Sized at 0.75 inches nominal diameter and 12 inches in length, this close-threaded nipple is a standard component in low-pressure piping assemblies. It is commonly installed by licensed plumbers and pipefitters working on residential and light commercial systems. The black finish indicates untreated steel, which is the accepted standard for natural gas and propane distribution piping where corrosion protection is provided by the surrounding system design.\u003c\/p\u003e\u003cp\u003eThis nipple fits into standard threaded piping layouts wherever a 0.75-inch diameter, 12-inch extension is required. Typical applications include gas supply lines, compressed air distribution, and industrial fluid transfer. The 12-inch length makes it suitable for spanning short gaps between fittings, valves, and equipment connections without the need for field-cut pipe. It is packaged 15 pieces per unit and sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.75 inch nominal diameter with standard NPT threads on both ends\u003c\/li\u003e\n\u003cli\u003e12 inch body length for short-span pipe extensions\u003c\/li\u003e\n\u003cli\u003eBlack steel construction — accepted for natural gas and propane supply lines per IFGC guidelines\u003c\/li\u003e\n\u003cli\u003eThreaded ends compatible with standard NPT fittings, valves, and couplings\u003c\/li\u003e\n\u003cli\u003eSold individually; packaged 15 per unit for job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for standard 0.75 inch NPT threaded piping systems in gas, air, and fluid distribution applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) where gas service is involved. Shut off the gas supply or system pressure and depressurize the line before threading or unthreading any nipple. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all NPT threads before assembly. Do not over-tighten threaded connections; use a pipe wrench and backup wrench to avoid stressing adjacent fittings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Black steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT (both ends)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 16.49 pounds (per package of 15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 15 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: B K Mueller Industries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 584-120HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51559583220018,"sku":"584-120HN","price":59.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c4623405dc08082b8185483726955e6_c60b0ada-345e-4acb-a4ea-f068272bd93b.jpg?v=1786435983","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-584-120hn-black-steel-pipe-nipple-3-4x12","provider":"Voomi Supply","version":"1.0","type":"link"}
