It connects a 2-inch pipe to a 1-1\/2-inch pipe using a hub-by-hub end connection, making it a straightforward choice for reducing transitions in gravity-flow drainage lines. Constructed from PVC conforming to ASTM D2665, F1498, D331, and D1784, the fitting delivers strong chemical resistance and corrosion resistance. Smooth interior walls minimize scaling and support unrestricted flow. Licensed plumbers and plumbing contractors install this fitting in both new construction and retrofit drain line applications.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial DWV applications where a pipe size reduction from 2 inches to 1-1\/2 inches is required. Typical installations include branch line transitions, fixture drain connections, and horizontal drain runs where flow direction and gravity drainage must be maintained. Its chemical resistance also makes it appropriate for select chemical drainage applications where PVC is a compatible material. The fitting meets NSF 14 and UPC standards, supporting code-compliant installations in jurisdictions that adopt those criteria.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing hub-by-hub configuration transitions 2-inch pipe to 1-1\/2-inch pipe\u003c\/li\u003e\n  \u003cli\u003ePVC construction provides resistance to chemicals and corrosion\u003c\/li\u003e\n  \u003cli\u003eSmooth interior walls reduce scaling and support free-flow drainage\u003c\/li\u003e\n  \u003cli\u003eMeets NSF 14 and UPC standards for code-compliant DWV installations\u003c\/li\u003e\n  \u003cli\u003eConforms to ASTM D2665, F1498, D331, and D1784 material and dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for PVC DWV piping systems requiring a 2-inch to 1-1\/2-inch hub reducing coupling.

Shut off the water supply and ensure the drain line is fully depressurized and drained before cutting into an existing system. Use PVC primer and solvent cement rated for DWV applications and allow full cure time before returning the line to service. Do not apply mechanical force or torque to the fitting during the cure period.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Pipe Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Hub x Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: ASTM D2665, F1498, D331, D1784\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV, Chemical, Corrosion-Resistant Drainage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: NSF 14, UPC\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5948\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51467319574834,"sku":"5948","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946341.jpg?v=1783901322","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-5948-pvc-dwv-hub-coupling-reducer","provider":"Voomi Supply","version":"1.0","type":"link"}
