System and method of retaining a component in a hydraulic control unit housing

The present invention relates to retaining components in a housing. In particular, the invention is directed to a system, such as a hydraulic control unit, wherein an attenuator cap is contained within an opening of the unit housing by seating the cap against an angled stop in the bore of the unit and deforming a portion of the housing over the cap. A system, device, and method for retaining a component within a hydraulic control unit of a vehicular braking system. The system comprises a housing and a component wherein the housing includes an angled lead in formed in an opening of the housing and an outer retaining portion. The component includes an inner portion that is angled to contact the angled lead in at a single point. The component includes an outer portion to contact the retaining portion of the housing when deformed. A deformed portion of the housing retains a device, such as the component.
