571F73 - ESAB Grade RM Twin Welding Hose 3/16" x 25.5' with A-A Fittings

Precision and Flexibility: ESAB 3/16" Twin Welding Hose

Upgrade your light-duty oxy-fuel equipment with the ESAB 571F73 Twin Welding Hose, a high-quality replacement or extension hose designed for precision applications. This hose assembly is manufactured to Grade RM specifications, meaning the liner and cover are specifically formulated to handle Acetylene fuel gas and Oxygen. It is important to note that Grade RM is not suitable for alternate fuels like Propane or Propylene; it is optimized strictly for Acetylene, providing superior performance and safety for that specific gas.

One of the standout features of this SKU is its 3/16-inch nominal ID. While 1/4-inch hose is the industry standard for heavy-duty structural work, 3/16-inch hose is the preferred choice for light-duty manufacturing, aircraft welding, and art fabrication. The smaller diameter results in a much lighter hose that drags less on the torch, giving the welder greater control over the puddle and reducing wrist strain during intricate maneuvers. The hose is 25.5 feet long, providing ample reach for standard shop layouts.

The assembly is terminated with Type "A" fittings (3/8"-24) on both ends. These smaller fittings are distinct from the standard "B" fittings (9/16"-18) found on larger equipment. Before purchasing, verify that your regulator and torch handle are equipped with "A" size outlets/inlets. If you are running a light-duty aircraft-style torch, this is likely the exact hose you need. The durable rubber cover resists sparks, abrasion, and ozone cracking, ensuring a long service life in professional welding environments.
