sorry i cannot type Chinese.

i want to add an airtank to my airbrush setup. i searched and found out that Pepsi plastic bottle can easily hold 100psi. i wonder if anyone has tried converting a pepsi bottle into an airtank.

100psi is not a lot, my bicycle tire can hold that much.

my airbrush compressor only goes up to 40psi before cutoff, which is way below the limit of the coke bottle.

VampireA got it right. the issue is the connector. if drill a hole on the bottle cap properly, it should be strong enough.

how much is the power air tank?
