摘要:
A torque-limiting cap (100) for an air conditioning service port (14) includes an inner body assembly (122) having a retaining body (116) configured for engagement on the service port, and an outer body assembly (134) annularly disposed around the inner body assembly. The outer body assembly (134) has a first ratchet portion (140) configured for engagement with a second ratchet portion (146) that is disposed on the inner body assembly (122). When the outer body assembly (134) is torqued, the outer body assembly transmits the torque to the inner body assembly (122) from the first ratchet portion (140) to the second ratchet portion (146) to threadably engage the retaining body (116) onto the service port (14). When there is a preset amount of torque resistance, the first ratchet portion (140) slips with respect to the second ratchet portion (146) such that no additional torque is transmitted to the inner body assembly (122) from the outer body assembly (134).
