It features a 9\/16 inch right-hand thread (UNF standard) and a 1\/4 inch inner diameter, making it a direct-connect fitting for low-pressure oxygen hose assemblies. The brass construction resists corrosion and meets the material compatibility requirements for oxidizing gas service. Welders, gas-supply technicians, and industrial maintenance professionals install this coupling when assembling or repairing oxygen delivery hose runs in welding and cutting setups.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for use in both shop and field welding environments where oxygen hose connections require a threaded, mechanically secure fitting. The right-hand thread orientation follows standard oxygen-side convention, distinguishing it from fuel-gas fittings that use left-hand threads. Typical applications include oxy-fuel cutting rigs, welding stations, and industrial gas distribution lines where reliable, leak-resistant hose terminations are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for compatibility with oxygen service and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch UNF right-hand thread follows standard oxygen-line thread convention\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch inner diameter suits common oxygen hose sizes\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type provides a secure, field-serviceable joint\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy handling during hose assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for oxygen hose assemblies using a 9\/16 inch right-hand UNF threaded coupling with 1\/4 inch ID hose.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified welder or gas-supply technician familiar with compressed-gas hose fittings. Always shut off the oxygen supply valve and bleed residual pressure from the hose before replacing or installing any coupling. Use only tools and thread sealants approved for oxygen service — never apply standard pipe dope or petroleum-based compounds to oxygen fittings, as these create a fire and explosion hazard. Inspect threads and seating surfaces for damage before assembly and pressure-test the connection before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oxygen Line\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: DIXON VALVE COUPLING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC1520409K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIXON VALVE \u0026 COUPLING","offers":[{"title":"Default Title","offer_id":51698186649906,"sku":"MSC1520409K","price":17.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa62e85b3d8c24ba79ec8c623adf9e30.jpg?v=1788359001","url":"https:\/\/voomisupply.com\/products\/dixon-valve-coupling-msc1520409k-oxygen-hose-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
