One of my first assignments at the place I’m working was to come up with a better way to make a tube take a U turn then paying to have a small metal pipe made.
I found a Y connector the right size and blocked the end of the Y to make it an effective U.
The parts came in today and seemed to work well:



I’m not sure how little room I had for this was clear, so I took the picture again with something to scale it with.


Hopefully this will make the product better.

That is probably at least as handy as most other alternatives, like having to assemble (2) 90 degree elbows with barb fittings and a short length of tube, and more cost/labor effective,too.

I looked at the two elbow idea, but this was smaller.

what about a light stainless steel spring, spiral wound around said pipe to prevent it kinking ? two less points of potential leakage

I'm guessing of course because I have no frame of reference.

The tube has a minimum bend radius that is too big for the space available.
I'm afraid I'm not allowed to give the frame of reference. I'm told we've got one installed up in Brisbane.

thats what spiral binding is for... +shrugs+

At -20C there is only so tight the tube can bend and not crack.

hmmm, I can see why the original was copper ;)

In the -80C machine we can't use pneumatics at all...

I'm sure you'd love it.
-80C robot where you can't use electronics or pneumatics because they both freeze over. Magnetic couplings so all motors are on the outside.
Lots of cool mechanical tricks as it just has to go where you tell it and you can't check on it while it does.
Sadly, I'm not allowed to share.

this is not complicated enough. You need to Rube Goldberg this thing more.

;D

Just teasing, good luck - it is amazingly small scale, thanks for the size comparison.
