ABSTRACT:
A test fixture for the simultaneous evaluation of a plurality of seals inding an outer tubular shell having a first terminal end and a second terminal end. A first bulkhead has interior and exterior sides to cover the first terminal end of the tubular shell and a second bulkhead has interior and exterior sides to cover the second terminal end of the tubular shell. A sleeve has a first terminal end and a second terminal end and is positioned inside the exterior tube. The sleeve may be segmented into two sections connected end to end. One end of the sleeve is fixed to a simulated pipe flange and sealed by a coaxial overlapping seal. The other end of the flange is connected to an adapted ring by a similar seal. Another such seal is used to connect the two segments of the sleeve.
