The flange uses a socket connection and is manufactured from PVC in gray, making it a reliable choice for corrosion-resistant piping applications. It carries a 150 lb pressure class rating and is compatible with SCH 40, STD, SCH 80, and XH pipe schedules. The outside diameter measures 19 inches with a 17-inch bolt circle diameter. This fitting is domestically produced and is installed by licensed plumbers and pipefitters working on industrial, commercial, and municipal water or chemical distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis flange is suited for use in above-ground and accessible underground PVC piping systems where a removable, leak-tight flange connection is required. The Van Stone two-piece design allows the ring to rotate freely before tightening, which simplifies bolt-hole alignment during installation. It is commonly found in water treatment facilities, irrigation systems, chemical processing lines, and pool or spa plumbing where non-metallic corrosion-resistant fittings are specified. The rated operating temperature is 73 degrees F at full pressure, which is standard for PVC pressure fittings in cold-water service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-piece Van Stone design with a rotating glass-filled PVC ring for easy bolt-hole alignment\u003c\/li\u003e\n  \u003cli\u003e12-inch nominal size with a 19-inch outside diameter and 17-inch bolt circle diameter\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating at 73 degrees F with a 150 lb pressure class\u003c\/li\u003e\n  \u003cli\u003eSocket connection compatible with SCH 40, STD, SCH 80, and XH pipe schedules\u003c\/li\u003e\n  \u003cli\u003ePVC construction in gray provides corrosion resistance without metallic components\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured for consistent quality and material compliance\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 12-inch PVC piping systems rated to SCH 40, STD, SCH 80, and XH schedules in 150 lb flange service.\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 applicable IPC and local plumbing codes. Depressurize and drain the line completely before cutting in or replacing any flange. Solvent-cement the socket end per ASTM D2564 procedures, allowing full cure time before pressurizing. Do not exceed the rated pressure or temperature limits marked for this fitting, as PVC pressure ratings decrease significantly above 73 degrees F.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 73 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule Rating\u003c\/strong\u003e: SCH 40 \/ STD \/ SCH 80 \/ XH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Socket\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\u003eCountry of Origin\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: 856-120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPEARS","offers":[{"title":"Default Title","offer_id":51233978548530,"sku":"856-120","price":210.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/856-120.jpg?v=1780113819","url":"https:\/\/voomisupply.com\/products\/spears-856-120-van-stone-molded-flange-12-in-socket-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
