In an elastic fluid turbine employing packing rings and spill strips or tip seals to minimize leakage between rotating and stationary components, an improvement in the packing rings and spill strips utilizing the combination of: a two-part packing ring and a two-part spill strip each comprising interconnected separate first and second half parts, the first half parts being disposed in annular grooves formed in stationary components of the turbine, the second half parts being partially disposed in clearance areas between the stationary components and rotating components, the second half parts having at least one seal tooth extending therefrom and disposed in close proximity to the rotating components, means for selectively varying the spacing between the half parts for adjusting the sealing dimensions of the packing ring and spill strip, and means for interconnecting the half parts to form an integral inseparable unit, the means for selectively varying the spacing between the half parts being a shim positioned in a groove in a lower face of the first half part, the second half part having an upper face bearing against the shim when the parts are mated.
