Abstract
A sealing gasket for a ventilation duct system includes an annular gasket body and a pair of annular sealing flanges extending radially outwardly from the gasket body. The sealing gasket has, in axial cross-section, a generally flat top wall and a curved or, alternatively, a radiused bottom wall. One of the sealing flanges is positioned adjacent one circumferential edge of the sealing gasket and the other sealing flange is positioned axially spaced from or offset from the opposite circumferential edge of the sealing gasket. The sealing gasket is provided to form a generally air-tight seal between overlapping ends of first and second components of a ventilation duct system.
Claims52
A sealing gasket configured to form a seal between overlapping ends of first and second components of a ventilation duct system, comprising:
- an annular gasket body configured to be disposed about one end of the first duct component, the gasket body having, in cross-section, a generally flat top wall, a radiused bottom wall and a pair of opposite circumferential edges;
- a first annular sealing flange extending radially outwardly from and generally perpendicular to the top wall and positioned adjacent one of the circumferential edges;
- and
- a second annular sealing flange extending radially outwardly from and generally perpendicular to the top wall and positioned axially spaced from the opposite circumferential edge.

- a first annular sealing flange extending radially outwardly from the top wall and positioned adjacent one of the circumferential edges, the first sealing flange having a pair of generally parallel side walls;
- and
- a second annular sealing flange extending radially outwardly from the top wall and positioned axially spaced from the opposite circumferential edge, the second sealing flange having a pair of generally parallel side walls.
