Sized at 1-1\/4 inches, it provides a reliable, pressure-rated mechanical seal in drainage, chemical, and industrial fluid systems where corrosion resistance is essential. The black polypropylene construction offers strong resistance to a wide range of chemicals, making it suitable for demanding service environments. Licensed plumbers and pipefitters install this fitting as part of pipe pressure testing, system capping, or permanent line termination. Its hex-head profile allows for wrench tightening to achieve a secure, leak-free seal on threaded connections.\u003c\/p\u003e\u003cp\u003eThis hex plug is intended for use in Schedule 80 plastic piping systems where MPT end connections are required. It is commonly installed in residential and light commercial plumbing, industrial chemical distribution lines, and process piping. The 1-1\/4 inch size fits standard NPT-threaded outlets on Schedule 80 pipe and fittings. It is well-suited for applications requiring corrosion resistance or where metal fittings would be inappropriate due to chemical exposure or galvanic concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSchedule 80 pressure rating for use in demanding piping applications\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction provides resistance to corrosion and many chemicals\u003c\/li\u003e\n\u003cli\u003eMPT end connection allows wrench-tightened installation onto female-threaded fittings or pipe ends\u003c\/li\u003e\n\u003cli\u003eHex head profile enables standard wrench or socket installation\u003c\/li\u003e\n\u003cli\u003eBlack color consistent with Schedule 80 plastic fitting standards\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.18 pounds — easy to handle and stock\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 plastic piping systems using 1-1\/4 inch NPT threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is installed by licensed plumbers or pipefitters working on plastic piping systems. Depressurize and drain the line before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation; do not overtighten, as polypropylene threads can crack under excessive torque. Installation should conform to applicable local plumbing codes and ASTM standards for thermoplastic piping systems.\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: 1-1\/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: MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: CC03700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539206406450,"sku":"CC03700","price":72.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3ff0c02ce3d574163b97a3989b9efbc.jpg?v=1785836569","url":"https:\/\/voomisupply.com\/products\/nibco-cc03700-hex-plug-1-1-4-in-polypropylene-schedule-80-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
