Abstract
A device is provided for allowing a conduit to extend through a wall while providing a seal around the conduit. The conduit extends through an opening formed in the wall and the conduit has a first end, a second end, and a central axis extending within the cavity of the conduit and along its length. First and second protrusions of the first end of the conduit are shaped to be received through first and second slots of the opening formed through the wall. A resilient seal member is attached to the first end of the conduit and is compressible by moving the conduit out of a first position relative to the opening in which the first and second protrusions are aligned with the first and second slots. By moving the conduit away from its first position, the resilient seal member is compressed to provide a liquid seal which prevents liquid from leaking through the opening formed through the wall.
