It produces a 1\/2-14 NPTF thread form, which is the dryseal pipe thread standard used in hydraulic, pneumatic, and fluid-system connections where a pressure-tight seal without a sealant compound is required. Manufactured from high-speed steel for durability under demanding cutting conditions, the tap features an elektraLUBE coating that reduces friction during the tapping operation and extends tool life. With 4 flutes and a 1.375-inch thread length, it suits production and maintenance tapping in ferrous and non-ferrous materials. Plumbers, pipefitters, machinists, and HVAC technicians working with threaded pipe connections regularly use this tool.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1313002 is suited for threading pipe connections in residential and commercial plumbing, HVAC refrigerant line assemblies, pneumatic systems, and hydraulic manifold work. It is used wherever a 1\/2-14 NPTF dryseal thread is required in a tapped hole. The 4-flute design is appropriate for through-hole and short blind-hole applications in softer to medium-hardness materials. It is a hand-tap style intended for use in a tap wrench or machine tapping setup at appropriate speeds for the base material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-14 NPTF thread form produces dryseal tapered pipe threads for pressure-tight connections\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides strength and wear resistance across a range of materials\u003c\/li\u003e\n  \u003cli\u003eelektraLUBE coating reduces cutting friction and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003e4-flute design delivers clean thread form and stable cutting action\u003c\/li\u003e\n  \u003cli\u003e1.375-inch thread length accommodates standard pipe fitting engagement depths\u003c\/li\u003e\n  \u003cli\u003eOSG Series 118 standard tap geometry for consistent, repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stocking tap for any application requiring a 1\/2-14 NPTF dryseal tapered pipe thread in metal.

Secure the workpiece firmly and align the tap perpendicular to the drilled hole before applying torque. When machine tapping, use appropriate spindle speeds for high-speed steel tooling in the material being threaded. Inspect the tap for wear or chipping between uses, as a damaged tap can produce out-of-tolerance threads that compromise seal integrity in pressure applications.\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\u003eThread Profile\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.375 inches\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\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\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\u003eSeries\u003c\/strong\u003e: 118\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.288 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: 1313002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743873106226,"sku":"1313002","price":147.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa3f8cc8e989fc6bf8222e68566123ab_adc62288-47e9-49bf-8739-434dbfe16443.jpg?v=1788850629","url":"https:\/\/voomisupply.com\/products\/osg-1313002-pipe-tap-1-2-14-nptf-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
