The larger side is the side that you insert the pipe into. Whether that be inside or out is up to you.

as i understand it, you want the flat side on the side that will be under pressure. i think this generally means inside. You want the pressure to push the uniseal to work better, rather than constantly pushing the uniseal away (if that makes sense). If there is no pressure, then it's whatever way is easiest.

On my fish tank I have the "flat side" on the outside.

For the stand pipe in the grow bed I have the "flat side" facing up and have pushed the stand pipe down from the top (hope that description can be understood)

No leaks or problems what so ever.

Their website wouldn't tell you anyway....

Pretty much all of the ones we have used were with the flat side on the outside, because that is where we were inserting the pipe from..

Uniseals are rated to deal with negative Pressure. Ie pressure is on the outside. Uniseals instructions say that the larger deride is where the penetrating pipe is inserted from. If it is as Silkcom has suggested then the larger side would be on the outside when used in siphons but on the inside of pipe to pipe pressurised systems. This would mean that the pipe would need to be inserted from inside the pipe which is clearly not posible with a rigid pipe.
