Manufactured from black polypropylene, this hex plug offers solid chemical resistance and durability in demanding fluid-handling applications. The male NPT (MNPT) thread connection conforms to standard pipe thread dimensions, allowing straightforward installation into female-threaded fittings, valves, or pipe ends. At 0.66 pounds, the fitting is lightweight yet rated for the pressure demands of Schedule 80 service. Licensed plumbers and pipefitters are the primary installers of this component in process piping, chemical handling, and water distribution systems.\u003c\/p\u003e\u003cp\u003eThis hex plug is suited for residential, commercial, and light industrial applications where a threaded pipe end must be sealed or capped. Common install scenarios include system commissioning, pressure testing, and permanent pipe-end closure in Schedule 80 thermoplastic piping systems. The black polypropylene construction makes it appropriate for environments where corrosion resistance or chemical compatibility is a requirement, such as chemical processing lines, irrigation manifolds, and plumbing drain or vent systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch fitting size with male NPT (MNPT) end connection for standard threaded pipe compatibility\u003c\/li\u003e\n\u003cli\u003eSchedule 80 rating for higher-pressure service compared to Schedule 40 fittings\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction provides resistance to a broad range of chemicals and corrosive fluids\u003c\/li\u003e\n\u003cli\u003eBlack color finish standard for this material and pressure class\u003c\/li\u003e\n\u003cli\u003eHex head design allows installation and removal with a standard pipe wrench or adjustable wrench\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.66 pounds, reducing load on threaded connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for Schedule 80 thermoplastic piping systems using standard male NPT threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Isolate and depressurize the system completely before threading any fitting into a live line. Apply a compatible thread sealant or PTFE tape to the male threads before installation, following the pipe manufacturer recommendations and applicable IPC or local plumbing code requirements. Do not overtighten polypropylene fittings, as excessive torque can crack the material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.66 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: CC03900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539186680114,"sku":"CC03900","price":167.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f77b79e6b952f72dc704a6388f73d35.jpg?v=1785836157","url":"https:\/\/voomisupply.com\/products\/nibco-cc03900-4-in-poly-schedule-80-hex-plug-male-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
