in\" installation; typically completed in under 5 minutes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003ePart Number:\u003c\/b\u003e 98209800\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e Pentair\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUPC:\u003c\/b\u003e 788379682422\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eValve Type:\u003c\/b\u003e High Flow Manual Air Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions:\u003c\/b\u003e 6\" L x 2-3\/4\" H x 8-1\/2\" W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWHY SHOP WITH AL'S COOL POOL STORE?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Fast, reliable shipping on every order\u003c\/li\u003e\n\u003cli\u003e✅ Genuine OEM and top-tier parts only\u003c\/li\u003e\n\u003cli\u003e✅ Expert pool \u0026amp; spa support\u003c\/li\u003e\n\u003cli\u003e✅ Satisfaction guarantee\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":44921037521031,"sku":"98209800","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0634\/1217\/4983\/files\/pentair-fns-plus-98209800-air-relief-valve-assembly-complete.jpg?v=1781718857","url":"https:\/\/alscoolpoolstore.com\/products\/pentair-98209800-fns-plus-air-relief-valve-assembly","provider":"Al's Cool Pool Store","version":"1.0","type":"link"}
