Abstract: A sealing grommet, particularly for data centers and the like, formed of one or a pair of U-shaped frame sections, each co-molded with a thermoplastic elastomeric seal of corrugated wave form, with corrugated edges of the seals exposed at the open sides of the U-shaped frames. A pair of such grommet sections joined together, with the corrugated edges arranged to be in contact and in phase, provides a uniquely efficient seal to hold back air under pressure while allowing various pass-through elements, such as cables, hoses, etc., to be extended through the grommet and while enabling the pass-through elements to be easily added, removed, or rearranged as may be necessary to accommodate the dynamic changes experienced in the operation of a data center.
