The first end has a first opening, and the second end has a second opening that fluidly communicates with the first opening to define a bore. The wall includes an inner curved second and an outer curved section that includes an indentation. The indentation includes a first inwardly extending part and a second inwardly extending part. The second inwardly extending part includes a through hole having an inner opening and an outer opening. The inner opening is located between the outer opening and the second opening. A diameter of the outer opening is less than a diameter of the inner opening. A thickness of the second inwardly extending part is less than the diameter of the outer opening.
