I had to fix a water leak today at a really crappy looking warehouse. I was kinda shocked when I went inside. Just wanted to share.
This first one was used in the 3rd movie.
Silicone or vinyl tubing goes on the barbed end. Most reactors come with barbed fittings also. The brs ones have john guest fittings but those can be removed for barbed ones.
I ran it for well over a year and I gave it to @jstiltne over a year ago and he just sold it to someone else here in the club. It's still going around 3 years later.
