It cuts tapered National Pipe Thread (NPT) threads into pipe ends and pipe fittings, conforming to the standard taper profile required for pressure-tight connections. Plumbers, pipefitters, and mechanical contractors use this tap when threading large-diameter pipe in the field or shop. At 4 pounds, this is a heavy-duty tool sized for substantial material removal in pipe threading applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for large-diameter piping work in industrial, commercial, and heavy mechanical environments. The 3-1\/2-inch NPT size is most commonly encountered in industrial process piping, large commercial plumbing headers, and heavy mechanical system installations. A threading machine or large tap wrench with adequate torque capacity is required for a tap of this size. It is not a common residential application tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS construction provides hardness and wear resistance for threading steel and iron pipe\u003c\/li\u003e\n  \u003cli\u003e3-1\/2-inch NPT size handles large-diameter pipe threading in industrial and commercial applications\u003c\/li\u003e\n  \u003cli\u003e8 TPI thread pitch conforms to the NPT standard taper specification for that pipe size\u003c\/li\u003e\n  \u003cli\u003eTapered thread form creates pressure-sealing engagement without additional fittings or inserts\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit, suitable for single-job procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for threading 3-1\/2-inch NPT connections in steel, cast iron, or ductile iron pipe and fittings where the NPT taper standard applies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed and operated by a qualified pipefitter, plumber, or machinist familiar with large-diameter pipe threading procedures. A power threading machine or heavy-duty tap wrench rated for the torque demands of a 3-1\/2-inch tap is required. Apply a suitable cutting oil throughout the threading operation to reduce heat and extend tool life. Always deburr and chamfer the pipe end before tapping to reduce the risk of tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PT-35000-8-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233705460018,"sku":"PT-35000-8-I","price":654.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623559.png?v=1780107210","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-pt-35000-8-i-hss-npt-pipe-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
