It bridges the gap between dissimilar pipe materials and reduces from a 4-inch pipe to a 2-inch pipe in a single fitting. The elastomeric PVC body compresses around the pipe ends for a watertight seal, while the included 300-series stainless-steel clamps resist rust and corrosion. The additional band slots built into the clamp design allow for enhanced flexibility during installation. Licensed plumbers and pipefitters install this fitting during new construction, remodels, and repair work where rigid couplings are impractical.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial DWV applications where a flexible, underground-rated connection is required. It accommodates cast-iron, plastic, copper, steel, and lead pipe materials, making it a practical solution for retrofit and repair jobs involving older pipe materials alongside modern plastic pipe. The reducer profile is common in stack, branch, and drain line connections where pipe sizes change between floors or fixture groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 4-inch pipe to 2-inch pipe in a single flexible coupling\u003c\/li\u003e\n  \u003cli\u003eElastomeric PVC body rated for underground installation\u003c\/li\u003e\n  \u003cli\u003e300-series stainless-steel clamps resist rust and corrosion\u003c\/li\u003e\n  \u003cli\u003eAdditional band slots on clamps provide enhanced installation flexibility\u003c\/li\u003e\n  \u003cli\u003eCompatible with cast-iron, plastic, copper, steel, and lead pipe materials\u003c\/li\u003e\n  \u003cli\u003eSold in a case pack of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to connect cast-iron, plastic, copper, steel, and lead DWV pipe in 4-inch to 2-inch reducer configurations.

Shut off water flow and relieve any pressure in the line before cutting into an existing drain or waste stack. Pipe ends should be clean, deburred, and free of sharp edges before sliding the coupling into position. Tighten stainless-steel clamp bands evenly to the manufacturer-specified torque range using a nut driver or clamp tool — do not overtighten, as this can deform the elastomeric sleeve.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Flexible PVC (elastomeric)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Material\u003c\/strong\u003e: 300-series stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV (Drain, Waste, Vent)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnderground Rated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Pack\u003c\/strong\u003e: 10 units\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1056-42\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138323480882,"sku":"1056-42","price":33.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305525554.jpg?v=1778253394","url":"https:\/\/voomisupply.com\/products\/fernco-1056-42-flexible-pvc-dwv-coupling-4x2","provider":"Voomi Supply","version":"1.0","type":"link"}
