SECURED COUPLING ASSEMBLY AND METHOD OF PREVENTING LOOSENING

摘要

A coupling assembly (10) includes a first coupling member (16), a second coupling member (18), and a coupling nut (36) disposed over a portion of the second coupling member (18) and threadingly engaging the first coupling member (16) to retain the first and second coupling members together. An insulation blanket (46) encloses the coupling nut (36), and a retention strip (80) having a first end (82) attached to an inner surface of the insulation blanket (46) and a second end (84) attached to the coupling nut (36) is provided to prevent loosening of the coupling nut (36).
