It features a 3-inch spigot end and a 1.5-inch socket end, allowing a direct transition between pipe sizes without additional adapters. PVC construction makes this fitting suitable for cold and ambient-temperature water service, drain and waste lines, and irrigation systems. Licensed plumbers and pipefitters install this type of fitting in both residential and light commercial applications where a permanent, solvent-welded reduction is required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in Schedule 40 PVC piping systems where a 3-inch main line steps down to a 1.5-inch branch or outlet. Typical install scenarios include domestic water distribution, pool and spa plumbing, irrigation mainlines, and drain-waste-vent systems where a reduction in pipe diameter is needed at a junction point. The spigot end slides into a standard 3-inch socket fitting or valve, while the socket end accepts a standard 1.5-inch spigot pipe or fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchedule 40 PVC construction for pressure-rated service in standard plumbing systems\u003c\/li\u003e\n  \u003cli\u003e3-inch spigot x 1.5-inch socket end configuration enables inline pipe size reduction\u003c\/li\u003e\n  \u003cli\u003eSolvent-weld end style provides a permanent, leak-free joint when properly cleaned and primed\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard Schedule 40 PVC pipe and fittings of matching nominal sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for Schedule 40 PVC piping systems using 3-inch and 1.5-inch nominal pipe sizes with solvent-weld connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters following IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before cutting into an existing system. Clean and deburr all pipe ends, apply approved PVC primer, then solvent cement before joining. Allow full cure time per the cement manufacturer instructions before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: SCH 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 inches x 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Spigot x Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: DURA PLASTIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 437-337BC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURA PLASTIC","offers":[{"title":"Default Title","offer_id":51524896063794,"sku":"40BUSHSPS3112","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfe5d01d3a715651e9dbbeb1d809d151.jpg?v=1785460960","url":"https:\/\/voomisupply.com\/products\/dura-plastic-437-337bc-pvc-reducing-coupling-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
