I could do with a decent expansion bottle. The way my (car) plumbing works, I need a traditional expansion bottle just with single inlet/outlet (so either bottom connection or top connection with tube to bottom of tank inside) and an overflow. The only complication is that I only want 8mm connections.
Any suggestions gratefully received.
Many thanks
ETA - I know that there are bike ones that fit the bill but I want one that looks like it should be there rather than one shaped to fit various nooks and crannies behind a fairing.

Hi
I am using a VW one, think its either
Polo or Golf. Only cost £11 brand new from my local supplier.
The outlet is bigger than 8mm though, poss 12mm. you should be able to sleeve though.
Also the Vauxhall Corsa is similar.
It may have a smaller outlet as well,
I cant remember

VW bottle

how about using a new type mr2 one, think the outlet hole is close to 8mm as i was going to use it but ended up using a clio one as the outlet hole was a similar size to the inlet of the head. its a decent size too .

Suzuki swifts used to have a nice plain rectangular bottle about 5"x4"x3", rover 200 series had one pretty similar too, quite a few Japanese cars still use traditional rads with a pressure cap and expansion bottle rather than header tank with the pressure cap.

contact deneo on here he knock you one up any size you like

I'll second Tom on that. Dene made one for me, welding is first class.

I think this is a traditional type.

I replaced this with an ally one one my car.
It has a single 8mm inlet at the bottom that pipes from the highest point on the engine,
in my case the thermostat housing. (expands into tank, sucks back on cooling)
It has a conventional rad cap with an 8mm overflow connection.

7" x 5" x 3"
Needs a clean up. Postage + a pint.
