High Temp O-Rings For Weldess Ball Valve / Thermometer - McMaster?

I can't seem to find anything similar to the red, high temp o-rings that come with the weldless thermobob kits from Midwest or Northern Brewer. I was thinking maybe McMaster has some but haven't looked into it yet. I know they have the o-rings for corny kegs... so assume they'd have the fatter, red high temp rings for use on weldless applications. Has anyone ever looked into that? I found a ton of o-rings at the hardware store, but they're just not beafy enough to work on a weldless install. I've tried, they work on cooler conversions, but not on aluminum or stainless steel vessels. Ideally, I want the same ones offered in the kits I can buy online but without paying 12 bucks a piece for the kits.. plus shipping. I was also curious if anyone has found the larger washers and large stainless nuts anywhere other than a home brew supply catalog. Again, I assume I can track that stuff down on McMaster or Bargain Fittings but before I tuck in to start researching, I figured I'd ask first.

So... best place to cheaply purchase hi-temp o-rings, washers, and nuts for weldess installs on keggles. Any direction, advice, suggestions? Hack Depot and Lowes don't seem to have anything I can use other than the brass valves and misc. other brass fittings.

 

Depending on what size you are looking for. Here is what Kal from theelectricbrewery.com recommends for his system.

 

Search on amazon or eBay for " silicon o-ring". There are plenty.

 

Harbor freight sells viton o ring kits. I use a few of them in my mash tun. But they should be fine in a boil kettle

heckels... do you have a part number for the ones I can order from www.oringwarehouse.com?

 

I don't. The one I ordered was a 12.5" ring for my conical. If you reference the o-ring chart stickied at the top of this forum it'll tell you which size you need. Then select from the o-ring website's drop down.

Not sure if they'll have a minimum quantity in your case. My one large o- ring was all I ordered.
