Pneumatics kit out of stock

When will the pneumatics kit 1 be back in stock? Additionally, is there anyway to see the average shipping time for vex products before ordering them?


This is something to ask the sales team at vex, go to the bottom of the order page and look for the sales representative for your region

No need to buy from vex, just go to SMC and buy from there SMC part numbers?.


You will likely get “ships in 8 weeks” or “backordered” if you want it from Vex, especially since this has been an ongoing issue since last year!

Our team created this spreadsheet that works in conjunction with the Pneumatic 1A-add on kit when it was still available and its alternatives from SMC, McMaster. Further third-party parts can be found in this spreadsheet which I think will be more useful because all of VEX pneumatics are out of stock.

We ordered our pneumatics from VEX back in September. Certain parts shipped in November but we didn’t have everything until January.

I bought everything from SMC, and it all came in except for the single acting pistons themselves, they are back ordered by 160 something right now I believe. The date they would be back in stock was January 25, but I haven’t heard anything about that.

We are currently borrowing a single piston from another team with a spare in our area.

I’m surprised that after making an order from SMC, you are still calling your air cylinders “pistons” since it is impossible to buy a “piston” from SMC, you would have had to order a “pneumatic cylinder”

But these air cylinders are in stock at as of the date of this post, it looks like they have 47 in stock in the US. Here’s the link to double acting air cylinders (I generally don’t buy single acting cylinders for our organization)


I am very sorry, @kmmohn, but you are fighting a losing battle here.

While you are absolutely correct that every collegial level engineering textbook calls this pushy thing a “pneumatic cylinder”, every third-grader will tell you that pushy things are called pistons.

Then every fifth six-grader will recite to you the recipe for for making one and, if you are not quick enough to pretend that you are very busy, will gladly spend the next half-hour explaining to you the benefits of slime blocks and the tips for laying redstone for your automated chicken farm, that you absolutely must build, if you haven’t done so, yet.


I was only able to get single acting solenoids, and SMC + Orange Coast Pneumatics both showed they had them in stock. I will check this out though, thanks for the advice.

Sorry about saying pistons, that is what my organization calls them so I have fallen into a bad habit.

So you can actually run a double acting cylinder on a single acting solenoid, by connecting only one end of the cylinder and providing your own spring return with either gravity or rubber band. Using a double acting cylinder in this way gives extra versatility because you choose which direction is the spring return, or if gravity works for you, no spring at all is required.

I wish we had never purchased a single action cylinder. The double acting is more compact and can be made single action with a rubber band.

This is good to know, I might do this in the future. I do not need a certain one or the other, I just need a piston, and would like a second one for an angle changer.

Thanks for all the information!
