Two-stage regulation minimizes delivery pressure variation, making it the correct choice for applications where pressure fluctuation would affect work quality or test accuracy. The body is die-forged brass for structural strength, and a fabric-reinforced neoprene diaphragm supports long service life. A precision-machined nozzle provides optimum flow control. This regulator is intended for use with medium to large oxygen cylinders in industrial, welding, and cutting applications.\u003c\/p\u003e\u003cp\u003eThe 0781-3503 suits medium-duty oxygen service across a range of professional applications including oxy-fuel welding, cutting, and brazing setups. Its two-stage design is particularly well suited for jobs where maintaining a stable delivery pressure is critical to process consistency, such as precision cutting operations or controlled test environments. It is sized for use with medium to large cylinders and is sold as an individual unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-stage regulation maintains constant delivery pressure over a range of decreasing inlet pressures\u003c\/li\u003e\n\u003cli\u003eDie-forged brass body and spring housing cap for extra strength and durability\u003c\/li\u003e\n\u003cli\u003eFabric-reinforced neoprene diaphragm for extended service life\u003c\/li\u003e\n\u003cli\u003eDelrin insert bushing for smoother, more durable adjustment\u003c\/li\u003e\n\u003cli\u003eStem-type seat mechanism uses inlet pressure to aid sealing\u003c\/li\u003e\n\u003cli\u003eStainless steel ball in adjusting screw for easy, consistent adjustment\u003c\/li\u003e\n\u003cli\u003eEvery unit factory-tested for quality assurance before shipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for medium-duty oxygen gas service with medium to large cylinders.

Always verify the cylinder valve, regulator inlet connection, and hose fittings are free of oil, grease, and contaminants before assembly, as these substances create a serious fire and explosion hazard in oxygen service. Shut off the cylinder valve and bleed all pressure from the system before connecting or disconnecting the regulator. Use only fittings and hoses rated for oxygen service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Type\u003c\/strong\u003e: Oxygen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulation Stages\u003c\/strong\u003e: Two stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Die-forged brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragm Material\u003c\/strong\u003e: Fabric-reinforced neoprene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 716352094306\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 0781-3503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VICTOR","offers":[{"title":"Default Title","offer_id":51343682830642,"sku":"0781-3503","price":764.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546332.jpg?v=1782023827","url":"https:\/\/voomisupply.com\/products\/victor-0781-3503-two-stage-oxygen-regulator","provider":"Voomi Supply","version":"1.0","type":"link"}
