Abstract
The invention concerns a sealing gasket comprising a housing defining a central concavity bordered by two lateral wings, an elastic support housed in the said concavity, a covering presenting a good resistance to wear and a coefficient of low friction which covers over the said concavity and comes back on the lateral wings upon which it comes to be fastened. The invention is applied especially to obturators such as fluid-tight regulator valves.
