Built from high speed steel with a titanium nitride (TiN) coating, the tap delivers extended tool life and reduced friction during cutting. The short projection design and 4-flute geometry provide stable chip evacuation in through and blind-hole applications. Machinists, pipefitters, and maintenance technicians use this tap when threading ports, fittings, and pipe connections that require a pressure-tight NPTF seal.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 1\/2-14 NPTF pipe thread connections in production and maintenance environments alike. Common applications include creating leak-free threaded ports in hydraulic manifolds, pneumatic housings, plumbing fixtures, and fluid-system components. The NPTF thread form produces a dry-seal thread that does not rely on a sealant to hold pressure, making it a standard choice for compressed air, fuel, and hydraulic plumbing work. The short projection style fits into tight clearances where a longer shank would interfere with fixturing or workpiece geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPTF thread standard for dry-seal, pressure-tight pipe thread connections\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life compared to uncoated taps\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes stable chip flow and consistent thread form\u003c\/li\u003e\n  \u003cli\u003eShort projection geometry fits restricted-clearance setups\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch thread length accommodates standard pipe wall thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production pipe tap for any application requiring a 1\/2-14 NPTF thread in compatible materials; fits standard tap holders and machines accepting a 0.6875-inch shank diameter with a 0.5150-inch square drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a machinist or qualified maintenance technician using an appropriate tap wrench, drill press, or CNC tapping head. The workpiece hole must be drilled to the correct tap drill size for 1\/2-14 NPTF prior to threading. Use a suitable cutting fluid for the material being tapped to protect the cutting edges and improve thread finish. Inspect the tap for wear or chipping regularly, and never force a tap that has bottomed out or encountered unexpected resistance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 0.5150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.4640 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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R837574T-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51993728319794,"sku":"R837574T-S","price":166.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3274995c45835d2f099ab6ee9b1ccf55.jpg?v=1789991319","url":"https:\/\/voomisupply.com\/products\/hertel-r837574t-s-pipe-tap-1-2-14-nptf-4-flute-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
