Pressure Cartridges have their greatest utility generating high rates of pressure force for a short period of time. Displacement devices such as pin pullers, normally open or closed valves, thruster and separation bolts utilize this device. In several ejection seats pressure cartridges are utilized as an initiator for propellant charges. Pressure cartridges are adaptable to the requirements of your system for different pressure output to accomplish specific events. Our 103377 series has over 400 variations utilized in a wide range of aerospace and defense platforms. Our 817444 series cartridge has become a standard within the ejection seat community to initiate other explosive devices because of its high reliability and robust design.
