It is listed for the System 2 modular media PLM100 and PLM150, and is also carried for the AquaTools permanent media AT84100 and AT84150 and DE AT8230 to AT8236 filters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the date first\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the single thing to get right on this part. Sta-Rite changed the tank o-ring in February 1997. Tanks built before that date take this one; tanks built after take a different o-ring and the two will not substitute for each other. Go by the build date stamped on the filter rather than by when the pool was put in, since filters get replaced without the pool changing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tank o-ring seals the two halves of the filter shell, and it is under pressure every time the pump runs. Clean the groove and the sealing face properly, seat the new ring without twisting it, and dress it with a silicone based lubricant made for pool o-rings. Petroleum grease softens the rubber and will have you back at the same job next season.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48633370575060,"sku":"STA-051-2589","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ef755483-3aad-409f-b814-fde8d661a1f0.png?v=1788798565","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-for-tank-before-2-97","provider":"Active Pool Supply","version":"1.0","type":"link"}
