NPT (National Pipe Taper) taps produce the tapered thread form required for pressure-tight connections in plumbing, HVAC piping, and gas distribution systems. This tap is sold as a single unit and is sized for 1-1\/4-inch nominal pipe thread applications. It is a hand or machine tap used by plumbers, pipefitters, and mechanical contractors when threading new ports or chasing damaged internal threads in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe IR1908ZR is suited for maintenance, repair, and fabrication work on residential and commercial piping systems. Common applications include threading pipe flanges, manifold blocks, pump housings, and valve bodies that require a 1-1\/4-inch NPT internal thread. It is appropriate for use in plumbing rough-in, HVAC hydronic piping, and industrial pipe fabrication where NPT thread standards apply.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-inch NPT tapered pipe thread form for pressure-rated connections\u003c\/li\u003e\n\u003cli\u003eSized for nominal 1-1\/4-inch pipe thread applications\u003c\/li\u003e\n\u003cli\u003eSuitable for hand tapping or machine tapping operations\u003c\/li\u003e\n\u003cli\u003eAppropriate for use on ferrous and non-ferrous base materials\u003c\/li\u003e\n\u003cli\u003eSold individually — one tap per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement tap for 1-1\/4-inch NPT internal threading applications in standard pipe fittings and ported components conforming to NPT thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePipe taps of this size should be installed by licensed plumbers or pipefitters familiar with NPT thread standards and proper tapping procedures. Use the correct tap drill size for a 1-1\/4-inch NPT thread before tapping, and apply cutting fluid throughout the operation to extend tap life and produce clean thread form. Always secure the workpiece firmly before tapping. Follow applicable code requirements, including IPC or IFGC provisions, when threading components for gas or pressurized fluid service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 042526019081\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR1908ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346920767794,"sku":"IR1908ZR","price":99.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499489.jpg?v=1782094629","url":"https:\/\/voomisupply.com\/products\/irwin-ir1908zr-npt-pipe-tap-1-1-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
