Hex bushings are used to connect pipes of different sizes in gas, air, and water distribution systems. This fitting is manufactured to 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. Each unit is individually flag tagged and 100 percent inspected and quality tested before leaving the factory. The Mueller logo is cast directly into the body of each fitting.\u003c\/p\u003e\n\u003cp\u003eThis hex bushing is suited for residential and light commercial piping applications where a threaded pipe size reduction is needed in-line. Typical install scenarios include gas supply lines, compressed air systems, and general plumbing distribution headers. The male thread is sized at 1 inch and the female thread at 3\/4 inch, making this a standard reducing bushing for common pipe transitions. Plumbers and pipefitters working with black iron systems will encounter this style of fitting frequently in both new construction and retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction meets ANSI\/ASTM A-197 material specification\u003c\/li\u003e\n  \u003cli\u003eDimensions conform to ANSI\/ASME B16.14 and B16.39\u003c\/li\u003e\n  \u003cli\u003eThreads cut to ANSI B1.20.1 for consistent, leak-resistant engagement\u003c\/li\u003e\n  \u003cli\u003eHexagonal body allows standard wrench engagement for secure installation\u003c\/li\u003e\n  \u003cli\u003e100 percent inspected and quality tested at the factory\u003c\/li\u003e\n  \u003cli\u003eIndividually flag tagged for easy identification on the job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard component for black iron threaded pipe systems using 1-inch to 3\/4-inch reducing connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of black iron pipe fittings is typically performed by licensed plumbers or pipefitters in accordance with IFGC and IPC requirements for the applicable system type. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly. Do not overtighten — use a properly sized pipe wrench on the hex body to achieve a secure, leak-free connection without stressing the fitting.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 3\/4 inch\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\u003eDimensional Standard\u003c\/strong\u003e: ANSI\/ASME B16.14, B16.39\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.182 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: 521-954BG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K","offers":[{"title":"Default Title","offer_id":51346217730354,"sku":"521-954BG","price":19.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549890.jpg?v=1782074243","url":"https:\/\/voomisupply.com\/products\/bk-521-954bg-black-iron-hex-bushing-1-x-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
