Built around a forged brass body with zinc-aluminum housing caps and a fabric-reinforced neoprene diaphragm measuring 2.7 inches, it delivers outlet pressure from 5 to 125 psig with a maximum inlet pressure of 3000 psig. The 0.488 Cv flow coefficient provides uniform flow performance with high sensitivity and accuracy. A 540 CGA inlet connection pairs with a 9\/16 inch-18 RH(M) outlet connection. Licensed HVAC, welding, and industrial gas technicians install this regulator in oxygen supply systems for cutting, welding, and fabrication operations.\u003c\/p\u003e\n\u003cp\u003eThis regulator is suited for industrial and general fabrication, light fabrication, structural steel fabrication, and repair and maintenance applications. Its compact layout places built-in gauges recessed into the body for physical protection. The 1.5-inch UL listed gauges feature a 4000 psig inlet range and a 200 psig outlet range with enhanced graphics for easy reading. Color-coded knobs allow quick gas identification, and the side-mounted knob supports natural, safe hand positioning during pressure adjustment. The high-impact ABS gauge guard adds a further layer of protection in demanding shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged brass body with zinc-aluminum housing caps for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e0.488 Cv flow coefficient delivers uniform flow across varying cylinder pressures\u003c\/li\u003e\n  \u003cli\u003eExternal self-reseating relief valve with stem-type seat mechanism for system integrity\u003c\/li\u003e\n  \u003cli\u003eNickel-plated bronze sintered inlet filter protects internal components from contamination\u003c\/li\u003e\n  \u003cli\u003eColor-coded SLAM impact-absorbing safety knob protects regulator internals on single-point impact\u003c\/li\u003e\n  \u003cli\u003eRecessed built-in gauges with high-impact ABS gauge guard resist job-site damage\u003c\/li\u003e\n  \u003cli\u003eMeets or exceeds CGA E-4, UL 252, and ASTM G-175 promoted ignition test standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style two-stage high-capacity oxygen regulator for use with standard 540 CGA oxygen cylinder valves in industrial and light fabrication supply systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and adjustment of high-pressure oxygen regulators should be performed by a qualified technician familiar with compressed gas handling procedures. Always shut off the cylinder valve and bleed the regulator before connecting or disconnecting. Keep all fittings, tools, and the regulator free of oil, grease, and combustible contaminants, as oxygen service demands strict cleanliness. Follow CGA and applicable local codes governing compressed gas equipment installation and use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Pressure Range\u003c\/strong\u003e: 5-125 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 Connection\u003c\/strong\u003e: 540 CGA\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\u003eCv Flow Coefficient\u003c\/strong\u003e: 0.488\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiaphragm Size\u003c\/strong\u003e: 2.7 inches, fabric-reinforced neoprene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Size\u003c\/strong\u003e: 1.5 inches, UL listed\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: 200 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Forged brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 6.85 inches x 4.72 inches x 4.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.64 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CGA E-4, UL 252, ASTM G-175\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Five years\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: 0781-5218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VICTOR","offers":[{"title":"Default Title","offer_id":51345820877106,"sku":"0781-5218","price":924.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546310.jpg?v=1782063866","url":"https:\/\/voomisupply.com\/products\/victor-0781-5218-two-stage-high-capacity-oxygen-regulator","provider":"Voomi Supply","version":"1.0","type":"link"}
