The invention provides a multi-layer gasket seal. The gasket seal includes a sheet having a first sheet surface. An aperture pierces the first sheet surface. A first channel is defined in the first sheet surface and extends along a first path around the aperture. The first channel has a depth and a width. The gasket seal also includes a ring seal disposed in the first channel. The ring seal has a thickness defined between a sealing surface facing away from the channel and an opposing surface facing the channel. One of the thickness and the depth varies about the aperture such that a distance between the sealing surface and the first sheet surface varies about the aperture.
