Union nuts typically show wear at the threads and locking tabs before the union body fails — replacing the nuts while the union is already apart saves time and avoids a second service call. Hand-tighten union nuts only; over-tightening with tools can crack the nut or distort the thread engagement.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774178918675,"sku":"HAXNUT1930","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-union-nuts-for-hayward-pool-equipment-plumbing-unions-set-of-2-haxnut1930-2.webp?v=1787739311","url":"https:\/\/poolaroo.com\/products\/hayward-h-series-heater-union-nuts-2-pack-haxnut1930","provider":"Poolaroo","version":"1.0","type":"link"}
