{"product_id":"closure-6-v-thread-tan-only","title":"Pentair Genuine OEM Closure 6\" V Thread, Tan","description":"\u003cp\u003eThe Pentair 154559Z is the tan 6 inch V thread top closure, the dome lid for PacFab TR Triton sand filters built before 12-1-91. It is the genuine Pentair part, molded in plastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the date before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the detail that trips people up. Pentair listed this closure for TR Triton filters made before 12-1-91, and the closure design changed after that. A filter that looks identical from across the pad can take a completely different lid, so find the date on your filter and confirm the thread type before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eV thread against buttress thread\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe two threads look similar until you put them side by side. V threads are pointed in profile, buttress threads are squared. Pentair also lists an 8-1\/2 inch buttress thread top closure as its own part, so if that is what your filter takes, this is not the right lid.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are at it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA closure that has been on a filter for decades has usually been sealing against an o-ring of the same age. Those seals are listed separately, and it is worth replacing them at the same time rather than opening the filter twice.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633369395412,"sku":"PAC-051-5742","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_dd198ab2-0540-4a22-8db2-5b87661817b2.png?v=1788798458","url":"https:\/\/www.activepoolsupply.com\/products\/closure-6-v-thread-tan-only","provider":"Active Pool Supply","version":"1.0","type":"link"}
