<p>A multilayer, unitary form-in-place gasket (40) including at least one inner layer of microporous expanded PTFE (421, 42) disposed between a first substantially air impermeable outer layer (43, 46) and a second substantially air impermeable outer layer (43, 46), and a substantially air impermeable region (43, 45) bridging the first and second substantially air impermeable layers (43, 46). The inventive gasket (40) forms a substantially air impermeable seal when compressed at low stress.</p> |
