Re: kit of parts tubing

[Public service announcement] regardless of the tubing rating that doesn't mean you should have anything 175psi on your robot. High side of the system 120psi max. Low side 60psi max. The tubing you got in the kit is fine for this application.[/PSA]

Re: kit of parts tubing

If it was in the KOP, you can be 99.99999% sure its legal to use.... at least, for its intended purpose anyway.

Re: kit of parts tubing

I dont think its at all possible to have a KOP item thats illegal .
As far as pneumatic tubing goes my teams colors are red, white and black . Instead of using this years ORANGE TUBING , i nabbed some of our old BLACK kop tubing

I believe that the criteria for tubing would be this, not going over 120 psi in general. If your psi is going to be 175, then you have something else you need to fix, not the tubing. Do you have safety switches installed?

On second thought, if this is scrap tubing needed for a project outside of competition, then I really have no idea.

It sounds like either you or somebody on the GDC is a little confused about what pressure the tubing in the kit is rated for.

No... Wait.

We are saying that the tubing that come in this years KOP is illegal due to the this post on the Q&A.

Quote:
No. Any additional tubing used on the Robot must satisfy Rule <R87> and be functionally identical to the tubing provided in the Kit Of Parts. 175 psi tubing would not satisfy this criteria. Furthermore, heat treating the tubing will alter the physical characteristics of the tubing, and again make it dissimilar from the tubing provided in the Kit. Coiled tubing rated for 125psi that is functionally identical to the tubing provided in the Kit Of Parts is available from several commercial sources.
The tubing that came in the this year KOP is rated at 175psi, we are not saying that we are running at that.

So the question is can we use it?

edit: Sorry slow typer.

We posted that with this year KOP tubing in hand and read the rating off of it.

Then it's the GDC that is confused. While the answer about coiling your own tubing should still stand, the rest of that Q&A needs to be revised. I would recommend submitting a follow-up question so they can clarify.

Re: kit of parts tubing

I posted a clarification question on the Q&A yesterday when I saw that Q&A post. So check back on the pneumatics Q&A forum soon and a clarification should be there.

I just looked at the Q&A post again, and they corrected it. They removed the sentance that said that the "175 psi tubing does not meet the criteria." But my post should still be clarified soon...I hope.

Re: kit of parts tubing

if you read freelin-wades's rating of 175, i bet you can pump that up to around 250ish... just for safety they have to crank it down.
