Abstract
The present invention is directed to an annular gasket for providing a fluid-tight seal between an inner pipe and an outer pipe, when the pipes are in a relative surrounded and surrounding relationship. The gasket includes a gasket portion configured to sealingly engage the inner and outer pipes when the pipes are in a relative surrounded and surrounding relationship. The gasket includes a low coefficient of friction surface which is applied to the gasket portion. The gasket may be formed by a method in which a low coefficient of friction film is inserted into a mold before injection of compounds used to form the gasket.
