It features female pipe thread (FPT) connections on both ends, allowing it to couple two male-threaded pipe ends or fittings in a single assembly. The Schedule 80 wall thickness provides greater pressure capacity compared to Schedule 40, making it suitable for demanding service conditions. Polypropylene construction offers solid resistance to a wide range of chemicals and corrosive media. Plumbers and pipefitters install this fitting in both new construction and retrofit applications where a compact, threaded plastic coupling is required.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial plumbing, industrial piping, and chemical handling systems where polypropylene material compatibility is required. The 3\/4-inch FPT x FPT configuration makes it a straightforward solution for connecting threaded pipe runs or transitioning between threaded plastic components in systems that demand Schedule 80 ratings. It is sold individually and installed in systems requiring reliable, leak-free threaded connections in corrosive or high-purity fluid service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSchedule 80 polypropylene construction for enhanced wall thickness and higher pressure ratings versus Schedule 40\u003c\/li\u003e\n\u003cli\u003eFPT x FPT end connections accept standard male-threaded pipe or fittings on both sides\u003c\/li\u003e\n\u003cli\u003e3\/4-inch fitting size fits standard 3\/4-inch threaded pipe systems\u003c\/li\u003e\n\u003cli\u003ePolypropylene material provides broad chemical resistance for industrial and corrosive service\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.08 pounds, reducing load in overhead or vertical piping runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install fitting for 3\/4-inch Schedule 80 polypropylene threaded piping systems using standard FPT connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply PTFE thread tape or an approved thread sealant rated for polypropylene and the service fluid before threading the fitting onto male pipe ends. Do not overtighten polypropylene fittings, as the material can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Adapter Coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FPT x FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CN00550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51544495292722,"sku":"CN00550","price":58.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1359a6d19971c48d582a65407f63de1e_af36b32b-5be6-49a9-9a9c-c835156800d1.jpg?v=1785928071","url":"https:\/\/voomisupply.com\/products\/nibco-cn00550-3-4-in-poly-adapter-coupling-sch-80-fpt","provider":"Voomi Supply","version":"1.0","type":"link"}
