<p>A coupling assembly including a coupling comprising an elongate member (300) with a fluid passageway (304) through it and a tapered end section (306) on the elongate member, a grommet-receiving section (308) disposed intermediate of the tapered end section and a second section of the coupling spaced apart from the tapered end section and a grommet (200) comprising an intermediate section(201) with an outer surface, an inner surface (202) and first (204) and second (206) radially extending end sections, the coupling being insertable into the grommet and the grommet being configured for receipt onto the grommet-receiving section. The coupling assembly can be inserted into, or removed from, an opening in a wall structure (400) by hand, without using any tools. When a fluid-tight connection has been formed by inserting the coupling assembly into the opening in the wall structure, the coupling assembly can be tilted at an angle while the fluid-tight connection is maintained.</p> |
