Built for professional welders, HVAC technicians, and plumbers who use torch equipment in the field, this hose delivers reliable gas flow at a maximum working pressure of 200 psi. The twin-hose construction is color coded for safety: red for acetylene fuel gas with left-hand thread fittings, and green for oxygen with right-hand thread fittings. Eight-sided crimp ferrules secure each end connection, resisting pull-out and leakage under sustained working conditions.\u003c\/p\u003e\u003cp\u003eThe h34b is suited for oxyacetylene torch work in residential and commercial settings, including brazing, soldering, cutting, and heat-shrink applications common in HVAC and plumbing service. The 50-foot length provides extended reach from a regulator station to the work area, reducing the need to reposition gas cylinders. B-size fittings are compatible with standard B-size torch handles and regulators. The Grade R rating confirms the hose meets industry standards for use with acetylene and oxygen service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eColor-coded twin hose: red for acetylene with left-hand thread fittings, green for oxygen with right-hand thread fittings\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 200 psi for both hose lines\u003c\/li\u003e\n\u003cli\u003eEight-sided crimp ferrules for secure, leak-resistant end connections\u003c\/li\u003e\n\u003cli\u003eGrade R construction rated for oxyacetylene service\u003c\/li\u003e\n\u003cli\u003eB-size fitting connections for use with standard torch handles and regulators\u003c\/li\u003e\n\u003cli\u003e50-foot length provides extended reach at the work site\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with B-size oxyacetylene torch handles and regulators in standard oxyacetylene welding and cutting setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and connection of oxyacetylene hoses should be performed by a qualified technician familiar with compressed gas safety procedures. Always shut off cylinder valves and bleed pressure from both hose lines before disconnecting or connecting fittings. Inspect the hose for cuts, abrasions, or damage before each use, and never use petroleum-based lubricants on oxygen-side fittings. Follow applicable NFPA 51 and CGA guidelines for oxyacetylene equipment setup and use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Length\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Inner Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Grade\u003c\/strong\u003e: Grade R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxygen Hose Color\u003c\/strong\u003e: Green, right-hand thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcetylene Hose Color\u003c\/strong\u003e: Red, left-hand thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFerrule Type\u003c\/strong\u003e: Eight-sided crimp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.5 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: UNIWELD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: h34b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UNIWELD","offers":[{"title":"Default Title","offer_id":51138360508722,"sku":"H34B","price":119.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531355.jpg?v=1778254231","url":"https:\/\/voomisupply.com\/products\/uniweld-h34b-twin-welding-hose-50-ft-3-16-inch-200-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
