摘要： A fluid duct (22) has a plastic body (27) with a forward cylindrical portion (117) having an outer periphery and a rear cylindrical portion (118) having an outer periphery. The forward and rear cylindrical portions (117, 118) are at equal radial distances from a center line of the duct. A bead (28) is formed on an outer periphery of the duct body (27) intermediate the forward and rear cylindrical portions (117, 118). The bead (28) has a radially outermost first distance (d 1 ) measured perpendicularly away from the outer periphery of the forward cylindrical portion (117). A second distance (d 2 ) is defined between a forward end (29) of the duct body (27) to a rearmost end of the bead (28). The ratio of the first distance (d 1 ) to the second distance (d 2 ) is between .200 and .270.
