Stress fractures around the port openings are common on filters of this vintage and will continue to leak even with new unions installed. If the port area shows damage, the filter tank itself may need replacement rather than just the unions.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-05-01 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":51774169448723,"sku":"98960311","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN98960311_0.jpg?v=1747701993","url":"https:\/\/poolaroo.com\/products\/pentair-bulkhead-union-kit-black-98960311","provider":"Poolaroo","version":"1.0","type":"link"}
