How are individual harness adjustment straps attached to the MBU-12/P oxygen mask?

The individual harness adjustment straps of the MBU-12/P oxygen mask are attached using capped tee nuts and a self-locking screw. This method provides a secure and reliable attachment mechanism that ensures the straps remain firmly in place during use. Capped tee nuts offer a broad support base that helps distribute pressure, reducing wear and potential failure points in the harness system. The incorporation of a self-locking screw further enhances safety by preventing accidental loosening, which is critical for maintaining the integrity of the oxygen mask during high-stress flight conditions. Proper adjustment and secure attachment of the harness are essential for optimal performance and comfort, making this method ideal for aircrew flight equipment.
