Made from high carbon steel (HCS), it delivers the hardness needed to thread or rethread steel and iron pipe in the field or shop. The hex body allows standard die stock or wrench engagement for controlled torque during threading. Plumbers, pipefitters, and mechanical contractors reach for this die when restoring damaged threads or cutting new NPT threads on cut-to-length pipe sections.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for residential and light commercial plumbing, gas piping, and mechanical piping applications where 3\/8-inch NPT connections are standard. It is commonly used during pipe repair, rough-in work, or maintenance service calls where a threading machine is not on site. The compact hex design makes it practical for tight spaces and field use without dedicated threading equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-18 NPT thread form for standard tapered pipe thread cutting and rethreading\u003c\/li\u003e\n  \u003cli\u003eHex body profile accepts standard die stocks and adjustable wrenches for field use\u003c\/li\u003e\n  \u003cli\u003eHigh carbon steel construction provides hardness and edge retention on steel and iron pipe\u003c\/li\u003e\n  \u003cli\u003eRethreading geometry suited for cleaning and restoring damaged or corroded pipe threads\u003c\/li\u003e\n  \u003cli\u003eSold individually, no additional dies required for single-size work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard hex die stocks sized for 3\/8-18 NPT hex dies.

Shut off and depressurize the line before rethreading any in-service pipe. Apply cutting oil generously during threading to extend die life and produce clean thread form. Inspect finished threads with a NPT thread gauge or mating fitting before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDie Style\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel (HCS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR7404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51347030081842,"sku":"IR7404","price":23.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499832.jpg?v=1782097005","url":"https:\/\/voomisupply.com\/products\/irwin-ir7404-hex-pipe-rethreading-die-3-8-18-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
