Modifying Pneumatic Tanks


I wondering if there are any safety issues with modifying pneumatic tanks. What we were wanting to do was cut the threaded ends off of the cylinders so that they had shorter length overall. Thanks in advance.


Hi Issac,
These storage vessels are pressure rated for the configuration they are sold in. As such, any modified storage tank would no longer be guaranteed to function.

While it probably won’t cause any issues, we can’t be sure. To be safe, we recommend ALL users keep the pneumatic components in their sold configuration.

Thank you for your reply.

I have a question that I forgot to include with my original post. Would it be VRC legal for us to modify storage tanks?

Hi Issac,
It sounds like you’re looking for an official ruling from the VEX Robotics Competition GDC. These rulings can only come in the Official VRC Toss Up Q&A forum:

I will copy your post into this forum so you can get an official response.
Let us know if there is anything else we can do for you.
