<p>A connector seal comprises a ring (14) adapted to be a push fit in a hole (2), one or more circumferentially extending inwardly directed ribs (7) within the ring adapted to engage and seal with the outer surface (5) of a pipe (3) inserted through the ring, and a collar (6) around the outside of the ring adapted to abut against a wall (1) in which the hole (2) is formed as the ring is inserted therein, the collar (6) being composed of a harder, less flexible material that the ring (4) and ribs (7). Additionally, a radially inwardly directed annular flange (8) on the ring (4) at its leading end as inserted into the hole (2), the flange serving as a stop against which the end of the pipe can abut. Preferably, this stop flange (8) is also composed of a harder material than the ring (4) and ribs (7) and may be the same material as the collar (6).</p> |
