A close nipple has no exposed center unthreaded section — the threads on each end meet or nearly meet at the midpoint, making it the shortest possible nipple for a given pipe size. This configuration is used where minimal fitting-to-fitting distance is required. The Schedule 40 wall thickness provides standard pressure ratings for water, gas, and steam service. Hot-dip galvanizing delivers corrosion resistance for wet or outdoor installations. Licensed plumbers and pipefitters are the primary installers.\u003c\/p\u003e\u003cp\u003eThis nipple is suited for residential and light commercial piping systems where a 3-inch threaded connection must be made with the tightest possible inline spacing. Common applications include water supply mains, boiler piping, gas distribution headers, and pool or spa equipment plumbing where NPT threaded fittings are used throughout. The close configuration is also frequently used to extend a valve or coupling directly from a threaded port without adding measurable pipe length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClose-pattern configuration — minimal center-to-center length between fittings\u003c\/li\u003e\n\u003cli\u003eSchedule 40 wall thickness for standard-service pressure ratings\u003c\/li\u003e\n\u003cli\u003eHot-dip galvanized carbon steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eNPT threaded ends for compatibility with standard threaded fittings and valves\u003c\/li\u003e\n\u003cli\u003eSuitable for water, gas, and steam service in threaded piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 3-inch NPT threaded piping systems using Schedule 40 galvanized steel pipe and fittings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service type. Apply thread sealant tape or pipe dope rated for the intended service — gas, water, or steam — before threading into fittings. Use a pipe wrench on the fitting body, not the nipple center, to avoid deforming the threads. Shut off and depressurize the system completely before removing or installing any threaded components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePattern\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 675135120901\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AQUALINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GPN-30-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AQUALINE","offers":[{"title":"Default Title","offer_id":51396436984114,"sku":"GPN-30-C","price":25.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834181.jpg?v=1782831962","url":"https:\/\/voomisupply.com\/products\/aqualine-gpn-30-c-galvanized-steel-pipe-nipple-3-in-close-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
