Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and equipment in low-pressure gas, air, and fluid distribution systems. This nipple features male NPT threads on both ends and is manufactured from black steel, making it well-suited for gas supply lines, compressed air systems, and general-purpose plumbing applications. Plumbers, pipefitters, and gas technicians install nipples like this one as part of routine rough-in and service work.\u003c\/p\u003e\n\u003cp\u003eThis nipple is commonly used in residential and light commercial settings where black iron pipe assemblies are required. Typical applications include natural gas and propane supply piping, boiler and heating system connections, and compressed air distribution. The 3\/4 inch size is one of the most common trade sizes encountered in residential gas rough-in and commercial mechanical rooms. It is sold in a package of 20 units, making it practical for contractors stocking supply for multi-unit or production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBlack steel construction suitable for gas, air, and general fluid piping\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch nominal diameter with 4.5 inch overall length\u003c\/li\u003e\n  \u003cli\u003eMale NPT threads on both ends for standard fitting compatibility\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 20 for contractor-level purchasing\u003c\/li\u003e\n  \u003cli\u003eEach unit sold individually (EA unit of measure)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard black steel pipe nipple compatible with 3\/4 inch NPT fittings, valves, and couplings used in residential and commercial gas and air piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBlack steel pipe nipples are installed by licensed plumbers or gas fitters in accordance with local mechanical codes and IFGC requirements. Before servicing or replacing any nipple in a gas line, shut off the gas supply at the meter or upstream valve and verify zero pressure with a manometer. Apply listed pipe thread sealant or PTFE tape rated for gas service to all male threads before assembly. Do not use on potable water systems where black steel is not code-approved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.5 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\u003ePackage Quantity\u003c\/strong\u003e: 20 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 7.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: B K Mueller Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 584-045HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51560718532914,"sku":"584-045HN","price":33.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6909acbd1e257f40ef826e9b16a185a1.jpg?v=1786456125","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-584-045hn-black-pipe-nipple-3-4x4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
