It arrives as a set: the drain cap, the O-ring that seals it and the union nut that holds it to the tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch it by the markings\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cap in this assembly is stamped A0118300 and the union nut is stamped A0578900. Those numbers are molded into the parts, so you can pull the old cap off and compare before you order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe drain port is opened every time the tank is emptied for service or winterizing, and the cap takes the wear. A steady drip at the bottom of the filter usually means the O-ring has hardened or the cap has cracked at the threads. Replacing the whole assembly avoids chasing the leak twice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGenuine part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the Jandy factory assembly in plastic, not a generic cap, so the threads and the seal match the tank as built.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48625744412884,"sku":"TLD-051-3100","price":30.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_4114ad0b-47ab-44e4-ac42-d2157adfd0fb.jpg?v=1788690738","url":"https:\/\/www.activepoolsupply.com\/products\/drain-cap-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
