50FT Twin Welding Hose for Gas Welding

This 50-foot T-grade twin hose delivers oxygen and fuel gas to cutting torches and welding equipment. The 1/4-inch inner diameter handles oxygen, acetylene, propane and other fuel gases at up to 300 PSI working pressure. It suits professional welders and metal fabricators who need a long, flexible supply line for workshop or job-site use.

B-Size Fittings with Bend Restrictors

The green oxygen hose carries a 9/16"-18 right-hand thread and the red fuel hose a 9/16"-18 left-hand thread, matching standard B-size torch and regulator connections. A bend restrictor on each end reduces kinking at the fitting, helping the hose keep its shape during daily handling. The rubber construction resists abrasion and stays pliable in cold weather.

Pressure Limits Define Safe Use

Maximum working pressure is 300 PSI with a 900 PSI burst rating, so the hose must not be used with regulators or systems that exceed this limit. The 1/4-inch bore restricts flow volume compared with larger diameters, which can limit cutting speed on thick plate. Users needing higher flow or pressure should select a hose rated for those conditions.

Questions about this item

What does the 300 PSI working pressure limit mean for daily welding use?

The hose is rated for a maximum working pressure of 300 PSI and a burst pressure of 900 PSI, so it safely handles typical oxy-fuel cutting and welding pressures without exceeding its design limit.

What clearance is needed to route the 50 ft twin hose with its 9/16"-18 B fittings?

The assembled hose has an outer diameter of about 1.6 in and each end needs room for the 9/16"-18 left-hand and right-hand B fittings plus the bend restrictors that prevent kinking at the connections.

How do I attach the hose to my torch and regulator without crossing the threads?

Connect the green hose with the right-hand 9/16"-18 thread to the oxygen side and the red hose with the left-hand 9/16"-18 thread to the fuel-gas side; the colour code and thread direction prevent accidental reversal.
