Built from high speed steel with a bright, uncoated finish, this tap produces accurate pipe threads used in fluid and gas line fittings across plumbing, HVAC, and mechanical piping applications. The short projection design keeps the tap compact and stable during threading operations. With 4 flutes and a 0.75-inch thread length, it delivers clean chip evacuation and consistent thread form in through and blind-hole applications. Machinists, pipefitters, and service technicians rely on this tap for tapping pipe fittings, manifolds, and threaded ports in a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis tap is suited for use in residential and light commercial trade applications where NPT pipe threads are required. Common install scenarios include threading ports on HVAC equipment, plumbing fittings, compressed air components, and hydraulic manifolds. The 1\/8-27 NPT thread size is one of the most common pipe thread sizes in North American trade work, used on pressure gauges, sensors, drain plugs, and small-diameter pipe connections throughout mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8-27 NPT thread size for standard tapered pipe thread applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose threading operations\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes efficient chip evacuation and thread quality\u003c\/li\u003e\n\u003cli\u003eShort projection tap type for compact, stable threading in tight spaces\u003c\/li\u003e\n\u003cli\u003e0.75-inch thread length accommodates typical pipe thread engagement depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose NPT pipe thread tapping in applications requiring a 1\/8-27 thread standard.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct NPT tap drill size before threading. Apply appropriate cutting fluid to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.241 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: 0.328 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: G837555-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735516381490,"sku":"G837555-S","price":35.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3d06bcb29937576f32009ec98ef827c.jpg?v=1788772808","url":"https:\/\/voomisupply.com\/products\/hertel-g837555-s-pipe-tap-1-8-27-npt-4-flutes-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
