The interrupted thread geometry reduces cutting forces and helps clear chips more efficiently than standard continuous-thread taps, making it well suited for production tapping and difficult materials. With 5 flutes and a V-coating finish, this tap provides consistent thread form across its 1.062-inch thread length. The overall length of 2.563 inches and a 0.7-inch shank diameter make it compatible with standard tap holders and machine spindles. It is sold individually and is intended for use in machine tapping operations.\u003c\/p\u003e\u003cp\u003eThis tap is used in shops and field operations where NPT pipe threads must be cut into carbon steel, cast iron, die steel, or stainless steel workpieces. Typical applications include creating threaded ports in pipe fittings, manifolds, valve bodies, and mechanical assemblies that require pressure-rated tapered pipe thread connections. HVAC, plumbing, and industrial piping fabricators rely on NPT taps like this one to produce leak-resistant threaded joints in both production and repair scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInterrupted thread design reduces torque and improves chip evacuation during tapping\u003c\/li\u003e\n\u003cli\u003e3\/8-18 NPT thread standard for tapered pipe thread connections\u003c\/li\u003e\n\u003cli\u003e5-flute geometry for improved chip clearance in tough materials\u003c\/li\u003e\n\u003cli\u003eV-coating finish for extended tool life and reduced friction\u003c\/li\u003e\n\u003cli\u003eCompatible with carbon steel, cast iron, die steel, and stainless steel workpieces\u003c\/li\u003e\n\u003cli\u003eShank diameter of 0.7 inches fits standard tap holders and machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machine tapping applications requiring 3\/8-18 NPT threads in carbon steel, cast iron, die steel, and stainless steel.

Ensure the workpiece is securely fixtured and the tap is properly aligned before beginning the cut. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Follow all machine guarding and lockout procedures before changing or setting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: NPT\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.062 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: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron, Die Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 12053\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.207 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1205300408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739533541682,"sku":"1205300408","price":187.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/771d13d241b2017437bbf27e7f3dfaea.jpg?v=1788815842","url":"https:\/\/voomisupply.com\/products\/osg-1205300408-pipe-tap-3-8-18-npt-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
