An investigation was undertaken to demonstrate an analytical leakage- prediction correlation technique for comparison with actual test results received in the evaluation of the standard AN flared tube connector. Success of this approach would allow the use of this prediction correlation technique on other connector concepts. A secondary objective was to evaluate the performance of the AN flared tube connector. The approach consisted of deriving an analytical leakage-prediction technique using a flow conductance parameter in conjunction with the Meyer hardness index and comparing these data with the test results received from the evaluation of the flared tube connector. The program did not achieve satisfactory prediction correlation between predicted and test results. However, comparison of predicted results with the test results did show the predicted leakage performance values to be extremely conservative. The evaluation of the flared connectors did demonstrate a .000001 atm ccsec helium leakage capability of the flared connectors when tested under specific operating conditions.
