It connects cast iron, plastic, or steel pipe to 4-inch copper pipe using a flexible elastomeric sleeve secured by a stainless steel shield and band clamps. The shielded design provides superior resistance to heavy earth loads and shear forces compared to standard flexible couplings. Plumbers and drain contractors install this fitting where soil movement, backfill pressure, or pipe misalignment is a concern. The coupling weighs 16.8 pounds per package unit and is sold individually.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and commercial underground or in-wall plumbing transitions where cast iron meets copper, plastic meets copper, or steel meets copper at 4-inch nominal pipe diameter. Typical applications include sewer lateral repairs, building drain tie-ins, and service upgrades where existing cast iron drain lines are extended with copper or plastic pipe. The Proflex shielded series is engineered specifically for high-stress burial environments where standard no-hub couplings may not provide sufficient mechanical strength.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConnects cast iron, plastic, or steel pipe to 4-inch copper pipe\u003c\/li\u003e\n  \u003cli\u003eShielded construction resists heavy earth loads and shear forces\u003c\/li\u003e\n  \u003cli\u003eImproves pipe alignment at dissimilar-material transitions\u003c\/li\u003e\n  \u003cli\u003eStainless steel shield and band clamps provide a secure, leak-resistant connection\u003c\/li\u003e\n  \u003cli\u003eFlexible elastomeric sleeve accommodates minor angular misalignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 4-inch nominal pipe transitions involving cast iron, plastic, or steel pipe connecting to 4-inch copper pipe.

Shut off flow and relieve any system pressure before cutting into an existing line. Pipe ends should be clean, deburred, and free of debris before seating the elastomeric sleeve. Do not overtighten band clamps beyond the manufacturer torque specification listed on the coupling packaging.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Materials\u003c\/strong\u003e: Cast iron, plastic, steel to copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 16.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24\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: FERNCO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P3001-44\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51525004329266,"sku":"P3001-44","price":439.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d43778fdca68e74c30267ce4f6f851d0.jpg?v=1785462648","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p3001-44-shielded-coupling-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
