A combustor-to-transition seal ( 301 ) includes a spring clip assembly ( 322, 422, 522 ) and a first spring metal ring ( 340, 441 ) or a ring assembly ( 440,540 ) that includes the first spring metal ring ( 441 ) and a second spring metal ring ( 442 ). Such combustor-to-transition seal ( 301 ) provides a first seal ( 321 ) and a second seal ( 331, 531 ) when at a junction of a combustor ( 108, 308, 508 ) and a transition ( 114, 314, 514 ). In an embodiment, the first spring metal ring ( 340 ) has a plurality of apertures ( 342 ) through the ring ( 340 ) that provide effusion cooling of the ring ( 340 ). The plurality of apertures ( 342 ) regulates a flow of cooling fluid to maintain an acceptable temperature of the ring ( 340 ). In an alternative embodiment, the second spring metal ring ( 442 ) has grooves ( 446 ) that regulate a flow of cooling fluid to maintain an acceptable temperature of the ring assembly ( 440 ).
