Abstract
A gas strut includes a housing, a piston assembly, a dye, and a dye containment seal. The housing includes an inner surface defining a chamber extending along a centerline. The chamber includes a working portion and a dye storage portion disposed axially adjacent to the working portion. The piston assembly is constructed and arranged to reciprocate within the working portion, and the dye is located in the dye storage portion. The dye containment seal is disposed in the dye storage portion, and is constructed and arranged to transfigure from a normal state to a dye release state thereby releasing the dye upon the piston assembly.
