Full connection occurs when the torque sleeve moves forward and locks on the mating nipple half tangs. To uncouple, pull back on torque sleeve to disengage lock, and unthread coupler. Thread-lok couplings provide today's aerospace fluid handling systems with quick disconnect capability, self-sealing action and visual/touch indication of a fully coupled position. Thread-lok couplings offer simple one hand operation and reliable performance for use during the maintenance of fluid handling systems. The thread-together coupling provides the mechanical advantage required for coupling under higher pressures.
