Overtightening a plastic union nut can crack the fitting — snug and leak-free is the target, not maximum force. Inspect the union O-ring at the same time; a worn O-ring is the most common cause of leaks at this connection and should be replaced whenever the nut is removed.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774207426835,"sku":"SPX1500G","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-union-nut-for-powerflo-lx-pumps-w3sp1580-w3sp1580x15-spx1500g-1.webp?v=1788751566","url":"https:\/\/poolaroo.com\/products\/hayward-powerflo-union-nut-spx1500g","provider":"Poolaroo","version":"1.0","type":"link"}
