Sorry for earlier post - I assumed there would be a reducer I could use , but there isn't. So, now I'm on the look out for a 32mm OD T piece - any ideas where I can get one - pref in ally, can't find one on google or the brochures I have....

32 x 32 x 32?

Only ones I've seen from CBS are 32 x 32 x 25.

I'm sure someone with a tig can knock you one up from a B&Q aerial pole.

i am just knocking up some 32mm t's in 1mm stainless at the mo. should be getting the welder out today or tomorrow if you want me to knock out another for you? i'm actually using the pipe from an old henry hoover

If you call Bryn @ Alifab, he'll knock you up whatever ali T-Piece you require......

Off a Rover 75 --- the later 1.8 models with the PRT thermostat have a 32mm plastic tee in the top hose
Pretty sure the later 1.8 Freelander 1 will also have it.

Thanks for the posts people - skinned knuckles is making one for me - very forum spirited. I was nearly able to use the Toyota bits I got with the motor but he T was to a cap and after cutting that off it was dangerously short...Thanks all.
