This gasket is a direct replacement for the 4" Cherne "Original", End of Pipe Gripper Mechanical Plug seal that serves as the blackwater tank stopper on Prevost Class A Motorcoaches. Saves you money by reusing the existing plastic and metal parts. Other places you may find this seal is with drain, water, and vent applications.
