This coupling provides a reliable mechanical joint that accommodates standard outside-diameter differences between pipe types, making it a go-to solution for water and wastewater distribution repairs and installations. Licensed plumbers and water system contractors install this type of fitting when transitioning between pipe materials such as cast iron, ductile iron, PVC, or concrete in underground or above-grade applications.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for municipal water distribution, sewer systems, and industrial piping applications where a 3-inch nominal pipe size connection spanning 10 inches of coupling length is required. The Series 501 design is commonly used in both new construction and retrofit work where pipe material transitions occur at service connections, mains repairs, or lateral installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron construction for durability in buried and exposed piping environments\u003c\/li\u003e\n  \u003cli\u003eSeries 501 transition coupling design accommodates differing pipe outside diameters\u003c\/li\u003e\n  \u003cli\u003e3-inch nominal pipe size with 10-inch coupling length\u003c\/li\u003e\n  \u003cli\u003eSuitable for pressure and non-pressure piping system applications\u003c\/li\u003e\n  \u003cli\u003eMechanical joint connection eliminates need for welding or special tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style transition coupling for 3-inch nominal diameter piping systems where material transitions are required in water, wastewater, or industrial distribution applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or certified water system contractor in accordance with local plumbing codes and applicable AWWA standards. Shut off and depressurize the line before beginning work and confirm pipe outside diameters are within the coupling range prior to assembly. Bolts should be tightened evenly in a cross pattern to ensure uniform gasket compression. Follow the manufacturer torque sequence guidelines provided with the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 501\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: ROMAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 201-03510351000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROMAC","offers":[{"title":"Default Title","offer_id":51233269940530,"sku":"201-03510351000","price":294.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307626889.jpg?v=1780095810","url":"https:\/\/voomisupply.com\/products\/romac-201-03510351000-cast-iron-transition-coupling-3x10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
