Fitted with female NPT (FNPT) threads on both ends, this coupling connects two threaded pipe sections of the same nominal diameter. The 3-inch nominal size makes it suitable for moderate-to-high-flow distribution lines. Schedule 80 PVC wall thickness provides greater pressure tolerance than Schedule 40, making it a common choice where mechanical strength and chemical resistance are both required. Domestic manufacturing is noted by the supplier.\u003c\/p\u003e\u003cp\u003eThis coupling is used in plumbing, irrigation, industrial process piping, and chemical handling systems where PVC is the specified material. It is a standard threaded fitting appropriate for above-ground and in-wall applications wherever FNPT connections are called for. Licensed plumbers and pipefitters are the typical installers of this fitting class in commercial and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSchedule 80 PVC construction for increased wall thickness and pressure rating over Schedule 40\u003c\/li\u003e\n\u003cli\u003eFemale NPT (FNPT) threaded ends for standard threaded pipe connections\u003c\/li\u003e\n\u003cli\u003e3-inch nominal size suitable for moderate-to-high-flow piping runs\u003c\/li\u003e\n\u003cli\u003ePVC material offers corrosion resistance and chemical compatibility across a wide range of fluids\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for Schedule 80 PVC threaded piping systems using 3-inch nominal FNPT connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Always depressurize and drain the system before removing or installing any threaded fitting. Apply thread sealant tape or compound rated for PVC and the specific fluid being conveyed. Do not over-tighten threaded PVC fittings, as excessive torque can crack the fitting body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: SCH 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 808-030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURA PLASTIC","offers":[{"title":"Default Title","offer_id":51523571646770,"sku":"PV80808-030","price":110.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df050a9a2555ee5e56a5ea5a3b59ee1f.jpg?v=1785442831","url":"https:\/\/voomisupply.com\/products\/dura-plastic-808-030-sch-80-pvc-coupling-3-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
