Flexible hose

From GAWDAwiki

Flexible hose is ideal for welding operations. Hoses connecting torches to regulators must have sufficient flexibility to allow easy movement of the torch, while being able to withstand pressures of up to 100 psig.^[1]

Flexible hose comes in various diameters and at varying lengths. It may come on or off a reel.^[2]
