Uniweld h34b Twin Welding Hose 50 Ft 3/16 Inch 200 Psi

Product Description

The UNIWELD h34b is a 50-foot Grade R oxyacetylene twin welding hose designed for use with oxygen and acetylene gas systems. 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.

The 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.

Installation Notes

Installation 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.
