An anti-extrusion ring for use in conjunction with a vehicle solenoid valve has a plano-concave cross-section. The anti-extrusion ring is used to support a seal that seals the interface between a solenoid valve and a bore within a valve fitting. When the solenoid valve is installed in the valve fitting, a bore-to-ring interference area is formed between the bore and the anti-extrusion ring and a debris capture area is formed above the bore-to-ring interference area. Thus, when the anti-extrusion ring controllably fractures during installation of the solenoid valve with the bore or due to vibration, debris from the ring will be captured in the debris capture area and prevented from entering a fluid system in which the vehicle solenoid valve is used. Moreover, the anti-extrusion ring deforms in a such a manner that accounts for the accumulation of the manufacturing tolerances of the solenoid valve and its corresponding fitting and in such a manner that allows the solenoid valve to maintain its center and proper alignment within its corresponding fitting. As such, extrusion of the "O" ring is reduced or eliminated.
