Built from high speed steel with a bright uncoated finish, this tap produces the tapered, pressure-tight thread form required by the National Pipe Taper Fuel standard. It features 5 flutes for efficient chip evacuation and is classified as a short projection tap, with a projection of 0.565 inches and a thread length of 1.375 inches. The shank diameter measures 0.9063 inches and the square drive size is 0.679 inches. This tap is used by machinists, pipefitters, and plumbing trades when threading ports, fittings, and fluid system components to NPTF specification.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in pipe fittings, hydraulic manifolds, pneumatic components, and fluid system housings where an NPTF pressure-tight seal is required. The 3\/4-14 thread size is common in industrial plumbing, HVAC refrigerant piping, and compressed air systems. Short projection geometry makes it practical for use in confined bores or on machines with limited spindle clearance. It is appropriate for use in manual tapping and machine tapping applications at controlled speeds consistent with high speed steel tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-14 NPTF thread form produces pressure-tight tapered pipe threads per national fuel standard\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e5-flute design promotes chip clearance and thread quality during the cut\u003c\/li\u003e\n  \u003cli\u003eShort projection type suits restricted-depth bores and compact machine setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows direct inspection of tool condition between uses\u003c\/li\u003e\n  \u003cli\u003e0.9063-inch shank diameter and 0.679-inch square size for positive drive engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any manual or machine tapping application requiring a 3\/4-14 NPTF internal thread.

Always secure the workpiece firmly and use appropriate cutting fluid for the material being tapped to extend tool life and maintain thread quality. Set machine spindle speed consistent with high speed steel tooling recommendations for the workpiece material. Inspect the tap for wear or chipping before each use and replace if cutting edges show damage to avoid thread damage or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.565 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.9063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.679 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\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: R837533-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738427818290,"sku":"R837533-S","price":185.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a603150af6a3b2ef5f7daa52487c127.jpg?v=1788799416","url":"https:\/\/voomisupply.com\/products\/hertel-r837533-s-pipe-tap-3-4-14-nptf-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
