A union fitting allows two sections of pipe to be connected and disconnected without rotating either pipe, making it a standard component in service and maintenance applications. Licensed plumbers and pipefitters install this type of fitting where future disassembly is required, such as near equipment shutoffs, appliance connections, or service valves. The black malleable iron construction is suited for dry natural gas, propane, and air service where black iron pipe is specified.\u003c\/p\u003e\u003cp\u003eThis union is appropriate for residential and light commercial piping installations where 1-inch black iron pipe is used. Typical applications include gas supply lines to furnaces, boilers, water heaters, and other gas-fired appliances. It is also used in compressed air distribution and certain industrial fluid systems where malleable iron fittings meet the required pressure and temperature ratings. The three-piece union design includes a female end, male end, and a threaded union nut to draw the two seats together for a secure, leak-resistant joint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch nominal pipe size for standard black iron threaded pipe systems\u003c\/li\u003e\n\u003cli\u003eBlack malleable iron construction compatible with gas, air, and mechanical piping service\u003c\/li\u003e\n\u003cli\u003eThree-piece union design allows pipe disconnection without rotating either pipe section\u003c\/li\u003e\n\u003cli\u003eThreaded ends conform to standard NPT fitting practices for reliable sealed connections\u003c\/li\u003e\n\u003cli\u003eSuited for residential and light commercial gas appliance supply lines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-inch NPT black iron threaded pipe systems in residential and commercial gas and mechanical piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with local mechanical and fuel gas codes, including IFGC and applicable ANSI standards. Shut off and lock out the gas or air supply and verify zero pressure in the line before disassembling any union or fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not overtighten; follow standard NPT hand-tight-plus-turns practice and leak-test all joints with an approved gas leak detection solution before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Black Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: NPT Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\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: MATCO-NORCA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: zmbun05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MATCO-NORCA","offers":[{"title":"Default Title","offer_id":51138353791282,"sku":"ZMBUN05","price":26.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526549.jpg?v=1778254045","url":"https:\/\/voomisupply.com\/products\/matco-norca-zmbun05-1-in-black-malleable-iron-union","provider":"Voomi Supply","version":"1.0","type":"link"}
