Seals and lamps often reach end-of-service life on similar intervals — replacing both during the same service visit avoids a repeat disassembly. Verify the part number on your existing seal components matches 523383Z before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53962258710803,"sku":"523383Z","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/2026-04-30_12-51-40.png?v=1777578988","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_523383z","provider":"Poolaroo","version":"1.0","type":"link"}
