I'm guessing that either SMC isn't sponsoring FRC as much this year, or the pneumatic fittings were eliminated as a cost-saving measure. Push-to-connect fittings cost anywhere from about $2-$10 each for 1/4" OD tubing and either 1/8" or 1/4" NPT thread. So that entire bag of fittings from previous years cost around $150-$200 dollars.

However, I'm really concerned about rookie teams not knowing these connectors exist and not using pneumatics because they don't know how to connect them. If this continues, existing FRC teams probably have enough of these fittings to last two or three years, but after that most teams will have run out of them. I certainly hope these are included in future years and in rookie team KoP.

In case anyone was wondering where to get more of these, you can buy more push to connect fittings at MSC Direct or McMaster. If you are looking on McMaster, search for "push-to-connect" (without quotes), then select the type of fitting, then select "For Use with Air", then select "For Use with Polyurethane tubing".
