This type of fitting is a standard component in gas, air, and low-pressure fluid piping systems. The hexagon body profile allows for wrench engagement during installation. Each fitting is individually flag tagged and carries the Mueller logo cast directly into the body. Material conforms to ANSI\/ASTM A-197, dimensions conform to ANSI\/ASME B16.14 and B16.39, and threads are cut to ANSI B1.20.1. Plumbers and pipefitters use this bushing wherever a threaded pipe run requires a reduction in nominal pipe size at a fitting connection point.\u003c\/p\u003e\u003cp\u003eThis hex bushing is suited for residential and light commercial piping applications including gas supply lines, compressed air distribution, and water service piping. The 1-1\/2 inch male thread connects into a larger fitting or valve body, while the 1 inch female thread receives the smaller downstream pipe or fitting. Its malleable iron construction provides the ductility needed to withstand mechanical stress in threaded assemblies. This fitting is sold individually and ships as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBlack malleable iron construction conforming to ANSI\/ASTM A-197\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch male NPT x 1 inch female NPT reduction\u003c\/li\u003e\n\u003cli\u003eHexagon body allows standard wrench engagement for proper tightening\u003c\/li\u003e\n\u003cli\u003eThreads cut to ANSI B1.20.1 for consistent fitment with standard NPT pipe and fittings\u003c\/li\u003e\n\u003cli\u003eDimensions comply with ANSI\/ASME B16.14 and B16.39\u003c\/li\u003e\n\u003cli\u003e100 percent inspected and quality tested before shipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting compatible with standard 1-1\/2 inch male NPT and 1 inch female NPT threaded pipe systems using black iron or malleable iron components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable local codes and IFGC or IPC requirements depending on service type. Shut off and depressurize the piping system fully before disassembling any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque; use the hex body with a fitting wrench to achieve a proper sealed connection without cracking the fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eConnection Size (Male)\u003c\/strong\u003e: 1-1\/2 inches NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size (Female)\u003c\/strong\u003e: 1 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 Standards\u003c\/strong\u003e: ANSI\/ASME B16.14, B16.39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.147 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 521-975BG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K","offers":[{"title":"Default Title","offer_id":51344017457458,"sku":"521-975BG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549910.jpg?v=1782027022","url":"https:\/\/voomisupply.com\/products\/bk-521-975bg-black-iron-hex-bushing-1-1-2-x-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
