ABSTRACT:
A dual or single wall coupling for a fuel line for capturing fluid in the event that leakage occurs at the main coupling and/or the primary tube comprising a lightweight slidable sleeve element shrouding the primary coupling engaging on its inner diameter axially spaced radial seals. The sleeve assembly permits the utilization of commercially available standard couplings and eliminates the tedious assembly techniques required that were necessary heretofore.
