I need a part number for the o ring at the end of the hydraulic hose of the master cylinder. This is for a t56 equipped fbody.

Looked on Ticks website and did not see one. After a little reading I found it needs to be made of a material that works with brake fluid so not all orings will work.

 

so you mean the one at the quick disconnect ?

It's just a regular EPDM o-ring you need. NOT Viton. The Viton will expand ( that said....I did buy viton at first before I found out it wasnt suitable, and I'm near sure it's been on my car since. But I do expect if I need to remove the disconnect...it'll be messy lol.

I bought some a few years ago....I think they were 2.0mm thick, and 12mm ID

 

Thanks, I looked up some places that specifically sell orings and plan on buying a few different sizes. I measured the old one best I could. Gonna check the measurements you posted and see how close they are with mine. They have a 1 dollar minimum order from the place I’m looking at so I’ll have to buy several anyway.
