This tap produces the tapered thread profile required by the National Pipe Taper standard, creating leak-resistant threaded joints when properly used with compatible fittings. It is a hand or machine tap intended for use by plumbers, pipefitters, and mechanical tradespeople working on pipe assembly and repair in both new construction and retrofit applications. Sold individually, it is suited for low-volume precision work where a single tap size is needed.\u003c\/p\u003e\n\u003cp\u003eThis tap is used when threading pipe connection points in plumbing, HVAC piping, and general mechanical systems where NPT fittings are the standard. It is appropriate for residential and light commercial applications wherever a 1\/2 inch NPT threaded port must be cut or restored in metal pipe, fittings, or manifold bodies. Pipefitters and plumbers commonly reach for this tool when adding threaded ports to existing assemblies or cleaning up damaged threads in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPT thread profile for tapered, pressure-resistant threaded connections\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch nominal pipe size for standard half-inch pipe fittings\u003c\/li\u003e\n  \u003cli\u003eCompatible with hand tapping and machine tapping operations\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction for consistent thread cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading tool for use with standard 1\/2 inch NPT fittings and pipe connections in plumbing and piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePipe taps are typically used by licensed plumbers and pipefitters working under applicable plumbing codes such as the IPC or IFGC. Always secure the workpiece firmly before tapping and use an appropriate cutting fluid to extend tap life and improve thread quality. Back the tap out periodically to clear chips and reduce the risk of tap breakage. Inspect finished threads with a compatible NPT fitting before pressurizing the connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 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: 042526019050\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR1905ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346106548530,"sku":"IR1905ZR","price":79.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551766.jpg?v=1782071045","url":"https:\/\/voomisupply.com\/products\/irwin-ir1905zr-npt-pipe-tap-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
