A low profile joint is provided for a strut tube extending radially through a strut extending between an outer casing and an inner hub in a gas turbine engine frame. The strut tube has a longitudinal axis and a closed distal end. A sideseat is spaced from the distal end and is disposed substantially perpendicularly to the longitudinal axis to define a flow orifice. A secondary tube has a ballnose at a distal end thereof disposed in abutting contact with the sideseat for channeling fluid therebetween. A fastener joins together the strut and secondary tubes in compression between the ballnose and sideseat to maintain sealed contact therebetween for channeling fluid between the strut and secondary tubes.

[ We claim:] [1.] A gas turbine engine frame comprising:an outer casing;a hub disposed coaxially with said casing and spaced radially inwardly therefrom;a plurality of circumferentially spaced apart, hollow struts extending radially between said casing and hub and defining therebetween a flowpath for channeling engine gases;an elongate strut tube having a longitudinal axis, and extending radially through a first one of said struts;said strut tube having a closed distal end, and an annular sideseat spaced radially from said distal end and disposed substantially perpendicularly to said longitudinal axis to define a flow orifice;a secondary tube having a ballnose at a distal end thereof disposed in abutting contact with said sideseat for channeling fluid therethrough; anda fastener joining together said strut and secondary tubes in compression between said ballnose and sideseat to maintain sealed contact therebetween and defining a fluid joint for channeling said fluid between said strut and secondary tubes.
