A connection system for exhaust gas recirculation (EGR) in a diesel engine has an EGR conduit, an exhaust manifold, and a sealing strand. The EGR conduit forms a first surface surrounding an inlet. The exhaust manifold forms a second surface surrounding an outlet. The sealing strand is disposed in a groove formed by one of the first and second surfaces. The groove has an inside surface. The first and second surfaces are pressed together to form a first seal. One of the first and second surfaces compresses the sealing strand against the inside surface to form a second seal. One of the first and second surfaces may be a convex surface. The other surface may be a concave surface.
