Food Grade O ring

[bandit77]

I just stop by are local hydraulic shop for high temp silicone o ring (orange)for my mash tun. The kid behind the counter told me that they had none and sold me...what I believe they are Viton o ring (brown in color). He told me they were food grade, good for High temp and are made of fluorocarbon. At a buck a ring I hope they will do.

My consern...is it food grade and high temp safe?
What do you think?

They are good for high heat I know that. Food grade is another question. I wouldn't worry to much about that though unless it reaks of plastic or rubber.

No smell to them.

If you have the actual part number then type it into Google in the search window. Maybe it will lead you to the spec's. I have done this may times with great results.

I did google search I got some info but didn`t say it was food grade. Did the same search on the silicone one and also didn`t say anything about food grade. So I guess i`m going to try them.

Thanks for the help

Mcmaster says viton is good to about 400F.

This site: (third google result for 'viton food safe')
Materials: Viton, Nitrile, Silicone, Polyurethane, EPDM, Fluorosilicone, Teflon, PTFE filled, PEEK, Nylon, Acetal
does NOT say viton is food safe, but more importantly it says it is NOT recommended for use with hot water or steam.

Doesn't look so good for brewing.

OK
I`ll go back tomorrow and more info on them

Thanks

Even though the site says they have a "poor resistance to hot water and steam", unless they look and feel like a sponge, I bet they would work cranked in between a kettle and spigot.
