ABSTRACT:
A connector is described which can be easily installed in a hole of a barrier wall, which assures tight sealing when there is a substantial pressure difference on opposite sides of the wall, and which avoids set of the sealing material. The connector includes a frame with a radially inner portion and with a skirt extending around the inner portion and slightly bendable radially outward and inward. O-rings are mounted on the outside of the skirt, so when pressure causes the skirt to expand, the O-rings form a tight fit against the surface of the hole, while when pressure is relieved the seals are pressed with less force and avoid becoming set. A group of thin limiters extend between the skirt and the inner frame portion. The limiters allow the skirt to expand radially outwardly, but limit radially inward deflection of the skirt to assure that even when there is no pressure the O-rings push firmly against the hole surface.
