most blocks actually have 2 barbs. go to www.petrastechshop.com
and get all of your stuff there.
er. the other fitting on some of them you are supposed to block with a flow stopper. I think it just gives you more options in configuring the tubing
looks cheap and shoddy to me. how much are you looking to spend? it really all boils down to price limit.
