When reassembling the filter housing, inspect the tank O-ring at the same seam; replacing a worn O-ring at the same time prevents a return trip once the filter is back in service. Match the WC19-43 part number against the label on your existing clamp or your filter's parts diagram before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53980244803859,"sku":"WC19-43","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-bottom-v-clamp-without-nut-sta-rite-posi-flo-cartridge-filter-wc19-43.webp?v=1781078265","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_wc19-43","provider":"Poolaroo","version":"1.0","type":"link"}
