110 is not HP. That's the high end of low pressure.
All tubing carries a psi rating that you need to pay attention to. Most small dia tubing I've seen will not have an issue with 110.

1 liter, 2 liter... HOW ABOUT A 12 LITER ROCKET?! Same config as my last post, how many pumps do you think it will take to pressurise the whole thing to 100 psi?

By the way, the pump is a 1.1" diameter 14" length pump. With an air diffuser (if that is what its called- the second chamber that dissipates the heat produced by compression. Also the gauge is located there)

air compressor will be your friend. or bottled air. I have seen multiple people manually pumping a large rocket, but just one, well you'd need to multiply your number of strokes for a 2 liter by 6 to get an estimate.

Masters here in Aus had a plastic water air line hose 1/4" and 1/8" thats burst rated to 1000psi and working prussure of 250psi.
They are closing down so I bought 60m plus fittings. I haven't tested it yet, will keep you informed when I do.
