Abstract: A connecting member and method of attaching the connecting member and a tube member to a housing of a vacuum brake booster is provided. The connecting member includes a cylindrical body portion having a first end and a second end. A rim portion is formed between the first end and the second end, and a stem portion is formed at the second end of the cylindrical body portion. The stem portion includes a tapered end portion to allow the stem portion to flow radially outward when a force is applied to the stem portion. The cylindrical body portion further includes a first opening formed in the cylindrical body portion adjacent to the first end of the cylindrical body portion and a second opening in communication with the first opening. The first opening has a first diameter and the second opening has a second diameter. The second diameter is less than the first diameter. The stem portion is deformed to create a seal between a portion of a housing member and the connecting member.

Abstract: A power booster includes a housing with a rear housing section and a front housing section defining an internal cavity. A housing wall separates the internal cavity into a first chamber and a second chamber with an opening formed in the housing wall, wherein it is desirable to extend a component through the opening. A tube has an end secured in the opening in the housing wall. The tube's end includes a radially directed wall extending from the end of the tube that extends to an axially extending wall positioned concentrically with the tube and terminating with an outwardly turned segment. The axially extending wall is positioned within the opening in the housing wall with a seal positioned between the axially extending wall and the housing wall wherein the distance between the front housing section and the rear housing section is minimized, by extending the component through the tube.
