what do I need for this?
- Thread starter gazebo
- Start date
A universal compression fitting should fit both the copper and plastic.

I hope you intend connecting the nominal 1-1/4" copper to the 1-1/2 plastic rather than the other way round, as reducing the diameter as you go downstream is not a good idea. It could make the outlet slow to drain, prone to blockages and induce syphonage of the trap.
35mm OD is a nominal 1-1/4" bore, that's about 2/3 the cross section of 40mm or nominal 1-1/2" bore.
Edited to clarify nominal sizes.

thank you for that info
it is going from the 35mm copper to the 40 mm plastic, with the plastic being the drainage. The 35mm copper is the outlet for the waste on the object that needs the drainage (which is a pasta boiler in a kitchen)
many thanks
