ABSTRACT:
An hydraulic chip breaking tool holder is provided with a fluid coupler and seal assembly for transferring high pressure, chip breaking fluid from an outlet opening of the main body of the tool holder to an inlet opening of an attached nozzle cap. A coupler in the form of a dowel is interconnected between the openings. At least one of the openings includes a seal cavity having an outer wall. The dowel is inserted through the seal cavity. A deformable pressure sensitive seal is disposed within the seal cavity and extends around the dowel. The pressure of fluid passing through the tool holder causes the seal to radially expand and seal the area between the dowel and the outer wall of the seal cavity, thereby preventing fluid from escaping pst the seal.
