摘要

An apparatus and method for attaching a tube member to a housing of a vacuum brake booster is provided. A tube member includes a body portion, an outer surface, a first end, and a second end. A first collar portion is disposed between the first end and the body portion, and extends outward from the outer surface. A lip portion is disposed at the first end and extends outward from the outer surface. The first collar portion and the lip portion define a recess to receive a first housing member. The tube member may further include a second collar portion spaced apart from the first collar portion and extending outward from the outer surface. The second collar portion may preferably define a contact surface for contacting an inner surface of a second housing member.
