another leaking mash tun

so i got my coleman cooler. you know, the blue one that 90% of the world has.
it can be seen here


i got my conversion fittings from bargain fittings. the guy on here.
i also got my weldless ball valves and sight glasses from him too for my BK and HLT. i am in no way bashing his products. everything else works great except for this one on my mash tun.

it just seems like the o-rings are too small. like they just fit into the hole instead of seal the hole.

if i were to take one of those silicone pot holders or something like that and make a washer the size of the one that came with the unit. do you think that would seal it up.

here is the link to the fitting i bought.
Bargain Fittings

i got the first one under cooler fittings. the big washer on the left (this would be inside the cooler) is what i plan on duplicating in silicone and putting between the washer and the cooler wall.

Flat gaskets work too. If you can pinch the cooler between 2 washers...make washers out of inner tube...
Trace it with a pen and cut with a scissors...Install with food grade silicone sealer and wipe off excess...

Have you seen my leak free bulkhead thread?

I wish I saw that a couple days ago...good info AZ...!

good call with the food grade silicone. is food grade stuff at hardware stores?

bobby, good thread. i'll definitely use some of your ideas.

I asked the guy at our local hardware store about food grade silicone...They only had one kind...
Clear...Maybe 5oz for $5...Enough to do 20 coolers...

um, no credit here -- it's Bobby_M's thread - I just posted the link!

Is this a drilled out hole or did you use the stock hole?

Thanks and sorry you had problems with the cooler.

Email me if you can't get it to work.

Thanks,
