  • Patent number: 4664428
    Abstract: A pipe joint includes a novel sealing plate for sealing the axial joint or joints of a cylindrical coupling. The sealing plate carries on its upper surface a pair of axial gaskets which seal against the coupling above the sealing plate and against O-rings on the pipe sections below the sealing plate. In an alternate embodiment, the axial gaskets can be adhered to the inner surface of the coupling so as to engage the edges of the sealing plate. In another embodiment, in lieu of a separate sealing plate, one end of the coupling can carry a single axial gasket and be lapped under the other end of the coupling to form the axial seal. The sealing assemblies of the invention ar particularly useful in situations in which the pipe ends are subject to movement.
