This document has as main objective to verify the sealing of a robot explorer dedicated to inspection tasks of plumbing pipes. For this, redesigned packages, simulations and laboratory tests were carried out in order to ensure IP68 protection according to IEC60529. The experimental tests were based on the submission of the robot to dust and water, concluding that the mechanism has an IP65 degree of tightness (resistant to dust and low pressure jets). In addition, it was observed that the tightness is closely related to the quality of the machining and the seals, so a second phase is projected that can improve the robustness of the system until an IP68 certification.
