Their exclusive 6.4 mm neoprene o-ring and ABS latches seal perfectly and includes an automatic purge valve for quick equalization after changes in atmospheric pressure. Your equipment can fit into the high density foam of these cases for total subjection and protection against impact, vibration or shock.
