The present disclosure involves an improvement in the method of forming a labyrinth seal which has an outer member comprising a hollow cylindrical housing containing a plurality of stacked annular first plates positioned apart by means of annular first spacers. An inner member is provided which comprises a plurality of stacked annular second plates which interleave with the first plates and are positioned apart by means of second annular spacers. The improvement comprises the provision of a hollow housing with a first cover affixed thereto and with the axial length of the housing being sufficient to permit the upper portion to be bent over to form a flange. An inner cylindrical support member is inserted into the hollow in the housing. The first and second plates and spacers are then stacked in the housing and the first plates interleave with the second plates of the inner member. The upper portion of the housing and the upper portion of the support member are then bent over to position the first and second plates and the first and second spacers in the housing.
