An apparatus for smoking combustible material can include a glass tube having an axis and open ends. The apparatus can have a rod axially coupled to the glass tube. In addition, a grommet formed from an elastic material can be included. Examples of the grommet can have a tube end to axially receive the glass tube in an interior of the grommet. A shoulder can be located in the interior of the grommet to abut one of the open ends of the glass tube. The grommet can further include a rod end to receive and frictionally engage a portion of the rod and permit relative motion between the rod and the grommet. In addition, the grommet can have an external annular recess located between the tube end and the rod end.
