{"product_id":"r172009z","title":"O-ring Cap for Rainbow Chlorinator","description":"\u003cp\u003eThe O-Ring Cap for Pentair Rainbow Chlorinator (R172009Z) is a replacement o-ring for the threaded cap on Pentair Rainbow automatic chlorinator models 300, 320, 322, 300-19, 300-29, and 300-29X. This o-ring seals the cap to the chlorinator body, preventing chemical-laden water from leaking from the top when the cap is in place. Replace when the cap develops a slow leak or when the o-ring appears cracked, compressed, or chemically degraded. Never use oil or petroleum-based lubricants on chlorinator o-rings -- use only silicone lubricant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e R172009Z\u003c\/p\u003e","brand":"Crystalview Pool, Spa \u0026 Patio","offers":[{"title":"Default Title","offer_id":45319665811500,"sku":"R172009Z","price":15.99,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/www.crystalview.ca\/products\/r172009z","provider":"Crystalview Pool, Spa \u0026 Patio","version":"1.0","type":"link"}
