Worn or flattened O-rings are a leading cause of drips at union joints after reassembly — replacing them during the same service visit adds minimal cost and prevents a return trip. Lubricate any O-rings with a silicone-based lubricant before reinstalling. This kit is specified for IntelliFlo3 and IntelliPro3 3.0 HP models — if your pump carries a different horsepower rating, verify the correct union kit part number in your pump's installation manual before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-05-01 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53966170095891,"sku":"410028Z","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-2-2-5-union-kit-intelliflo3-intellipro3-410028z-4.webp?v=1780423365","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_410028z","provider":"Poolaroo","version":"1.0","type":"link"}
