Topic: Air pressure and water tight possible?
Is it possible to make, a clear cylinder about 1inch tall by 1/4" diameter out of ABS that will withstand up to 80psi and 40psi?

Is the 1/4" ID or OD?
ID
Or bigger ID. Just in general?
It should be possible, theres only one wsy to find out! your problems are going be at your end caps, which would be pushing the layers apart. Puting large internal radius in will help. The hoop strength should be pretty decemt especially if you make it nice and thick. Make sure to have your starting points on random, so you don't have a weak seam.
Be sure to gradualy raise pressure as you test to be safe. Plastic shrapnel is no joke. The link below will have more than enough info to get you going, also a great resource in general.
FDM is generally not watertight, so definitely not airtight. If you post process with a solvent you might get airtight, but 80PSI is asking a lot.

Just so you know, the public water supply is not under all that much pressure. 40 to 50 PSI in most places and can be as high as 100 PSI in some. That being said I made a shower head once that had individual arms with holes in the end to create a vortex like affect. It was on thingiverse, not my design. Anyway I printed it with 7 perimeters just to be safe. Even with that it still leaked more water over it's body surface than it actually sprayed. Looked like it broke out in a cold sweat.
I was to busy thinking about strength than actuslly sealing. Duh! Ive only ever water seal tested some vase cup type prints,no leaks there. An interesting task for an fdm printer. I wonder how a larger nozzle from the volcano would do?
I found this from stratasys. Even with a sealant they say 65 psi
