It includes a loose ring that allows the flange bolt holes to rotate freely, making bolt-hole alignment straightforward during installation. Schedule 80 PVC provides thicker walls and higher pressure ratings than Schedule 40, making it suitable for demanding plumbing and industrial piping applications. Licensed plumbers and pipefitters install this fitting where a removable, rotatable flange connection is required in a corrosion-resistant thermoplastic system.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and commercial plumbing, irrigation, chemical transfer, and water treatment piping systems where PVC Schedule 80 pipe is specified. The Van Stone design keeps the loose ring on the outside of the stub end, so only the PVC contacts the process fluid. This makes it a practical choice for installations where metal contamination must be avoided or where frequent disassembly is expected. The slip socket end accepts standard 4-inch Schedule 80 PVC pipe for solvent-cement joining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal size slip socket connection for Schedule 80 PVC pipe\u003c\/li\u003e\n  \u003cli\u003eVan Stone design with a rotatable loose ring for easy bolt-hole alignment\u003c\/li\u003e\n  \u003cli\u003eSchedule 80 wall thickness for higher pressure service compared to Schedule 40\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists corrosion, chemicals, and scale buildup\u003c\/li\u003e\n  \u003cli\u003eLoose ring floats freely so only PVC contacts the process fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 4-inch Schedule 80 PVC piping systems using solvent-cement slip socket connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Depressurize and drain the piping system completely before cutting into an existing line. Use approved PVC Schedule 80 solvent cement and primer on the slip socket end per the cement manufacturer and ASTM D2564 guidelines. Do not over-torque the flange bolts against the loose ring, as PVC flanges require even, hand-snug torque patterns to avoid cracking the stub end face.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Slip Socket (solvent cement)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Style\u003c\/strong\u003e: Van Stone with Loose Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: Schedule 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC (Polyvinyl Chloride)\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: PVC80FLGVSS4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURA PLASTIC","offers":[{"title":"Default Title","offer_id":51524682711346,"sku":"80FLGVSS4","price":73.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6fea91e58499215a76c6bc5cbbc41cd.jpg?v=1785455122","url":"https:\/\/voomisupply.com\/products\/dura-plastic-pvc80flgvss4-pvc-sch-80-van-stone-flange-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
