This fitting connects a pipe to a flanged connection point, allowing bolted assembly to pumps, valves, tanks, and other flanged equipment. Made from PVC, it offers solid chemical resistance for water and wastewater service. The Schedule 80 wall thickness makes it suitable for higher-pressure applications compared to Schedule 40 fittings. Licensed plumbers and pipefitters install this type of fitting in both residential and commercial systems where a leak-free, bolted flange joint is required.\u003c\/p\u003e\n\u003cp\u003eThis flange hub is used in PVC Schedule 80 piping systems that require a rigid, pressure-rated transition to flanged equipment. Typical applications include water treatment, irrigation mainlines, pump stations, and industrial fluid handling. The 4-inch size fits standard 4-inch PVC pipe and mates with standard 4-inch ANSI flange bolt patterns. It is suited for above-ground and below-grade installations where PVC is the specified material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchedule 80 PVC construction provides higher pressure rating than Schedule 40\u003c\/li\u003e\n  \u003cli\u003ePressure-rated fitting suitable for pressurized piping systems\u003c\/li\u003e\n  \u003cli\u003e4-inch size fits standard 4-inch PVC pipe\u003c\/li\u003e\n  \u003cli\u003ePVC material delivers corrosion and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eSocket connection end for solvent-cement joining to pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for 4-inch PVC Schedule 80 piping systems requiring a flanged connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber following applicable IPC and local plumbing codes. Shut off and depressurize the system completely before cutting into any existing piping. Use PVC Schedule 80-rated solvent cement and primer on the socket end, following manufacturer dwell and cure time requirements before restoring pressure. Do not subject the assembled joint to pressure testing until full cure is achieved.\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: Schedule 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Flange Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: PVC Fittings\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: LASCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 851-H40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LASCO","offers":[{"title":"Default Title","offer_id":51306847699250,"sku":"851-H40","price":23.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549179.jpg?v=1781300327","url":"https:\/\/voomisupply.com\/products\/lasco-851-h40-pvc-schedule-80-flange-hub-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
