Built under the Proflex Specialty Coupling line, it connects cast iron, plastic, or steel pipe to 3-inch copper pipe. The shielded construction adds structural reinforcement that resists heavy earth loads and shear forces, making it suitable for buried or in-slab installations where standard couplings may not hold up. Licensed plumbers and pipefitters typically install this fitting during new construction or repair work on drain, waste, and vent systems.\u003c\/p\u003e\u003cp\u003eThis coupling is used in residential and light commercial plumbing applications where pipes of different materials meet at a transition point. It is particularly well-suited for underground or below-slab drain line repairs where soil movement, settlement, or shear stress can place lateral force on pipe joints. The design also improves pipe alignment at the connection, reducing stress concentrations that can lead to joint failure over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConnects cast iron, plastic, or steel pipe to 3-inch copper pipe\u003c\/li\u003e\n\u003cli\u003eShielded design resists heavy earth loads and shear forces\u003c\/li\u003e\n\u003cli\u003eImproves pipe alignment at the transition joint\u003c\/li\u003e\n\u003cli\u003eSuitable for buried and below-slab installations\u003c\/li\u003e\n\u003cli\u003eProflex Specialty Coupling construction for demanding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for transitions between cast iron, plastic, or steel pipe and 3-inch copper pipe in drain, waste, and vent plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water flow and relieve any system pressure before cutting into an existing drain line. Ensure pipe ends are clean, free of burrs, and properly aligned before tightening the shielded coupling clamps. Do not overtighten stainless clamps on fragile pipe materials such as older cast iron without inspecting pipe condition first.\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\u003eConnection Types\u003c\/strong\u003e: Cast iron, plastic, or steel to copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24 per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FERNCO INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P3001-33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51523729260850,"sku":"P3001-33","price":417.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/960e2e26be095bba5c40d7a174411547.jpg?v=1785443673","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p3001-33-shielded-coupling-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
