Built from high-speed steel with an elektraLUBE finish, this tap is engineered for threading pipe fittings, valves, and fluid-system components where a National Pipe Taper thread form is required. The 4-flute configuration provides stable chip evacuation and consistent thread geometry during cutting. With a 1.0625 inch thread length and a 0.5625 inch shank diameter, it fits standard tap handles and machine holders used in trade fabrication and repair work. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics are the primary installers.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading NPT connections in plumbing, HVAC, and industrial fluid-handling applications. It is used when creating new pipe thread entry points in manifolds, pipe end caps, valve bodies, or fittings that require a 1\/4-18 NPT female thread. It is appropriate for both bench work and light machine tapping in ferrous and non-ferrous materials. The elektraLUBE coating reduces friction and extends tool life in production and service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-18 NPT thread form for standard pipe thread connections\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eelektraLUBE finish reduces cutting friction and improves tool longevity\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes chip clearance and thread accuracy\u003c\/li\u003e\n\u003cli\u003e0.5625 inch shank diameter fits standard tap wrenches and holders\u003c\/li\u003e\n\u003cli\u003e1.0625 inch thread length accommodates full NPT taper engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style cutting tool for use wherever a 1\/4-18 NPT internal thread is required in pipe, fittings, or fluid-system components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by a qualified plumber, pipefitter, or machinist using a tap wrench or tapping machine set to the appropriate feed rate for the material being threaded. Ensure the workpiece is securely fixtured and the tap is started square to the drilled hole to avoid thread misalignment. Apply a suitable cutting fluid to supplement the elektraLUBE coating, particularly in steel or cast iron. Follow applicable trade codes and shop safety procedures when operating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard\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: 1.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.4210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.4590 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: elektraLUBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.145 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: 1310302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742378852658,"sku":"1310302","price":79.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54ebae2411815c0b42dbb562dadbd75b.jpg?v=1788837087","url":"https:\/\/voomisupply.com\/products\/osg-1310302-standard-pipe-tap-1-4-18-npt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
