It is built from high-speed steel (HSS) with a bright, uncoated finish and features 4 flutes for chip evacuation during threading operations. The tap measures 2.563 inches in overall length with a 1.0625-inch thread length, a 0.700-inch shank diameter, and a 0.531-inch square size. It carries a regular hook profile and is intended for use by machinists, pipefitters, and plumbing trades requiring precision pipe thread cutting in production or field repair settings.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading carbon steel, cast iron, and aluminum workpieces. NPTF threads provide a pressure-tight seal without relying solely on thread sealant, making this tap appropriate for hydraulic, pneumatic, and fuel line fittings as well as plumbing and HVAC piping connections. It is a single-piece, hand or machine tap compatible with standard tap wrenches and CNC tapping operations where a 3\/8-18 NPTF internal thread is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-18 NPTF thread form for pressure-tight pipe thread connections\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across carbon steel, cast iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes chip evacuation and thread quality\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose tapping applications\u003c\/li\u003e\n  \u003cli\u003eRegular hook profile compatible with hand tapping and machine tapping setups\u003c\/li\u003e\n  \u003cli\u003eCompact 2.563-inch overall length for use in confined tapping situations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pipe tap for use in any application requiring a 3\/8-18 NPTF internal thread in carbon steel, cast iron, or aluminum material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be used by qualified machinists, pipefitters, or plumbers familiar with pipe thread cutting procedures. Always secure the workpiece and use appropriate cutting fluid to extend tap life and improve thread quality. Apply consistent, controlled torque and back off periodically to break chips, especially in blind-hole applications. Follow applicable OSHA machine guarding and shop safety requirements when operating in a powered tapping setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Profile\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.251 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 12006\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1200600800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728692773170,"sku":"1200600800","price":76.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3fe8839876683727f6342f2fcc7c371_c675373a-f5e8-44c7-a735-844c57b0ad3e.jpg?v=1788695128","url":"https:\/\/voomisupply.com\/products\/osg-1200600800-pipe-tap-3-8-18-nptf-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
