Abstract: A seal system is provided. The seal system may comprise a first duct 14a, 190having an annular geometry, a second duct 14b overlapping the first duct in a radial direction, and a seal disposed between the first duct and the second duct. The seal may comprise a groove 168 defined by the first duct and a piston configured to slideably engage the groove 168.
