This union allows technicians to disconnect and reconnect a piping section without cutting pipe, making it a practical choice for service access points and future maintenance locations. The press-style end connections eliminate open-flame soldering, speeding up installation and reducing fire risk in occupied structures. Licensed plumbers and pipefitters are the primary installers of this fitting type.\u003c\/p\u003e\u003cp\u003eThe PRESU112 is suited for residential and light commercial plumbing, hydronic heating, and radiant systems where 1-1\/2 inch copper main lines require a serviceable union connection. Press fittings are commonly used in mechanical rooms, boiler rooms, and retrofit applications where torch work is restricted or impractical. This fitting is installed inline on straight copper tube runs where future disassembly may be required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress x press end connections eliminate the need for open-flame soldering\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch connection size suits main distribution lines in residential and light commercial systems\u003c\/li\u003e\n\u003cli\u003eUnion design allows the piping section to be disconnected and reassembled for service access\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance suitable for potable water and hydronic fluid service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-service fitting for 1-1\/2 inch copper tube press piping systems in plumbing and hydronic heating applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a manufacturer-approved press tool with the correct jaw size for 1-1\/2 inch press fittings. Shut off and depressurize the system completely before disassembling or pressing any connection. Work must comply with applicable local plumbing codes and ASTM standards for copper press systems. Verify that the press ring or sleeve is fully seated before actuating the press tool to ensure a leak-free joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Press x Press\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Style\u003c\/strong\u003e: Union\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: PRESU112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51524774002994,"sku":"U112","price":114.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f76e009a539c8d7fa8cf4deb413682da_ed7974c1-e5e3-4f4c-9925-32ff2dfec781.jpg?v=1785457167","url":"https:\/\/voomisupply.com\/products\/nibco-presu112-copper-press-union-1-1-2-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
