ABSTRACT:
A multi-ring gasket (140) is for sealing the joint between two flanged general non-metallic pipes. In one embodiment, the gasket has an inner ring (72) an outer ring (132) and a plurality of spokes (77) connecting the inner ring (72) to the outer ring (132). The various gasket embodiments have additional features, including having a substantially in-set outermost ring (132) so that the gasket (140) may be used with a flange having a mating surface interior of the bolts employed to draw the flanges together; having spokes (96) that do not encircle the bolts but that provide for aligning the gasket with respect to the bolts and the flanges; having an outer periphery (102) that is at least partially rectilinear; having one or more peripheral notches (112) for receiving a thickness gauge; and having a tab (144) for manipulating the gasket (140) in the installation thereof.
