NPT (National Pipe Taper) threads form a pressure-seal joint as they are tightened, making this tap a standard tool for plumbing, HVAC, and industrial piping work. Plumbers, pipefitters, and HVAC technicians use this tap to create leak-resistant threaded connections in new installations and repair work. The tapered profile conforms to ANSI NPT thread standards, ensuring proper fit with standard NPT fittings and valves.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 1\/4-inch pipe ports in a range of materials encountered in residential and light commercial trade work, including ferrous and non-ferrous metals. Typical applications include adding or restoring threaded ports on valve bodies, manifolds, pipe caps, and fittings where NPT connections are required. It is a hand-tap-style tool intended for use with a standard tap wrench or adjustable tap holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch NPT tapered thread profile conforms to ANSI NPT standards\u003c\/li\u003e\n\u003cli\u003eCuts internal tapered threads for pressure-seal pipe connections\u003c\/li\u003e\n\u003cli\u003eCompatible with standard tap wrenches and adjustable tap holders\u003c\/li\u003e\n\u003cli\u003eSuitable for use on ferrous and non-ferrous metals common in trade piping work\u003c\/li\u003e\n\u003cli\u003eSold individually (each unit)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting standard 1\/4-inch NPT internal threads in pipe fittings, valve bodies, manifolds, and threaded ports where ANSI NPT pipe thread standards apply.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed plumber, pipefitter, or qualified HVAC technician should perform pipe threading work in pressurized systems. Ensure the workpiece is securely clamped before tapping, and apply appropriate cutting fluid to extend tool life and improve thread quality. Follow all applicable codes, including IPC and IFGC, when threading pipe connections in gas or water systems. Inspect the finished threads before assembly to confirm full thread engagement and a proper seal.\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\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 042526019036\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: IR1903ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346372493618,"sku":"IR1903ZR","price":34.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499492.jpg?v=1782078579","url":"https:\/\/voomisupply.com\/products\/irwin-ir1903zr-npt-pipe-tap-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
