Inlet stub O ring sizes

[martymoose]

Hi guys,

Putting new inlet stubs on a 1976 Jota, I have bought O rings with a 3.5mm section, I measured the old ones at 3.2mm, but they are fairly old and squashed.  3.5mm seems a little too big?  What size should I use?

Cheers

Marty

Marty,
I use BS130 Viton
That is the part number, any bearing shop will recognize it

Thanks guys,

Brian's Jota, original ones had been broken and welded back up, sorta turned them into bananas!  He had new stubs, so will set them up with new O rings.

Cheers
