The second tubular portion is inserted inside the body and the first tubular portion is inserted so that the first tubular portion extends from an exterior of the body to inside the body. The second tubular portion expands to increase the cross-sectional area of the second passage in the second tubular portion while the second tubular portion is inside the body. The cross-sectional area of the first passage in the first tubular portion is maintained. The first tubular portion has a first thickness and the second tubular portion has a second thickness different than the first thickness.
