Locating a Part

[crollison]

Can anyone point me to where to find plugs to top off pneumatic lines? For example the other side of a pneumatic solenoid that needs blocked off. Had some given to us but can't find any more and don't' want to go back to what we used to do. Thread a screw into the tubing and bend it over and zip tie.

Thanks.

You can always use a T fitting and connect the two outputs to each other to make a quick plug if you're short on parts or in the rush of competition.

Its not the best but it works and my team used a few on our competition bot last year. You take a piece of hose about 4-5 inches and fold over about 2 inches of it. Zip tie it down with a couple small size zip ties and you have a cap. We usually use these if you are prototyping or need a cap right this second and don't have time to make a hose fitting with a brass cap on it.

Another way that a sophomore on my team came up with is you put a rivet in the end of a hose and it will seal it. Please don't ever put a rivet in a piece of hose and call it a cap because you are just asking to make a bullet by doing so. (on a side note it held up to 150 psi from our shop compressor and we didn't have anything with a higher pressure to test it with)

Just letting you know that the T or cap methods are the only legal way of doing this. A screw, a rivet, or any of the ziptie approaches would not be considered competition legal.

For your use case, it might be better to simply use a 3/2 valve, if you have one, rather than a 5/2. That would give you just a single output that's either on or off.
