It transitions to a 3\/8 inch NPTF threaded port, providing a secure, leak-resistant connection between hose assemblies and welding equipment fittings. At 1.3 inches in overall length and weighing 0.1 pounds, it is a compact fitting suited for use in gas welding and cutting setups. Left hand thread engagement confirms correct orientation for fuel gas service. Brass construction offers corrosion resistance and durability in typical welding gas environments. Licensed plumbers, pipefitters, and welding equipment technicians are the primary installers of this type of adapter.\u003c\/p\u003e\u003cp\u003eThis adapter is used in welding and cutting gas supply lines where a left hand threaded hose must connect to NPTF-ported equipment or regulators. The 9\/16 inch UNF left hand thread is standard for fuel gas hose fittings in oxy-fuel welding systems. The 3\/8 inch NPTF port is a common connection size on regulators, torches, and manifold systems. It is appropriate for residential welding shops, commercial fabrication facilities, and field service applications where hose-to-equipment transitions are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft hand thread confirms fuel gas service and prevents misconnection with oxygen-side fittings\u003c\/li\u003e\n\u003cli\u003e9\/16 inch UNF left hand thread on hose side matches standard fuel gas hose ends\u003c\/li\u003e\n\u003cli\u003e3\/8 inch NPTF port provides a pressure-tight tapered thread connection\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in welding gas service environments\u003c\/li\u003e\n\u003cli\u003eCompact 1.3 inch overall length fits tight installation spaces\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.1 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for welding hose assemblies using 9\/16 inch left hand thread fuel gas hose connections with 3\/8 inch NPTF equipment ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, welding equipment technician, or licensed plumber familiar with compressed gas fittings and applicable codes. Shut off all gas supply valves and bleed pressure from the line before removing or installing any fitting. Left hand threads tighten counterclockwise — do not apply standard pipe thread sealants to NPTF fittings unless the sealant is rated for fuel gas service. Inspect threads for damage before assembly and leak-test all connections with an approved gas leak detection solution after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Thread Size\u003c\/strong\u003e: 9\/16 inch UNF Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPTF Thread Size\u003c\/strong\u003e: 3\/8 inch NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIXON VALVE COUPLING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1580906C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIXON VALVE \u0026 COUPLING","offers":[{"title":"Default Title","offer_id":51693346881842,"sku":"1580906C","price":15.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d36c818fc4b5108b1379f00b4ec99753.jpg?v=1788311026","url":"https:\/\/voomisupply.com\/products\/dixon-valve-coupling-1580906c-welding-hose-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
