Modification of widely used pressure-assisted gasket ensures tight seal even when one sealed surface somewhat rough or porous. Modified U-cross-section gasket has thin lips increasing sealing area and conform to slightly rough surface. Lips provide wider sealing area and extend highly loaded region at tip. Coating of polytetrafluoroethylene on tip and lip augments conformance.
