a majority of the annular body 106 and abuts the second flange 110 the seal member 122 can be coupled to or integrally formed with the body portion 120 and can sealingly engage the second surface 66 of the boss 60 in the particular example provided the seal member 122 is an annular lip the coupling portion 124 can extend from the body portion 120 on a side opposite the second flange 110 the coupling portion 124 can define an annular gripping surface 130 that can frictionally engage the first surface 64 of the boss 60 the coupling portion 124 can extend from the body portion 120 in a direction generally parallel to a longitudinal axis of the boss 60 the coupling portion 124 can extend coaxially with the annular body 106 and can be disposed onto or over the first flange 108 it will be appreciated that the chamfer 72 on the corner between the first and second surfaces 64 and 66 can aid installation of the coupling portion 124 onto the first surface 64 when the static tube 38 is installed to the housing 34 it will also be appreciated that the chamfer 72 on the corner between the second surface 66 and the axial end face 70 of the boss 60 can aid installation of the seal member 122 onto the second surface 66 it will be further appreciated that the first flange 108 can be employed as a u201c stop u201d which can be employed to position the seal member 122 relative to the static tube 38 in a desired location and or as a flange against which tooling can be abutted when the first seal 48 is.
