Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts 1\/8-27 threads  -  27 threads per inch on a 1\/8-inch nominal pipe size  -  with a 4-flute configuration that promotes chip evacuation and stable thread formation. Overall length is 2.126 inches with a thread length of 0.75 inches. It is used by plumbers, pipefitters, machinists, and HVAC technicians who need to thread pipe ports in fittings, manifolds, and housings during fabrication or repair work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading straight fuel pipe ports in a shop or field setting. Rated for use in aluminum, carbon steel, cast iron, and hardened steel, it covers a wide range of base materials commonly encountered in mechanical, plumbing, and HVAC applications. The NPSF thread standard produces a straight, pressure-tight thread form used primarily in fluid and fuel system connections. The 4-flute geometry and regular hook angle work across general-purpose tapping operations on manual or machine tap drives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8-27 NPSF thread standard  -  straight fuel pipe thread for pressure-tight connections\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes chip removal and consistent thread quality\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across multiple materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish  -  no coating buildup to affect thread tolerance\u003c\/li\u003e\n\u003cli\u003eRegular hook angle suits general-purpose hand and machine tapping\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 2.126 inches fits tight-access tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting NPSF straight pipe threads in aluminum, carbon steel, cast iron, and hardened steel workpieces.

Apply consistent, steady pressure and back off periodically to break chips, especially in cast iron or hardened steel. Inspect the thread with a plug gauge after tapping to confirm fit before assembling pressurized fuel or fluid connections. Follow applicable mechanical and plumbing codes for thread engagement requirements on pressure-rated assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPSF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 27\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\u003eThread Profile\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\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.3280 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: Aluminum, Carbon Steel, Cast Iron, Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 109\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1332600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743330107698,"sku":"1332600","price":67.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5b0168302fdcafb8deb74d746b4b365.jpg?v=1788845718","url":"https:\/\/voomisupply.com\/products\/osg-1332600-pipe-tap-1-8-27-npsf-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
