A flexible dry sprinkler includes a flexible tube having an inlet attached to a first end, the inlet defining an inlet orifice operatively sealed by an inlet seal assembly. An outlet is attached to the second end of the flexible tube, and defines an outlet orifice operatively sealed by an outlet seal assembly. A flexible linkage extends from the inlet to the outlet through the flexible tube, and is constructed to operatively release the inlet seal assembly responsive to axial translation of the flexible linkage from a first position to a second position. The flexible linkage is supported by the outlet seal assembly in the first position and wherein the flexible linkage is constructed to axially translate toward the outlet when the outlet seal assembly is released.
