Attache bottle trap to waste

[bandejapaisa]

I'm trying to install a Crosswater Bottle trap:

Here is the specification with dimensions.

Here are the installation instructions:

The chrome pipe that should connect to my waste outlet is 35mm. Can someone please send me a link to a part that I'm supposed to use to connect this to my waste? I can't find anything on screw fix that I need.

Thanks

I normally use an inch and a quarter compression elbow in the wall to connect the chrome waste.

I have just used a normal 1 14" (32mm) comp elbow in the past for chrome wastes there is a fair bit of adjust-ability in compression fitting.

I see. So I could use this then:

Because I ended up buying a load of 40mm pipe and fittings, so I might as well use them instead of swapping them all for 32mm stuff.
