These heavy duty channel profiles can seal against high differential pressures, but the sealing gap must be relatively small. Four styles are readily available within the series - the "X"mesa-top profile, the "QB" square beaded profile, the "AB" angled bead profile, and the new, patent pending "SR" self-retaining style which can be installed without the use of adhesives. Axial, and radial expansion in/out configurations are common for this series.
