ABSTRACT:
A stackable self-aligning and self-sealing plastic spacer for extending a soil pipe flange to floor level to meet a toilet fixture has a ring-shaped spacer with a tapered inner collar protruding from its surface. The collar is received within the similarly tapered central opening of the next adjoining spacer. The spacers are made of resilient plastic to provide a wedging fit that seals the joint against leakage.
