Built from high speed steel with a bright uncoated finish, this tap is suited for threading operations in non-ferrous metals, aluminum, and steel. It features 4 flutes with a regular hook geometry and delivers a thread length of 1.063 inches over an overall length of 2.438 inches. The shank diameter measures 0.5625 inches. Machinists, pipefitters, and HVAC technicians reach for this tap when threading ports, fittings, and pipe connections that require a pressure-tight NPTF seal.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance threading applications where 1\/4-18 NPTF thread form is required. Common scenarios include threading pipe ports in HVAC manifolds, refrigeration service valves, hydraulic blocks, and plumbing fittings. The NPTF thread form creates a dry-seal mechanical thread fit without requiring sealant, making it appropriate for gas, air, and fluid service applications. It is suitable for both manual and machine tapping in bench and CNC environments across residential and light commercial trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPTF thread form produces a pressure-tight dry-seal connection without sealant\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides wear resistance across non-ferrous metals, aluminum, and steel\u003c\/li\u003e\n  \u003cli\u003e4-flute regular hook geometry supports both hand and machine tapping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual inspection of cutting edge condition\u003c\/li\u003e\n  \u003cli\u003eThread length of 1.063 inches and OAL of 2.438 inches suit standard pipe port depths\u003c\/li\u003e\n  \u003cli\u003eSquare drive shank with 0.4375-inch square length for positive tap wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/4-18 NPTF pipe ports in non-ferrous metals, aluminum, and steel workpieces.

Always use an appropriate cutting fluid matched to the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and back the tap out periodically to clear chips, particularly in blind-hole applications. Verify thread form with a NPTF thread gauge after tapping to confirm dry-seal fit before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.438 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: 0.421 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: 0.459 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Non-Ferrous Metal, Aluminum, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C64061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51721311060274,"sku":"C64061","price":75.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/579443c1052bd0c603dd1fa6f667957e.jpg?v=1788576238","url":"https:\/\/voomisupply.com\/products\/cleveland-c64061-nptf-pipe-tap-1-4-18-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
