This fitting connects two sections of copper tubing using a press-style connection on both ends, eliminating the need for open flame soldering during installation. It is a union-style fitting, meaning the joint can be disconnected and reassembled for serviceability. Licensed plumbers and pipefitters install this type of fitting in systems where torch use is restricted or where faster assembly is required.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial plumbing applications, including domestic water supply lines and hydronic heating distribution piping. Press fittings of this type are commonly installed in tight or confined spaces where torch access is limited or where combustible materials are nearby. The press x press configuration allows the fitting to be used as a break-point union in a copper run for future service access.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress x press end connections on both sides eliminate soldering or brazing\u003c\/li\u003e\n\u003cli\u003eUnion design allows the joint to be broken and reconnected for serviceability\u003c\/li\u003e\n\u003cli\u003e1-inch nominal size suits standard residential and light commercial copper piping\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance in potable water and hydronic applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard press tooling used for copper press fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style press union for use with 1-inch copper tubing in standard plumbing and hydronic piping installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated press tool fitted with the appropriate jaw size for 1-inch copper press fittings. Shut off and depressurize the water supply and drain the line before making or breaking the union connection. Work must comply with applicable local plumbing codes and IAPMO or IPC requirements for press-fit copper fittings. Do not attempt to press a fitting on a wet or pressurized line, as this will result in an incomplete seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PRESU1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51525172527410,"sku":"U1","price":68.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f76e009a539c8d7fa8cf4deb413682da_f5ee342c-72f7-4633-827e-2fff375d4b1a.jpg?v=1785466195","url":"https:\/\/voomisupply.com\/products\/nibco-presu1-copper-press-x-press-union-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
