It connects a socket end to a female NPT threaded port, allowing a smooth transition between solvent-welded PVC pipe and threaded fittings. Molded from gray PVC, this adapter meets the dimensional and pressure requirements of Schedule 80 Extra Heavy service. At 3-31\/32 inches in length, it fits standard 4-inch nominal pipe and is manufactured domestically. Licensed plumbers and pipefitters install this fitting in industrial, commercial, and municipal water systems where Schedule 80 pressure ratings are specified.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in pressure piping applications requiring a durable, corrosion-resistant connection between PVC socket pipe and female-threaded components. Common installations include process water lines, irrigation mains, chemical distribution headers, and commercial plumbing systems. The socket end accepts standard 4-inch PVC pipe for solvent cement joining, while the FNPT end receives a male-threaded valve, pump port, or equipment connection. Schedule 80 ratings make it suitable for higher-pressure service lines where standard Schedule 40 fittings are insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal size with Socket x FNPT end configuration\u003c\/li\u003e\n  \u003cli\u003eSchedule 80 Extra Heavy pressure rating for demanding service conditions\u003c\/li\u003e\n  \u003cli\u003eMolded PVC construction provides chemical and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3-31\/32 inch overall length fits standard 4-inch nominal pipe systems\u003c\/li\u003e\n  \u003cli\u003eGray color consistent with Schedule 80 PVC system identification\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured to support quality control standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-service fitting for 4-inch Schedule 80 PVC pressure piping systems using solvent-welded socket connections and female NPT threaded ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and ASTM standards for PVC pressure piping. Depressurize and drain the line completely before cutting or joining. Use only approved PVC primer and solvent cement on the socket end, and allow full cure time before restoring pressure. Do not over-torque threaded connections on the FNPT end, as PVC threads are susceptible to cracking under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Socket x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule Rating\u003c\/strong\u003e: Schedule 80 Extra Heavy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Female Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: Pressure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMethod of Manufacture\u003c\/strong\u003e: Molded\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: SPEARS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54211155400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPEARS","offers":[{"title":"Default Title","offer_id":51267963978034,"sku":"54211155400","price":77.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/Approved_Vendor_P127272_12e4d339-fdec-442c-bcff-a3c442a40815.jpg?v=1780695681","url":"https:\/\/voomisupply.com\/products\/spears-54211155400-pvc-female-adapter-4-in-socket-x-fnpt-sch-80","provider":"Voomi Supply","version":"1.0","type":"link"}
