It provides a reliable mechanical connection between pipe sections, joining or repairing lines without welding. This type of coupling is commonly used in water distribution, industrial piping, and mechanical systems where a fast, field-installable joint is required. Licensed plumbers and pipefitters install this fitting as part of new construction or repair work on steel pipe systems.\u003c\/p\u003e\u003cp\u003eThe BAKCOUP3 is suited for 3-inch steel pipe applications in both commercial and industrial settings. Typical use cases include water mains, fire protection piping, and process lines where a leak-resistant, bolted coupling connection is needed. The coupling allows for slight angular deflection and pipe-end irregularities, making it practical for field repairs and tie-in connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for 3-inch nominal steel pipe\u003c\/li\u003e\n\u003cli\u003eStandard coupling configuration for joining or repairing pipe sections\u003c\/li\u003e\n\u003cli\u003eMechanical assembly eliminates field welding\u003c\/li\u003e\n\u003cli\u003eAccommodates minor pipe-end variations common in field conditions\u003c\/li\u003e\n\u003cli\u003eSuitable for water distribution and industrial piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement coupling for standard 3-inch steel pipe systems in commercial and industrial plumbing and piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC. Depressurize and drain the line completely before disassembling any pipe section or installing the coupling. Follow the manufacturer torque sequence for all bolted components to ensure an even, leak-free seal. Do not exceed the rated working pressure for this coupling type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Material Compatibility\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SMITH-BLAIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BAKCOUP3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMITH-BLAIR","offers":[{"title":"Default Title","offer_id":51525237604658,"sku":"COUP3-G","price":250.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75c2d75b03f50ad86dc2d622b89b96ab_fa6051c4-d1ed-4266-aa1c-f75df7155502.jpg?v=1785468092","url":"https:\/\/voomisupply.com\/products\/smith-blair-bakcoup3-standard-coupling-3-in-steel-pipe","provider":"Voomi Supply","version":"1.0","type":"link"}
