Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers hardness and surface lubricity for consistent thread quality in production and repair environments. The tap features 4 flutes with a regular hook angle and a standard thread profile, giving machinists and tradespeople reliable chip clearance during through and blind-hole tapping operations. Overall length is 3.125 inches with a 1.375-inch thread length.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for plumbing, HVAC, and mechanical piping applications where NPTF-standard pressure-tight threads are required. It is used by pipefitters, plumbers, and machinists when threading ports in fittings, manifolds, valve bodies, and equipment housings. The NPTF profile produces a mechanically sealed joint without relying solely on thread sealant, making it appropriate for fuel, hydraulic, and pneumatic service ports. Series 118 designates its place in OSG's standard pipe tap lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-14 NPTF thread form for pressure-tight tapered pipe thread joints\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for strength across carbon steel, cast iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in repeat-use applications\u003c\/li\u003e\n  \u003cli\u003e4-flute design with regular hook for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStandard thread profile compatible with NPTF gauging requirements\u003c\/li\u003e\n  \u003cli\u003eShank diameter of 0.6875 inches with a square drive size of 0.515 inches for positive tap-wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/2-14 NPTF pipe thread forms in carbon steel, cast iron, and aluminum workpieces.

Secure the workpiece before tapping and use cutting oil or an appropriate tapping fluid to reduce heat buildup and improve thread finish. Apply even, consistent pressure and back off periodically to break chips and prevent tap binding. Do not force the tap if resistance increases unexpectedly, as HSS tooling is susceptible to breakage under torsional overload.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-14\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: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.515 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.579 inches\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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: 118\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.287 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: 1313005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747638477106,"sku":"1313005","price":135.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4907320c95e70a5f08ee69e2222cb683.jpg?v=1788883895","url":"https:\/\/voomisupply.com\/products\/osg-1313005-pipe-tap-1-2-14-nptf-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
