Anyone know a source of the same thing for plastic conduit please? (I
know TLC do reducers but they seem just to join 25mm to 20mm conduit
whereas I'd much rather just have something to lock 25mm into a 20mm
hole.)

Bugger. Just realised that doesn't give you a 20mm *hole*, only a 20mm
thread to fit a 20mm hole. Sorry.
