Flexible Pipe Connectors, Rubber Couplings
Will the 1-1/2" x 1-1/2" trap adapter work for this appliion?" A. These trap adapter flexible couplings are so flexible they will usually tighten down one or 2 sizes more than the pipes shown that they fit, but we would suggest you use a coupling closer to the actual size you need which in this case would be the 1-1/2" x 1-1/4" coupling.
