I'll show you a fairly simple way to put one together out of easy to use plumbing parts.
Step 1: Assemble parts and yer tools!
- A medium sized cooler, say 30 quart or so, it doesn't need to be huge.
- At least 20' of copper tubing. I used 1/4" ID. I would not go any larger than that. The outlet tubes in the Pepsi type kegs that this is for are about 1/4" ID, and you don't really want to be larger than that if you can help it. Being larger in diameter would give the beer time to expand on its way to your glass, resulting in a glass of foam. Boo.
- Tap w/ 4" shank. The length of the shank doesn't really matter so much, so long as it fits through the wall of the cooler.
- A short length of think-walled vinyl tubing to go from the fitting on the back of the tap to the copper tubing.
- Fittings to adapt the vinyl tubing to the copper tubing. For the copper tube fittings, I chose compression type fittings for their ease of use.
- Pipe seal (Teflon) tape.
- Not pictured: wrenches of various sizes for tightening the fittings together.
- Adapter from garden hose to nipple, same size as all the others.
- Cheap vinyl tube to fit the nipples from garden hose to inlet, for leak-testing and cleaning. The stuff I got is rated to 45psi.
- Step drill bits, or standard drill bits, in the sizes you'll need to put the holes in the cooler.
- One cat, preferably white.
- Zip ties. Lots and lots of zip ties!
I've been purposely vague on the sizes of the fittings, and the sizes of wrenches and tools for the simple reason that you may not be able to get the exact same sizes of adapters that I did.
All of the fittings were purchased at Homebrew Heaven, in Everett WA. The copper pipe was picked up at my local Lowe's, which I paid too much for, but I wanted to get all the parts all on one trip.
