Water rail O rings

[S3THUNDER]

Hi,
I'm about to fit new stainless steel water rails,but I need to replace the old O rings. Are they the common nitrile type? TVR parts are charging over £1:00 each, so I was wondering if they are over charging or they are made of a different type of material.

Thanks Mark

I have used Nitrile for the intake O rings and injector seals, as they are good for 120C. I reckon if I manage to damage them because the heads are exceeding 120C then I have much bigger problems to worry about.

I have listed a couple of companies I've used recently to buy seals in the Alt Parts thread.

polymax is a good place to order i got new heat barrier o rings from there to.

Thank you. I'll go for the nitrile.

Cheers Mark
