You can drive from store to store "building" your tun and waste time and fuel or you can spend about ten minutes on bargain fittings website. I ended up doing both. Bargain Fittings was a lot less hassle. The extra shipping $ easily equals your time and fuel. And it's all SS. YMMV
Crabs and beer were meant for each other!
In the upper Midwest theres a chain called Menard's and they had 6 packs of 5/8" stainless flat washers for $1.50 or so. My only issue is that I can't get the hose barb and ball valve far enough onto the nipple for the 10 gallon tun unless I use like 9 washers, and the whole thing is too narrow for the current 5 gal home depot HLT. ( I'm using a 5 gal. HLT and a 10 gal. M/LT). I'll be using for fly sparging once I can get the right parts for the 5 gal. Any suggestions for either dilemma?
+1 True Value. Less then 20,000 people in the whole county but they stock better beer widget stuff than the big box in the big city. Take a washer that is close to what you need or make a cardboard cutout of what you need. I have even showed them a cell phone picture of my problem and had them find a solution or work around.
Check a local hardware store. Stadium hardware had them here in Ann Arbor. I should have gone there first instead of going to Lowe's or Home Depot. They always have what I need with someone who knows what they are talking about. Their building is not a stadium so you don't have to walk a mile between sections, and they are usually a very quick in and out for whatever you need.
