ABSTRACT:
To connect an external fuel line to an internal fuel line feeding an internal fuel manifold in a combustor of a gas turbine engine, a fitting includes a first joint half terminating the internal fuel line and a second joint half terminating the external fuel line; the joint halves being united to provide a threaded fluid joint. The first joint half is integrally formed with a cup-shaped reservoir containing the fluid joint and having an outwardly turned brim which is affixed to a combustor casing in surrounding relation to a casing hole. The reservoir thus serves to shunt mechanical loadings from the fluid joint and to collect any fuel leakage therefrom.
