A thermal actuator and component part wherein the guide tube of the thermal actuator is integral with the component part. The cup containing the thermally responsive wax is crimped over a flange on the end of the guide tube. An actuating piston is positioned in the guide tube. The component part has a portion having a larger external diameter than the external diameter of the cup. The thermal actuator and component part are assembled by enclosing a split die member about the component part and integral guide tube member, placing the split die member with the component part and tube member into a lower tool member and advancing an upper tool member containing the cup toward the die member to cause the wall of the cup member to be crimped around the flange.
