A self energizing pipe gasket includes a base and arm configuration projecting therefrom which cooperates with the base when pipe sections are assembled to cause the lip or sealing edge of the arm to kick away or distend toward the sealing surface of the pipe. To facilitate this action a harder insert is provided in the base in the form of a reinforcing ring providing a less compressible surface for the arm to react against. The ring also stiffens the gasket making it more difficult to dislodge upon assembly of the pipe sections enabling higher compression forces and assuring that the gasket does not go under or below the minimal compression requirements to form a sound flexible yet fluid tight seal.

A gasket comprising a compressible base adapted to be received by one of a pair of telescoping pipes, an arm connected with and extending from said base and terminating in a sealing lip which curves away from said base and is adapted to engage the other of the pipes, said base having a surface adapted to engage said arm between said connection with said base and said lip upon telescoping of the pipes together to press said lip against the other of said pipes and reinforcing means in said base to reduce the compressibility of said base in the area of said surface.
