Lawrence, I may have misunderstood you here. No problem connecting the 32mm (or even 21.5mm) pipe to the boss. The problem is that standard plastic soil pipe is rather larger diameter than cast iron. Hence the boss won't clamp on to it very well. Even if there's enough adjustment range when tightening the strap the flange likely won't sit very well on the soil pipe. The strap tightening problem can be solved by carefully placed packing. The flange seating looks like a bodge with silicone.
