This fitting is used to transition between two different pipe sizes in a threaded piping system. It is manufactured to meet ANSI\/ASTM A-197 material standards, with dimensions conforming to ANSI\/ASME B16.14 and B16.39, and threads cut to ANSI B1.20.1. The hexagonal body profile allows for a secure wrench grip during installation. Plumbers, pipefitters, and gas-line technicians are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for residential and light commercial plumbing, gas distribution, and industrial pipe systems where a threaded size reduction is required. The black iron construction makes it appropriate for natural gas and propane lines as well as water and air distribution systems. Each fitting ships individually and is flag tagged for easy identification on the job. The Mueller logo is cast into the body of each fitting as a quality identifier.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch male NPT to 1\/2 inch female NPT thread reduction\u003c\/li\u003e\n  \u003cli\u003eBlack malleable iron construction per ANSI\/ASTM A-197\u003c\/li\u003e\n  \u003cli\u003eThreads conform to ANSI B1.20.1 for reliable sealing\u003c\/li\u003e\n  \u003cli\u003eDimensions per ANSI\/ASME B16.14 and B16.39\u003c\/li\u003e\n  \u003cli\u003eHexagonal body for full wrench engagement\u003c\/li\u003e\n  \u003cli\u003e100 percent inspected and quality tested before shipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems requiring a 1-1\/2 inch to 1\/2 inch reduction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Shut off all gas or water supply and relieve system pressure before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a pipe wrench on the hex body only to avoid damage to adjacent piping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Black malleable iron (ANSI\/ASTM A-197)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1-1\/2 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ANSI B1.20.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ANSI\/ASME B16.14, B16.39\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Hexagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00032888309074\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: BK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 521-973HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K","offers":[{"title":"Default Title","offer_id":51346986271026,"sku":"521-973HN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549912.jpg?v=1782095632","url":"https:\/\/voomisupply.com\/products\/bk-521-973hn-black-iron-hex-bushing-1-1-2-x-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
