McAlpine Mechanical Pipe Boss Connector Black 40mm
Before taking it home and unpacking I couldn't figure out how it worked. Now, having fitted it, it couldn't be easier. Brilliantly clever bit of kit. You need to cut a hole 56mm wide in your soil pipe and this slips in flush to the pipe then expands on the reverse with a special 'key' (supplied) you twist on the outside. Ten seconds later you've a watertight coupling and a 40mm compression inlet ready to take your Floplast pipe or whatever. No adhesive, no straps, no messing.

Not as good as I thought
Read the reviews so I purchased one not as good as I would of liked it drilled hole with holesaw 57mm went in easy too easy tighten up couldn't get it any tighter and it came out retried and it was slightly better perhaps I should of brought one for a smaller pipe

simple to use
a 57 mm hole is OK but 56 would be better, at 57mm the pipe can easily be dislodged - do 56, see if it's tight, if not you can easily file / sand a little away, but not much you can do apart from silicone if its too big!
