Filler neck

[Dutch Paul]

Anybody know where I can get a radiator filler neck to weld on a stainless expansion tank?
All I can find are aluminiun ones - I`m looking for stainless if possible.

My stainless expansion has a brass neck welded/ soldered to it, another option ?

Thanks guys

Looks like brass then.
Does anyone know if you can silver solder brass to stainless?

HI Paul,

We sell them here at www.shinybitz.co.uk ( got your e-mail)

Also the caps.

Stainless can be soldered to brass in two ways.

Both methods use silver solder ( not the stuff you get from electrical shops) with a high silver content. This is quite expensive stuff.

You will also need some flux ( again specially for st/st) This can also be expensive as you can only buy it in 500g tubs ( if using hi temp) This can cost as much as £20-£40 depending on where you buy it. The rods can be £3- £10 ( depending on method used)

Remember to thoughly clean your parts. Acetone is a good cleaner.

The stainless would benifit from a good clean with amonia as this helps with the flow.

Also remember ( if using high temp) do not "burn" the st/st as you will have to take apart and start again.

I would do a few practice runs to be save.

If you need any further help give me a bell 07720713885 or drop me a mail.

Hi Roger,

Did you say that you do stainless radiator filler necks? Because I need a top 11/2 stainless water pipe made up with a filler neck. I have an alley on which looks naff.
