21260 - ESAB 15ft Replacement Gas Hose for PT-31 Plasma Torch

Technical Overview of the ESAB 21260 Plasma Gas Hose

The ESAB 21260 is a specialized replacement gas hose designed for use with the PT-31 and PT-31XL series of plasma cutting torches. This component is critical for the safe and efficient transport of plasma gas (typically compressed air or nitrogen) from the power source to the torch head. Maintaining the integrity of the gas supply line is essential for achieving the high-velocity plasma stream required for cutting conductive metals.

Constructed to ESAB's rigorous Original Equipment Manufacturer (OEM) standards, this hose features durable outer sheathing capable of withstanding the harsh environment of industrial workshops, including exposure to sparks, abrasion, and dragging across concrete floors. The hose measures 15 feet in length, providing the operator with a significant working radius relative to the power supply unit. This length is standard for many PT-31 configurations, balancing reach with pressure maintenance.

The assembly comes with factory-installed fittings designed to mate correctly with the specific ports on the PT-31 torch handle and the machine output. Proper fitment is crucial to prevent gas leaks, which can lead to porosity in cuts, reduced consumable life, and potential safety hazards. As a direct replacement part, the 21260 eliminates the guesswork associated with universal hoses and ensures that flow rates meet the manufacturer's specifications for the torch.

Technicians and operators should inspect their existing hoses regularly for signs of dry rot, cracking, cuts, or crimping damage. A compromised hose can lead to pressure drops that destabilize the plasma arc. Replacing a damaged line with the ESAB 21260 restores the system to optimal operating parameters. This part is specifically the gas line component and does not include the power cable or pilot arc wire, which are separate components in the torch lead assembly.
