10 Pack of Colour Coded Silicone Post O-Rings (5 x Red Gas + 5 x Yellow Liquid)

We've all been there, not looking or not thinking and trying to put a gas disconnect on a liquid post.
Yes, there's a knotch in it, yes there's words IN and OUT. But you're busy! You don't have time to go searching, it should just be BAM! in your face obvious that it's a liquid or a gas post.
KegLand finally has the answer made possible by our KegLand Home-brew Community Group on Facebook, the long awaited colour coded Gas and Liquid Post Sets Red & Yellow.
