Constructed from 4130 chromoly steel, this cylinder is engineered for demanding industrial and trade applications where gas containment integrity is critical. The CGA 540 valve connection is the standard fitting for oxygen service, making this cylinder compatible with regulators and equipment already in common use across welding, cutting, and medical-gas-adjacent industrial settings. The green paint finish follows standard color-coding conventions for oxygen cylinders. Licensed welding professionals, pipefitters, and industrial gas technicians are the primary users of this product.\u003c\/p\u003e\u003cp\u003eThis cylinder is suited for oxy-fuel welding, cutting, and brazing operations in fabrication shops, HVAC service, plumbing, and general industrial maintenance. The 40 cubic foot capacity makes it a practical mid-size option for field service work where portability matters but run time on a smaller cylinder would be limiting. The DOT and TC dual certification means this cylinder meets both United States and Canadian regulatory requirements for high-pressure gas transport and use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDOT-3AA2015 specification construction meets federal high-pressure cylinder standards\u003c\/li\u003e\n\u003cli\u003eDual DOT and TC certification for use in both the United States and Canada\u003c\/li\u003e\n\u003cli\u003e4130 chromoly steel construction provides high strength-to-weight ratio for field portability\u003c\/li\u003e\n\u003cli\u003eCGA 540 valve outlet is the industry-standard connection for oxygen service equipment\u003c\/li\u003e\n\u003cli\u003e40 cubic foot capacity suits field service and shop use without excessive bulk\u003c\/li\u003e\n\u003cli\u003eGreen painted finish follows standard oxygen cylinder color-coding conventions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CGA 540 oxygen regulators and compatible oxy-fuel equipment standard in welding, cutting, and brazing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOxygen cylinders must be handled and stored by qualified personnel following applicable regulations including DOT 49 CFR and CGA guidelines. Always secure the cylinder upright with a chain or strap before connecting any regulator. Keep oxygen cylinders away from oil, grease, and combustible materials at all times, as oxygen dramatically accelerates combustion. Never use a damaged valve or attempt to repair a valve in the field — return the cylinder to a licensed gas supplier for inspection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Type\u003c\/strong\u003e: Industrial Oxygen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 40 cubic feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Connection\u003c\/strong\u003e: CGA 540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Specification\u003c\/strong\u003e: DOT-3AA2015\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 4130 Chromoly Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Green Paint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 28.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: XTRWELD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CYLDSO540-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XTRWELD","offers":[{"title":"Default Title","offer_id":51347315622194,"sku":"CYLDSO540-40","price":18641.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546989.jpg?v=1782101297","url":"https:\/\/voomisupply.com\/products\/xtrweld-cyldso540-40-oxygen-cylinder-40-cu-ft-cga-540","provider":"Voomi Supply","version":"1.0","type":"link"}
