Cast from black cast iron and rated at 125 lb, this bushing is a standard fitting used in low-pressure gas, water, and general plumbing piping systems. The hex head profile allows a wrench to seat squarely on the fitting during installation, reducing the risk of rounding or slipping. This is a domestic-made fitting, which is relevant on jobs with domestic-content requirements.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used wherever a pipe reducer is needed between 1-1\/2 inch and 1 inch threaded pipe connections. Typical applications include residential and light commercial plumbing, gas distribution piping, steam lines, and mechanical room header drops. The MNPT x FNPT configuration makes it a direct thread-in reducer — the male end threads into a larger fitting or valve, and the smaller female end accepts the continuation pipe or fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHex head design accepts standard pipe wrench or open-end wrench for positive torque\u003c\/li\u003e\n  \u003cli\u003eMNPT x FNPT end style provides straightforward threaded reducer connection\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure class rated cast iron construction\u003c\/li\u003e\n  \u003cli\u003eBlack cast iron finish standard for gas and general plumbing service\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture for projects with buy-American or domestic-content specifications\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 125 lb cast iron threaded piping systems using standard NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service type. Shut off and depressurize the line before threading in the bushing. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly. Hand-tighten first, then wrench-tighten to achieve a leak-free joint — avoid over-tightening cast iron fittings, which can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: MNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 125 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: ASC Engineered Solutions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1DX1.BB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51524447469874,"sku":"BLBUSH1121","price":15.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae2ba6f05e6c74d0e105bbbe4522590f_968d8148-b077-4355-a656-2de68ee1f343.jpg?v=1785449376","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-1dx1-bb-hex-head-pipe-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
