Fda silicone o rings retailer

[samandbekah]

Does anyone have a good resource for purchasing o rings that are fda food grade material?

I'm looking for a 4mm (thickness) by 20 mm (inner diameter)

Thanks!

I don't know that they specify FDA, but I've ordered from http://www.oringsandmore.com/

Fantastic and thank you, I'll check them out. They have the size I need just need to find out if it's food grade...

Yeah I tried them but they wanted a minimum $250 dollar order since they'd have to manufacture them

How did you come up with those dimensions? Did you custom cut a part that was designed for that specific size?
O-rings are very standard and are called out as dash numbers... it looks like this: -001 for thinnest, -101 for thicker, -201 even more thicker, and so on.
The dimensions you've given are roughly -211 (20.22mm x 3.53mm) or -315 (19.99mm x 5.35mm).

I ordered a ss brew tech bulkhead from more beer.com and it required a 7/8" hole. I am not a welder so I opted for weldless fittings and I found a punch that was 15/16" which morebeer informed me would suffice.

Long story short I noticed a very small leak, almost negligible, but I could not settle for that. I contacted ss brew tech directly and they suggested 20mm x 4 mm should seal it up. They provide an o ring that is 20mm x 3 mm so it's just a tad too thin to seal

Thanks to the poster who suggested o rings and more, they had the size and food grade silicone. Testing it out as soon as it gets delivered!
