Manufactured from ASTM A53 welded steel pipe and dimensioned to ASTM A733, this nipple is built for reliable performance in gas, water, and general plumbing distribution systems. The black finish suits standard interior applications where galvanized or electroplated coatings are not required. Licensed plumbers and pipefitters install this fitting in both residential and light commercial piping assemblies.\u003c\/p\u003e\n\u003cp\u003eThis nipple is suited for use in residential and commercial piping systems where a short close nipple connection is needed between threaded fittings, valves, or equipment. Common applications include natural gas distribution, steam lines, water supply, and general-purpose pipe runs. The 2.5-inch nominal pipe diameter and 3.5-inch overall length make it a practical choice for tight-space installations within mechanical rooms, utility chases, and equipment hookups requiring a compact threaded connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eManufactured from ASTM A53 welded steel pipe for consistent wall thickness and strength\u003c\/li\u003e\n  \u003cli\u003eDimensions conform to ASTM A733 standard nipple specifications\u003c\/li\u003e\n  \u003cli\u003eNPT threads per ASME B1.20.1 ensure leak-resistant, compatible connections with standard fittings\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for gas and general-purpose plumbing applications\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture supporting quality traceability for commercial and industrial jobs\u003c\/li\u003e\n  \u003cli\u003eAvailable in Standard and Extra Heavy wall configurations in the broader product family\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded steel piping systems using 2.5-inch nominal NPT connections in residential and commercial mechanical applications.\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 applicable local codes and the International Plumbing Code or International Fuel Gas Code where relevant. Shut off and depressurize the line completely before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape to male threads before makeup. Do not over-tighten threaded connections, as this can damage threads or cause cracking in mating fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: ASTM A53 Welded Steel Pipe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ASTM A733\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT per ASME B1.20.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: 339\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: NIPPLES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 330041609\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIPPLES","offers":[{"title":"Default Title","offer_id":51150757200178,"sku":"0330041609","price":44.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986515.jpg?v=1778617797","url":"https:\/\/voomisupply.com\/products\/nipples-330041609-black-steel-pipe-nipple-2-5x3-5-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
