Built from high speed steel with a titanium nitride (TiN) coating, it produces a 1\/8-27 thread form meeting National Pipe Taper Fuel (NPTF) standards for pressure-tight, dry-seal connections. The 4-flute geometry provides balanced cutting action and chip clearance in short-chipping materials. With an overall length of 2.125 inches and a thread length of 0.75 inches, this tap is sized for compact pipe fitting applications. It is used by licensed plumbers, pipefitters, HVAC technicians, and machining trades when threading ports, fittings, and manifold bodies.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 1\/8-27 NPTF connections in cast iron, stainless steel, and carbon steel workpieces. Typical applications include threading sensor ports, pressure tap locations, valve bodies, and hydraulic or pneumatic manifold entries where a pressure-tight pipe thread is required. The TiN finish reduces friction during cutting and extends tool life compared to uncoated HSS. It is appropriate for both production and maintenance tapping operations across HVAC, plumbing, and industrial service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8-27 NPTF thread form for dry-seal, pressure-tight pipe connections\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles cast iron, stainless steel, and carbon steel\u003c\/li\u003e\n\u003cli\u003eTiN (titanium nitride) coating reduces cutting friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e4-flute design provides balanced cutting and chip evacuation in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eRegular hook geometry suited for standard machine and hand tapping operations\u003c\/li\u003e\n\u003cli\u003eCompact 2.125-inch overall length fits restricted-access port locations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 1\/8-27 NPTF pipe threads in cast iron, stainless steel, and steel workpieces.

Always apply appropriate cutting fluid for the material being tapped, and ensure the starting hole is drilled to the correct tap drill size for 1\/8-27 NPTF before threading. De-energize and depressurize any system before tapping into live assemblies. Follow applicable codes and manufacturer guidelines for thread engagement depth on pressure-rated connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 27\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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.3280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.3120 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\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\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: C55682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692641059122,"sku":"C55682","price":355.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d226d5ca69ca709b503fc9244e9e70b.jpg?v=1788300438","url":"https:\/\/voomisupply.com\/products\/cleveland-c55682-nptf-pipe-tap-1-8-27-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
