Abstract
A device for sealing a projectile guiding kit may be used with any kit having a rear unit and a front unit rotatably connectable to the rear unit thereof. The device may include an annular body adapted to envelope at least a front portion of the rear unit and at least a rear portion of the front unit of the kit. The device may include a flexible ring-shaped strip attached to an inner side and at a front end of the annular body and adapted to seal a gap between the rear unit and the front unit of the kit. The annular body may be adapted to slide towards the rear unit of the kit when subjected to a longitudinal acceleration that exceeds a predetermined acceleration value, thereby uncovering the gap and enabling uninterrupted rotation of the front unit with respect to the rear unit of the kit.
