Constructed from CPVC and rated to 150 psi at 73 degrees F, this flange accepts a 3\/4 inch FNPT connection and is built to Schedule 80\/XH standards. The van stone design allows the plastic ring to rotate freely, making bolt-hole alignment straightforward during installation. With an outside diameter of 3-7\/8 inches and a bolt circle diameter of 2-3\/4 inches, it is dimensioned for standard 150 lb flange mating. Licensed plumbers and pipefitters working in chemical handling, industrial, or corrosive-fluid systems specify CPVC flanges where metal fittings are unsuitable.\u003c\/p\u003e\n\u003cp\u003eThis flange is suited for residential and light commercial pressure piping applications where CPVC is the system material of choice. It is commonly installed in chemical distribution lines, water treatment systems, and process piping where corrosion resistance is a priority. The FNPT end allows direct threaded connection to Schedule 80 CPVC pipe or fittings. Its gray color is consistent with standard CPVC Schedule 80 system components, making it easy to integrate into existing installations. Domestic manufacture supports traceability requirements on projects where country-of-origin documentation is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-piece van stone design with rotating plastic ring for easy bolt-hole alignment\u003c\/li\u003e\n  \u003cli\u003eCPVC construction rated for corrosive-fluid and chemical piping service\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating at 73 degrees F\u003c\/li\u003e\n  \u003cli\u003eSchedule 80\/XH rating compatible with heavy-wall CPVC piping systems\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch FNPT connection for direct threaded assembly\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured for traceability and consistent material quality\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 80 CPVC pressure piping systems using 3\/4 inch FNPT-connected components rated at 150 lb class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter familiar with thermoplastic pressure piping. Depressurize and drain the system completely before making any flange connections. Use appropriate CPVC-compatible thread sealant on FNPT threads and do not overtighten, as CPVC is susceptible to stress cracking from excessive torque. Follow applicable plumbing codes, including IPC and local amendments, for flange joint assembly and pressure testing requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT\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 80\/XH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: CPVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Pressure\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: 855-007c\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPEARS","offers":[{"title":"Default Title","offer_id":51234035433778,"sku":"855-007C","price":43.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cpvcthrdflg.jpg?v=1780115761","url":"https:\/\/voomisupply.com\/products\/spears-855-007c-van-stone-flange-3-4-in-cpvc-fnpt-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
