When testing the thread inserts or when removing and replacing the port retainer it is crucial that the KMDSI recommended torque specs be followed when tightening the port retainer screws. Any over torque of a screw greater than 12 inch pounds can result in serious damage to the surrounding fiber glass in the port area. This can lead to loosening of the port retainer and in extreme instances to flooding of the mask.

WARNING: Do not attempt to install new thread inserts in the mask frame for the port retainer screws by yourself. If the installation is done improperly the port retainer can come loose and the mask could flood resulting in drowning. Fiberglass and insert repairs should be only be completed by technicians specifically trained and certified in these procedures.
