It features a 1-1\/4 inch male NPT connection on one end and a 4-1\/2 inch threaded-both-ends (TBE) configuration, making it a direct fit for standard threaded fittings. Constructed from Grade B welded steel with a galvanized finish, this nipple is rated for service at up to 150 psi at 150 degrees F. It is manufactured in the United States and suited for plumbing, mechanical, and HVAC piping installations.\u003c\/p\u003e\n\u003cp\u003eThis pipe nipple is rated for use with air, gases, non-potable water, and oils, making it appropriate for a wide range of mechanical and industrial piping systems. Typical installation scenarios include branch connections, riser assemblies, and close nipple runs in commercial and residential mechanical rooms. The galvanized finish provides corrosion resistance in exposed or moderately humid environments. Licensed plumbers and pipefitters routinely specify Schedule 40 galvanized nipples for gas distribution and non-potable service lines where threaded connections are required by design or code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchedule 40 wall thickness for standard-pressure threaded piping systems\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish provides corrosion resistance for mechanical and industrial environments\u003c\/li\u003e\n  \u003cli\u003eGrade B welded steel construction meets standard pipe nipple material requirements\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi at 150 degrees F for reliable service in rated applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch MNPT x 4-1\/2 inch TBE configuration for direct thread engagement\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\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 compatible with standard 1-1\/4 inch NPT threaded pipe fittings, couplings, valves, and accessories used in Schedule 40 galvanized piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Shut off the relevant gas, water, or air supply and depressurize the line before making or breaking any threaded connection. Apply an approved thread sealant or PTFE tape to male threads before assembly. Tighten to proper engagement using a pipe wrench, taking care not to over-torque and crack fittings or compromise the galvanized coating at the joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT x TBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 150 psi at 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Welded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air, Gases, Non-Potable Water, Oils\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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: 331029405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIPPLES","offers":[{"title":"Default Title","offer_id":51150674428210,"sku":"0331029405","price":19.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986473.jpg?v=1778615644","url":"https:\/\/voomisupply.com\/products\/nipples-331029405-galvanized-pipe-nipple-1-1-4-in-mnpt-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
