A flexible dry sprinkler includes a flexible tube having a first end and a second end, an inlet, an inlet seal assembly, and an inlet release unit. An outlet is attached to the second end of the flexible tube, and is sealed by an outlet seal assembly. A flexible linkage extends between the inlet and the outlet through the flexible tube. When the outlet seal assembly is released, the flexible linkage translates from a first position to a second position, and the flexible linkage operates the inlet release unit to release the inlet seal assembly.
