This nipple measures 18 inches overall length with 3\/4 inch NPT threads on both ends, making it suitable for extending runs or connecting fittings across moderate distances. The red brass construction offers reliable corrosion resistance in both water and moderate chemical service environments. Weighing 1.65 pounds, this fitting is a straightforward drop-in component for threaded piping assemblies and is handled by licensed plumbers and pipefitters during rough-in or retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis nipple fits into residential and commercial piping systems where a full-length 18 inch threaded connection is required between fittings, valves, or equipment. Common installations include water supply lines, boiler piping, compressed air distribution, gas supply headers, and general process piping. The 3\/4 inch NPT thread standard ensures compatibility with the widest range of standard pipe fittings, valves, and couplings used across the trade. OSHA compliance is noted for installations subject to workplace safety standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRed brass construction provides corrosion resistance for water, gas, and mild chemical service\u003c\/li\u003e\n  \u003cli\u003e18 inches overall length bridges gaps in threaded piping runs without additional fittings\u003c\/li\u003e\n  \u003cli\u003eThreaded on both ends with 3\/4 inch NPT for universal fitment with standard trade fittings\u003c\/li\u003e\n  \u003cli\u003eOSHA-compliant for use in commercial and industrial piping installations\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch outside diameter matches standard iron pipe size for seamless integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-construction fitting for any threaded piping system using 3\/4 inch NPT connections, including water supply, gas, compressed air, and hydronic heating assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and the International Plumbing Code (IPC) or applicable fuel gas codes. Always shut off the water or gas supply and relieve system pressure before removing or installing threaded nipples. Apply an appropriate thread sealant or PTFE tape to the NPT threads prior to assembly, and tighten with pipe wrenches to achieve a leak-free joint. Do not over-tighten, as this can crack fittings or damage threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Red Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIron Pipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Threaded on Both Ends\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: OSHA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.65 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40173300\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2112-1800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538924699954,"sku":"2112-1800","price":84.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50ad58718c661f0c4d531df8aef49bf5.jpg?v=1785829813","url":"https:\/\/voomisupply.com\/products\/merit-brass-2112-1800-brass-pipe-nipple-3-4-npt-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
