I'm running two water filters in series connected with a 1" x 1/2" stainless steel NPT nipple I bought from Brooklyn Homebrew HERE. The only issue is that the nipple is a little too short, so it leaks a bit. I was looking around for a longer one (2" maybe?) and came up with THIS, but wanted to make sure this looked good, since I'm terrible with metallurgy and picking out fittings over the internet. Sorry if this seems like a dumb question!
