If the Igloo coolers have a hole and spigot gasket that is larger than the Rubbermaid, then by all means just upsize to 1/2" parts instead. The general design should still be the same.

My whole purpose in using the 3/8" parts was that they fit the Rubbermaid spigot gasket PERFECTLY. If your parts fit a 1/2" gasket, then that will work too (in fact, some might prefer the larger hardware, albeit slightly more expensive).

I actually put together Fly Guy's exact design yesterday and had all 3/8 parts but could've used 1/2 instead. What I did though was to use 1/16" thick rubber washers that had a 5/8 ID to fit right over the middle of the double male threaded piece. Put a rubber washer on either side and tightened it down on both sides. Filled it to the brim and let it sit for an hour and no leak to be found.

Brewed 30 minutes after that still great.

Thanks Fly Guy for all the info.

I got her to work lol. It cost me an extra $3 to return everything (all parts X 2 - MLT & HLT) and exchange the 3/8 for 1/2. Works like a charm. Used the same exact design only everything 1/2 rather than 3/8.

Can't wait to brew with em.

Does the configuration that Flyguy talks about here, also work at the top of the MLT if you intend on recirculating the wort with a pump? I'm concerned with the contour of the round cooler. Maybe a flat walled cooler would be easier to attached the higher inlet connection. Any thoughts?

I had a hell of time getting mine to not leak out around the ball valve. I reused the original washer that came with the original spigot, SS washer and a couple outside. Tightened it so much the cooler was screeching. I ended up going to Lowe's and getting a 5/8" rubber grommet. I put this in the hole for the spigot, then did everything as instructed minus the factory rubber washer. NO LEAKS I am proud to say...

Actually, over-tightening is the leading cause of leaks. Did you try backing off a bit? I bet that was it.

Also, did you use teflon tape on the fittings? That's a must (for the nipple and ball valve at least).
