A plasma arc torch includes at least one consumable component in coaxial relationship with another component of the torch. At least two compressible components are disposed between longitudinally extending coaxial surfaces of the consumable component and the second component. A pressurized medium flow path is directed to a longitudinal location between the compressible components. Upon supply of a pressurized medium through the flow path, the compressible components are caused to deform radially outward thereby centering the consumable component relative to the other component.
