Moeller Click-Loc™ Self-Locking Fittings

Our Click-Loc™ design is used to secure critical fluid fittings in a variety of aerospace applications including commercial and military aircraft engines. The "no-lockwire" design greatly improves maintainability and reduces maintenance cycle time. Click-Loc™ also improves reliability because it eliminates the "wired-but-finger-loose" failure mode and it completely prevents coupling nut backoff from any known cause. Laboratory and engine qualification testing has shown conclusively the Click-Loc™ is not loosened by vibration, thermal cycling, pressure pulsation, tube/hose torsion, sonic effects, or any combination thereof.
