50FT Twin Welding Hose for Oxy-Acetylene Work

The VEVOR RTW1450A is a 50-foot twin welding hose designed for oxygen and acetylene gas supply. It features a 1/4-inch inner diameter and R-grade rubber construction for flexibility and kink resistance. The assembly suits cutting, soldering, and brazing tasks in workshop or industrial settings. It is not for applications requiring larger bore hoses or higher pressure ratings than specified.

300 PSI Working Pressure with B-Size Fittings

Maximum working pressure is rated at 300 PSI with a bursting pressure of 900 PSI for safety margin. Connections use 9/16"-18 UN threads: left-hand for the red acetylene line and right-hand for the green oxygen line. These Type B fittings match standard torch and regulator outlets. The hose cannot be used with proprietary quick-connect systems or fittings requiring different thread pitches.

Straightforward Installation with Bend Restrictors

Each hose end arrives with factory-fitted B-size fittings, so assembly is a matter of threading onto compatible regulators and torches. Integrated bend restrictors reduce sharp kinks at connection points during handling. The 50-foot length adds weight and coil memory that can complicate routing in tight spaces. Users without thread sealant or proper wrenches may experience leaks at the joints.

Questions about this item

Is the 50 ft length and 1/4 inch bore the only size available for this hose?

This model is supplied as a single 50 ft twin hose with a 1/4 inch inner diameter for both oxygen and acetylene lines.

What does the 300 PSI working pressure mean for daily cutting and brazing?

It means the hose is rated to handle up to 300 PSI continuously during welding, cutting or brazing tasks without exceeding its safe operating limit.

What do the 9/16"-18 LH and RH B fittings connect to, and what pressure do they seal up to?

The left-hand thread fits acetylene regulators and torches, the right-hand thread fits oxygen equipment, and both seal reliably at the hose's 300 PSI working pressure.
