I think this part was used in Legos early pneumatic history. You ran a hose from your pump to the center port on the 2 X 4 brick. You then ran a hose from each side port to the top and bottom ports on you pneumatic switch. Another hose ran from the (...) (26 years ago, 22-Oct-98, to lugnet.build)

Much agreement from me!
