Built from high speed steel with a titanium nitride (TiN) coating, this tap offers increased surface hardness and wear resistance compared to uncoated HSS tools. It features 4 flutes with a regular hook geometry, a thread length of 1.375 inches, and an overall length of 3.125 inches. The TiN finish reduces friction during threading, extending tool life in production and field service environments. Licensed machinists, pipefitters, and plumbers use this tap when creating pressure-rated pipe thread connections.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 1\/2-14 NPTF pipe threads in cast iron, stainless steel, and steel workpieces. Typical applications include fabricating threaded pipe fittings, manifolds, hydraulic blocks, and valve bodies in commercial plumbing, industrial piping, and mechanical service work. The NPTF thread form produces a pressure-tight seal through thread interference, making it the correct choice where dryseal performance is required without relying solely on sealant. It is sold individually with a minimum order quantity of 3.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNPTF dryseal thread form — 1\/2-14 thread size for pressure-tight connections\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in ferrous metals\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces cutting friction\u003c\/li\u003e\n\u003cli\u003e4-flute regular hook geometry for balanced chip flow\u003c\/li\u003e\n\u003cli\u003eThread length of 1.375 inches; overall length of 3.125 inches\u003c\/li\u003e\n\u003cli\u003eShank diameter of 0.6875 inches with a 0.515-inch square drive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1\/2-14 NPTF threads in cast iron, stainless steel, and steel.

Always use appropriate cutting fluid for the workpiece material — particularly important with stainless steel to prevent galling. Ensure the workpiece is securely clamped and the tap is started square to the hole before applying cutting pressure. De-burr and clean threads after tapping before assembling any pressure-rated fittings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\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\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\u003eSquare Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 975TN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C55685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695113699634,"sku":"C55685","price":463.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79e05e11f44361f496bc0e87dc496b0c.jpg?v=1788331442","url":"https:\/\/voomisupply.com\/products\/cleveland-c55685-pipe-tap-1-2-14-nptf-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
