Built for use with manual ratchet and 3-way pipe threaders, these dies deliver consistent, code-compliant NPT threads in the field or shop. The alloy steel construction provides the hardness needed to hold a clean cutting edge through repeated use on steel, black iron, and galvanized pipe. Plumbers, pipefitters, and HVAC mechanics working with threaded pipe assemblies rely on this die set for accurate thread form and reliable fit-up with NPT fittings.\u003c\/p\u003e\n\u003cp\u003eThis die set is intended for manual pipe threading operations on 1-1\/4 inch pipe and conduit. It fits RIDGID OO-R, 11-R, 12-R, and O-R ratchet threaders as well as RIDGID 30A and 31A 3-way pipe threaders. The set is suited for residential and commercial plumbing, mechanical, and conduit work where NPT-threaded connections are required. The 4-piece configuration allows complete thread engagement around the pipe circumference for a clean, tapered NPT profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 1-1\/4-11-1\/2 NPT right-hand taper threads on 1-1\/4 inch pipe and conduit\u003c\/li\u003e\n  \u003cli\u003e4-piece die set for full circumferential thread cutting\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for extended cutting life and edge retention\u003c\/li\u003e\n  \u003cli\u003eCompatible with RIDGID OO-R, 11-R, 12-R, and O-R ratchet threaders\u003c\/li\u003e\n  \u003cli\u003eAlso fits RIDGID 30A and 31A 3-way pipe threaders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with RIDGID OO-R, 11-R, 12-R, and O-R ratchet threaders and RIDGID 30A and 31A 3-way pipe threaders.

Ensure the die set is properly seated and locked into the threader die head before beginning the threading operation. Apply cutting oil liberally during threading to reduce heat, extend die life, and produce a clean thread form. Inspect the finished thread for proper taper, depth, and engagement before assembling NPT fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 1-1\/4-11-1\/2 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\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: RIDGID\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RIDGID","offers":[{"title":"Default Title","offer_id":51525174067506,"sku":"D114","price":97.23,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/ridgid-37840-pipe-die-1-1-4-in-npt-right-hand-4-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
