It serves as a short threaded connector used to join sections of pipe or to connect pipe to fittings, valves, and other threaded components in a piping system. This type of nipple is commonly installed by licensed plumbers and HVAC technicians working on gas distribution, steam, or water systems where black steel pipe is the specified material. The black finish is the standard mill coating applied to carbon steel pipe and is not a protective corrosion coating.\u003c\/p\u003e\n\u003cp\u003eBlack steel pipe nipples like the 588-045HC are used in residential and commercial applications including natural gas supply lines, propane distribution, steam heating systems, and some industrial fluid transfer setups. They are not rated for potable water use. The 2-inch diameter and 4.5-inch length make this nipple suitable for close-quarter connections where a longer run of pipe is not required but a standard close nipple is too short.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch nominal diameter with 4.5-inch overall length for short-run threaded connections\u003c\/li\u003e\n  \u003cli\u003eBlack steel construction standard for gas and steam piping applications\u003c\/li\u003e\n  \u003cli\u003eNPT-threaded ends on both sides for compatibility with standard threaded fittings\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 5 units\u003c\/li\u003e\n  \u003cli\u003eUnit weight supports use in structural piping configurations requiring rigid connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard NPT threaded black steel pipe nipple for use with 2-inch black iron fittings, valves, and couplings in gas, steam, and non-potable fluid piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of black steel pipe nipples on gas lines must be performed by a licensed plumber or gas fitter in accordance with the International Fuel Gas Code (IFGC) and applicable local codes. Apply an approved pipe thread sealant or PTFE tape rated for gas service before threading the nipple into fittings. Shut off the gas supply and confirm zero pressure before disassembling any existing piping. Do not use black steel nipples on potable water or compressed air systems without verifying local code allowance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black (mill coating)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.29 pounds (per package)\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 INDS(IMPORT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 588-045HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51564286738738,"sku":"588-045HC","price":25.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95450cedd1e06053786eb8560c9556a2.jpg?v=1786516374","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-indsimport-588-045hc-black-pipe-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
