Abstract
Apparatus for testing the bond strength of materials comprising a housing having a cavity, an extrudable fluid seal received in the cavity, and a passage for placing the fluid seal in communication with a source of pressurized fluid. A material is attached to a fastener associated with the housing, coaxial with the housing's longitudinal axis. The fastener, the material being tested, and the extrusion boundary of the fluid seal are independent of the pressurized fluid applied to the fluid seal.
