1. A torque-limiting cap for an air conditioning service port, comprising:

  • an inner body assembly having a retaining body configured for engagement on the service port;

    an outer body assembly annularly disposed around the inner body assembly and having a first ratchet portion configured for engagement with a second ratchet portion disposed on the inner body assembly;

    wherein torquing of the outer body assembly transmits torque to the inner body assembly from the first ratchet portion to the second ratchet portion to threadably engage the retaining body onto the service port, and wherein at a preset amount of torque resistance, torquing of the outer body assembly causes the first ratchet portion to slip with respect to the second ratchet portion such that no additional torque is transmitted to the inner body assembly.
