The die head produces right-hand threads using alloy steel dies, delivering the thread form and durability required in professional plumbing and pipefitting work. This die head mounts to the RIDGID 12-R manual pipe threader, making it a direct field replacement or additional-size head for technicians who thread pipe by hand. Alloy steel construction holds cutting edge integrity across repeated use on steel pipe.\u003c\/p\u003e\n\u003cp\u003eThis die head is used in plumbing rough-in, mechanical piping, and gas line work where 1\/2 inch NPT threaded connections are required. It is suited for residential and light commercial applications. Plumbers and pipefitters use 12-R manual threaders in tight spaces or in the field where power threading equipment is not practical. The 37390 die head allows a technician to swap sizes on the same 12-R handle rather than carrying multiple tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 1\/2 inch nominal NPT right-hand threads\u003c\/li\u003e\n  \u003cli\u003eAlloy steel dies for extended cutting edge life\u003c\/li\u003e\n  \u003cli\u003eDirect-fit head for the RIDGID 12-R manual pipe threader\u003c\/li\u003e\n  \u003cli\u003eNPT thread form meets standard tapered pipe thread requirements for pressure fittings\u003c\/li\u003e\n  \u003cli\u003eSwappable die head design allows one 12-R handle to serve multiple pipe sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with RIDGID 12-R manual pipe threaders.

Before threading, ensure the pipe is properly reamed and deburred to protect die life and thread quality. Apply thread cutting oil liberally during the threading operation to reduce heat and extend die life. Follow applicable code requirements, including IPC and IFGC, for thread engagement length and joint compound use on pressure systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch nominal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right-hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDie Material\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tool\u003c\/strong\u003e: RIDGID 12-R Manual Pipe Threader\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: 37390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RIDGID","offers":[{"title":"Default Title","offer_id":51525356388658,"sku":"DHC12R12","price":177.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e2db79863c3087811c5278b5c9b8060.jpg?v=1785471492","url":"https:\/\/voomisupply.com\/products\/ridgid-37390-12-r-die-head-1-2-inch-npt-manual-pipe-threader","provider":"Voomi Supply","version":"1.0","type":"link"}
