Possible cheap air distributor?

So, would this work as a manifold:

downsides: no check valve.

BUT... i want to use it to connect up to 4 kegs to a spunding valve for fermenting under pressure. any reason this won't work, or i should go for a more traditional manifold?

Aquarium pumps do not have hardly any pressure to them i doubt if they push 1 PSI. This thing would explode if you put beer carbonating pressures

you usually get what you pay for - $3.99 for four valves? I don't know about "exploding" but they won't hold up - they'll leak and drain your CO2 tank in minutes.
