Abstract

A pressure control device is provided for use with a storage container. The pressure control device includes a base defined by a sidewall and a flange extending outwardly from the sidewall, the flange adapted to be connected to a surface of the storage container, the base including a port defined by the sidewall and adapted to be in fluid communication with an interior of the storage container. The pressure control device includes a lid movably coupled to the base to selectively expose the port of the base to an environment surrounding the pressure control device, and a plurality of blind holes formed in a bottom side of the flange of the base. The plurality of blind holes are configured to facilitate connection of the pressure control device to the storage container while preventing leakage from the storage container through the connection, thereby reducing fugitive emissions.
