I'm in the middle of trying to convert a Coleman Xtreme 70qt cooler into a MLT, using the parts and technique this guy used:

Building a Cooler Mash Tun | BrewMoreBeer

I've run into a little problem. When I removed the drain valve it came with, I broke the inner rubber gasket that came with it, and the hole is too big to get a good seal with the #15 o-rings. I went back to Lowe's to try to find some kind of rubber gasket or washer to get a good seal, but couldn't find anything. I searched the web and these forums but couldn't find a good solution. Any ideas?

I just finished converting an 10 gal "Igloo" water cooler into a Mash Tun. It was the same idea as the one in this thread:

But the hole in mine was close to 7/8 so I found a grommet like this at Home Depot:

RPD Products | Grommets

It worked great!

The bargainfittings.com vendor guy has a gasket on this page:
Bargain Fittings

might that work?

He's on HBT, so you could probably PM him for more info on the gasket...

Logan - thanks for the idea. I picked up a grommet like that but it still leaked.

shorty - thanks for the link, I think that may be exactly what I am looking for. I found some rubber washers, the inner hole is too small for the 1/2" nipple but I thought it might work. Just tested it out and it still leaks. Plus it smells strongly of rubber and I am not sure it would be safe for brewing purposes. I went ahead and ordered one of those gaskets off his site, so hopefully that will work.

I found that at Lowe's, Ace and home depot have various neoprene washers that worked well for my cooler bulk head. I think I used a 5/8 washer and trimmed it down to fit, I also used a plastic nut to secure it. This is an old picture of my first bulk head, I put the neoprene washer between the valve and the outer wall of the cooler.

In what department did you find the neoprene washers? I looked all over Lowe's for something like that, and when I asked where I could find washers, the guy showed me the rubber ones with the nuts and bolts. I asked if they had anything else like that and he said no.

I love my Coleman Xtreme 70qt. I'm guessing, between my father and I, we've got at least 20 5-10 gallon batches on it and it has held up well. I noticed some slightly warping on the inside, but it hasn't gotten any worse since I noticed.

I'd love to find out what type of efficiency you get using the braid. I avg 75-85% into the boiler with mine, using a manifold.

It's a pretty big footprint to have just freefloating around. If you're ever considering moving to a copper manifold.. here is what mine looks like...

Hey Janzik -

I'm in the process of converting my 70qt Xtreme Cooler with a copper manifold and I'm starting to get worried about the dead space underneath the outlet. Do you have a lot left over in the cooler after you are done mashing? Am I worrying for nothing?

I found them in the hardware/fastener section, in the bins.I think they were near the nylon washers.

This is my conversion...

As far as a new gasket, something I found was getting a silicone baking dish (found a 8"x8" one at a Tuesday Morning for $5) and cut out your own silicone gaskets... I am using two in my E-HLT... Work great... And you can make them as large or as small as you want...
