Xantia Pressure Regulator O Ring size?

[romie]

Heya,
I'm going to be replacing the O rings in my pressure regulator due to leaks. (Xantia 1.9TD 1996)
I've found the very helpful image from VertVega and the notes on one of the sizes, (29mm x 2.7-3mm).

From the below picture and the O ring arrowed with a '?'
Anyone know what this other O ring size is?

Many thanks, romie

I don't know if there is a gasket in-between the plastic 'hat' and the housing as shown in below picture.
I'll get some gasket material from ebay, say 0.8mm thick.

Anyone come across a gasket here?



Cheers, romie

Thanks Malcolm, think I might have the o ring size mixed up on the picture then.

Just trying to figure out what the numbers mean in the o ring measurements..
So right o ring is 37X33X1,9 which is 1.9mm cross section... with 33mm inside diameter and 37mm is outside diameter (I.D + 2xCrossSection~ish)?
And left o ring is TOR C 29 T2,7 which is 2.7mm cross section with 29mm inside diameter? No ideas on the TOR reference? :/

Would they both be a round, circular cross section, not a flat, oblong cross section like with the sphere o rings?

hmm, bit confused here.

Reason for questioning is I might be able to find nitrile o rings at a fraction of cost and they could be delivered!

And there's no fibre gasket between the plastic 'hat' no? I'm getting some gasket fibre material in just in case.

Sorry for the follow up thoughts.. In the meantime I'll ask Citroen if they have any to order.

Thanks for replying and looking that up!!

the one on the right is definitely a round profile cross section,

i would think the other one is also but i have not delved into a regulator that far as yet,

speak to Martin at Pleiades on
01487 831239
as he reconditions citroen hydraulic components and if he has the seals he will usually sell them to you

Right'o, thanks Malcom
