Hi I am having a dilema

 

I have this drain:

 

The shortend section screws on to the base but is of a different countries orgin and is made of stainless . I need to make a brass interface to this and wonder if i cut it shorter to the tube i would have better luck with a seal?

does anyone have any ideas how to get a good seal?

Not clear what you are connecting to what and which bit needs sealing. Plumbers boss-white would be the traditional sealant.

Just bin it and get one with 1.5" BSP thread to fit UK and european traps only cost a few quid. I've thrown a few sink and shower wastes away that are non standard as it's not worth the hastle.

i want to end up about 22mm

[Martin NewboldParticipant @martinnewbold]

I have heard that brazing with heat can remove stainless properties so i am looking for alternatives. The outside is 32mm

In that case still do what I said and use a central eating pump connector which will screw onto a 1.5" waste and have a 22mm compression fitting on the other end.

[Martin NewboldParticipant @martinnewbold]

its 32mm Jason

Get standard sink waste plumbing fittings.

32mm is 1¼"

You can get adaptors to go from 32mm plastic to 22mm.

Use Plumbers Mait to seal waste fittings to sink outlet.

the other end i think it screws on to is 46mm 12 tpi

its on a lathe will boss white stand up to cutting fluid? I would rather bin this part and connect onto threaded bigger thread which is around 46mm  x 12tpi i think that makes it 1 7/8"

Are you sure it is not about 47 x 11tpi as that would make it 1.5" BSP. As the thread has been rolled onto the stainless it is likely to be less than the text book major diameter.

[Martin NewboldParticipant @martinnewbold]

Not really no Jason its 1.5" BSP as it seems to small if that 1.5" .

If i put a vernier gauge across bottom of bigger part male its 45.75. This is the lower profile in the dips of the thread and will just push into other part without going into threads
