A traction battery pack may include an outer enclosure assembly. A traction battery pack may include a pressure equalization device received within a wall of the outer enclosure assembly. The pressure equalization device may include a housing and a valve configured to close a gas path through the housing during a battery thermal event of the traction battery pack. The valve may include a spring configured to urge the valve to close during the battery thermal event. The spring is held in place by a spring holder. The spring holder includes a first set of openings spaced-apart from the spring by a first distance, and a second set of openings spaced-apart from the spring by a second distance less than the first distance.
