Abstract

A composite pressure vessel including a fluid port directly through the composite side wall structure formed by internally locating a porting fitting in the side wall structure and then inserting a liner member in the interior of the side wall structure. When thus assembled, a void space is provided between a flange portion on the radial inner end of the porting fitting and the liner member which is completely filled with a sealant. Then a porting hole is drilled through the sealant and liner member from the exterior fitting end. A nut may be threaded onto an exteriorly protruding end portion of the porting fitting and torqued to preload the porting fitting against the composite side wall structure. Also, composite material reinforcement may be applied locally around the protruding end portion (and nut).
