The die-forged brass body and spring housing cap deliver the structural integrity required for high-pressure oxygen service. Delivery pressure ranges from 4 to 80 psig with a maximum inlet pressure of 3000 psig. The 0.082 Cv flow coefficient supports medium to high capacity general-purpose cutting, welding, and gas distribution applications. Licensed gas equipment technicians and welding professionals are the primary installers of this regulator.\u003c\/p\u003e\n\u003cp\u003eThe 0781-3505 is suited for applications where consistent, accurate outlet pressure is critical and where fluctuating delivery pressure would affect work quality or test results. The CGA 540 inlet connection pairs with standard high-pressure oxygen cylinders. The 9\/16 inch-18 RH(M) outlet connection is standard for medium-duty oxygen service hoses and torches. This regulator is appropriate for general-purpose industrial, fabrication, and laboratory oxygen systems requiring stable two-stage regulation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-stage regulation maintains constant delivery pressure across a decreasing inlet pressure range\u003c\/li\u003e\n  \u003cli\u003eDie-forged brass body and spring housing cap for strength and durability in high-pressure service\u003c\/li\u003e\n  \u003cli\u003eFabric-reinforced neoprene diaphragm (1.3 inches and 1 3\/4 inches) for precise, long-lasting performance\u003c\/li\u003e\n  \u003cli\u003eElectroless nickel-plated bronze sintered inlet filter protects internal components\u003c\/li\u003e\n  \u003cli\u003eDelrin insert bushing and stainless ball-in-key mechanism for smooth, easy pressure adjustment\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined nozzle and stem-type seat mechanism for maximum flow control and positive sealing\u003c\/li\u003e\n  \u003cli\u003eExternal self-reseating relief valve and pretested adjusting spring for quality assurance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard high-pressure oxygen cylinders using a CGA 540 inlet connection.

Always close the cylinder valve and bleed all pressure from the regulator before connecting or disconnecting. Do not use thread sealants, lubricants, or oil on any oxygen regulator fitting, as contact with hydrocarbons in an oxygen-enriched environment creates a fire and explosion hazard. Verify all connections are wrench-tight and leak-tested with an approved oxygen-compatible leak detection solution before placing the regulator into service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Two Stage, Medium Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Type\u003c\/strong\u003e: Oxygen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelivery Pressure Range\u003c\/strong\u003e: 4 to 80 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inlet Pressure\u003c\/strong\u003e: 3000 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gauge Range\u003c\/strong\u003e: 4000 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Gauge Range\u003c\/strong\u003e: 100 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Flow Coefficient\u003c\/strong\u003e: 0.082\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: CGA 540\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 9\/16 inch-18 RH(M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Size\u003c\/strong\u003e: 2 inches steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiaphragm\u003c\/strong\u003e: Fabric-reinforced neoprene, 1.3 inches and 1 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Die-forged brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Filter Material\u003c\/strong\u003e: Electroless nickel-plated bronze sintered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 7 inches x 7.4 inches x 6.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 716352093965\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: VICTOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0781-3505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VICTOR","offers":[{"title":"Default Title","offer_id":51343001321778,"sku":"0781-3505","price":762.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546317.jpg?v=1782013377","url":"https:\/\/voomisupply.com\/products\/victor-0781-3505-two-stage-oxygen-regulator-4-80-psig","provider":"Voomi Supply","version":"1.0","type":"link"}
