Why is LEGO Pneumatic Tubing and T-Junctions so expensive?
Pneumatic Tubing and T-Junctions was released in 1989 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
