It measures 5.5 inches in length with a 1.25-inch outside diameter and carries male pipe thread (MPT) connections on both ends, cut to the ANSI\/ASME B1.20.1 standard thread form at 1-1\/4-11-1\/2. The Schedule 80 wall thickness supports a working pressure rating of 3000 psi, making it suitable for demanding fluid and gas systems. Plumbers, pipefitters, and industrial maintenance technicians install this nipple when joining threaded pipe sections in close-coupled or extension configurations across air, water, oil, natural gas, and steam service lines.\u003c\/p\u003e\u003cp\u003eThis nipple is designed for both commercial and industrial piping systems where corrosion resistance and pressure integrity are required. Typical applications include steam distribution headers, compressed air manifolds, natural gas supply piping, hydraulic oil lines, and potable or process water systems. Its seamless construction eliminates weld seams that can introduce stress concentrations, which is especially relevant in high-cycle or high-temperature environments. The 304 stainless steel base material resists oxidation and general corrosion across a wide range of service media.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSeamless 304 stainless steel construction resists corrosion in air, water, oil, natural gas, and steam service\u003c\/li\u003e\n\u003cli\u003eSchedule 80 wall rating supports 3000 psi working pressure\u003c\/li\u003e\n\u003cli\u003e1-1\/4-11-1\/2 NPT thread form manufactured to ANSI\/ASME B1.20.1 dimensional standards\u003c\/li\u003e\n\u003cli\u003eMale pipe thread on both ends for direct threaded pipe or fitting connections\u003c\/li\u003e\n\u003cli\u003e5.5-inch body length suits close-nipple extensions and offset installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with air, water, oil, natural gas, and steam service.

Isolate and depressurize the line and allow it to cool before removing or threading any fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium to the male threads before assembly. Do not use pipe wrenches on the fitting body in a way that could deform the seating surfaces, and do not overtighten, as stainless steel threads are susceptible to galling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MPT x MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1-1\/4-11-1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule Rating\u003c\/strong\u003e: SCH 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Seamless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ANSI\/ASME B1.20.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Air, Water, Oil, Natural Gas, Steam\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948590760242,"sku":"51128","price":90.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1196f18aa9ee00ed93ad20fe997e181.jpg?v=1791668446","url":"https:\/\/voomisupply.com\/products\/midland-industries-51128-pipe-nipple-1-1-4-in-sch-80-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
