The press-style connection eliminates the need for open flame soldering, allowing the fitting to be installed quickly using a compatible press tool. This union configuration allows for in-line disconnection and reconnection of copper tubing sections, making it useful for service access points. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit applications where flame-free joining is required or preferred.\u003c\/p\u003e\n\u003cp\u003eThe PRESU12 is suited for residential and light commercial plumbing systems, including domestic water supply, hydronic heating loops, and similar closed-loop fluid systems. The press x press end configuration means both ends accept press-tool actuation, requiring no soldering, brazing, or thread preparation. It is particularly useful in occupied spaces or areas where torch work is restricted by code or site conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress x press end connections on both sides eliminate open-flame soldering\u003c\/li\u003e\n  \u003cli\u003eUnion design allows in-line disconnection for service or system modification\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch nominal size fits standard 1\/2 inch copper press tubing\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in water and hydronic fluid service\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard press tooling used for copper press systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press union for 1\/2 inch copper press-connect plumbing systems.

Shut off and depressurize the water supply line before cutting into any existing system. Ensure the tube end is clean, deburred, and fully inserted to the depth mark before pressing. Follow local plumbing code requirements, including IPC provisions, for approved press-fitting applications and inspection procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Press x Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PRESU12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51524409524530,"sku":"U12","price":36.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f76e009a539c8d7fa8cf4deb413682da.jpg?v=1785448291","url":"https:\/\/voomisupply.com\/products\/nibco-presu12-copper-press-union-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
