This part is the bottom half. If the shell has cracked, split at the clamp lip or gone chalky and brittle with age, it has to be replaced rather than repaired, because the tank is a pressure vessel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat carries over\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cartridges or grids, the internal assemblies and the plumbing connections all move to the new shell. While the filter is open it is worth checking the lock ring, the safety latch and the tank body O-ring, since those are the parts that wear alongside the shell.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGenuine part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the factory shell, sold under the Sta-Rite and Pentair names, so it matches the original mating surface and the lock ring already on your filter.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48625744478420,"sku":"STA-051-2580","price":523.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_f85fed0f-6cf1-40bc-8abb-42a6611fd126.jpg?v=1788690746","url":"https:\/\/www.activepoolsupply.com\/products\/lower-tank-shell-half-plm-pld","provider":"Active Pool Supply","version":"1.0","type":"link"}
