Abstract
A resilient gasket is disclosed which includes an annulus of generally U-shaped cross sectional configuration having a circular, arched, radially outwardly positioned base, a first, thin, forward wall extending radially inwardly from the base, a second relatively thick, rearward wall extending radially inwardly from the base, the forward wall and the rearward wall defining a circular, radially inwardly open, retaining ring receiving groove therebetween, the width of the groove being greater than the combined thickneses of the forward and the rearward walls. The forward wall and the rearward wall each terminate radially inwardly in a slanted, forwardly facing lip to facilitate sealing engagement with the spigot end of a section of pipe. The lip of the forward wall serves to center and to wipe the exterior periphery of the spigot end and the lip of the rearward wall serves to seal against the spigot end.
