It is manufactured from high speed steel (HSS) and carries a bright, uncoated finish. The tap features 4 flutes and a short projection design, which helps control chip evacuation in tight or blind-entry applications. The thread length measures 11\/16 inches, and the shank diameter is 0.3125 inches. Plumbers, pipefitters, HVAC technicians, and maintenance machinists use this tap when threading ports, fittings, or manifold passages that must accept 1\/16-27 NPTF pipe thread connections.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance environments where NPTF pressure-tight pipe thread forms are required. Typical applications include threading ports in valve bodies, hydraulic manifolds, refrigeration components, and fluid-handling assemblies. The NPTF thread form produces a dry, mechanically sealed joint without relying solely on sealant, making it common in plumbing, HVAC, and industrial fluid-system work. The short projection geometry keeps the cutting section compact, which is useful when working in confined or partially obstructed drilling fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/16-27 NPTF thread form for pressure-tight pipe thread connections\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes chip clearance and consistent thread finish\u003c\/li\u003e\n  \u003cli\u003eShort projection tap type for use in tight or fixture-constrained setups\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose tapping with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003e0.2340-inch square drive size compatible with standard tap wrenches and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock pipe tap for applications requiring 1\/16-27 NPTF internal threads in metal components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist, pipefitter, or HVAC technician using a calibrated tap wrench or tapping head. The workpiece should be secured and the pilot hole drilled to the correct tap-drill diameter for 1\/16-27 NPTF before tapping begins. Apply an appropriate cutting fluid for the base material to extend tool life and improve thread finish. Reverse the tap periodically to break chips and prevent thread damage or tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/16-27\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\u003eThread Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.2410 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\u003eWeight\u003c\/strong\u003e: 0.06 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G837527-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755285184818,"sku":"G837527-S","price":61.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b122e13ab6d86c0ab7b95d3df0cd0d79.jpg?v=1788953096","url":"https:\/\/voomisupply.com\/products\/hertel-g837527-s-pipe-tap-1-16-27-nptf-4-flutes-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
