An arrangement for statically sealing between the inner shrouds of an annular array of stationary stator vanes and a radially-inner, annular seal housing of a gas turbine, comprising: first, outer seal means carried by said housing and comprising a first plurality of arcuate segments in end-to-end relation substantially completing a circle, each said segment being generally channel-shaped in cross section throughout its length, and being radially movably disposed in a radially-outwardly-open channel in said housing; second, inner seal means radially movably disposed in said first seal means channel and including a second plurality of arcuate segments equalling the number of said shrouds, in end-to-end relation substantially completing a circle; first resilient means biasing said first seal means radially outwardly in said housing channel; and second resilient means independently biasing said second seal means radially outwardly in said first seal means channel.
