Fluid I.V. for filling

[burbguy82]

I had some material to make this contraption, a prototype, gravity fed filler.

The main tank is PVC

The tube is typical silicone tubing, and clear vinyl tubing

The metal parts are copper and brass.

Valve seal is delrin

The cap is some kind of rubber.

Question is: is there any adverse effects of these materials in storage of ATF or gear oil? In other words, I would like to use this to fill troublesome spots such as a t-case or filler tube-less transmissions. Gravity fed. If there is fluid left over from the filling process, will there be any degradation of the fluid by the materials, such as "leaching" or any other technical term that would be bad for the fluid in the contraption.

@MolaKule or other chemical gurus?

That's basically the process I use to use, in particular for gear oil: gravity.
From above the engine bay.

Just keep it clean, if necessary flush the tubing with the oil you want to use
for your next job. I don't see adverse effects worth mentioning when done
with some common sense.

The metal parts and silicone tubing are resistant to petroleum oils. PVC polymer, clear PVC tubing, and Delrin hold upon well too per these compatibility charts:

PVC Compatibility

Delrin Compatibility

The rubber cap is not constantly immersed in any fluid and should hold up fine.

My fluid fill device is not nearly as elegant. It is a simple polyethylene Nalgene bottle with two Tygon tubes connected to the cap. I fill the graduated bottle with fluid (e.g., ATF, MTF, etc.) then insert the longer tube into the gearbox. Then, I apply low pressure shop air to the short tube with a blowgun to force the fluid out of the bottle via the long tube (which extends to the bottom of the bottle). Very easy to regulate fluid flow by moving the blowgun nozzle away from the short tube's opening.

I spray my large syringe out with brake cleaner between fluid types.

Nice contraption, but overly complex for my liking. I use a funnel and push a long piece of clear tubing on it. I fill differentials and t-cases that way.

Just my $0.02

That is a nice rig. I experimented with something like that, but I do not have an air dryer on my compressor. I like the simple setup you have. Thanks for the info.

Right, done that. This can be filled and hung, and the valve at the bottom allow a clean stop rather than a king in the tube. I had the stuff laying around. Sometimes the funnel thing can get messy, in my experience

That's pretty cool.

I don't see any problems.

Well fellas, thanks. I did do some research on the subject before hand, but there is always inside info.
