microline vs. macroline

[Aslan]

On my mag, the ASA is connected to the gas-thru with macroline. The gas-thru is connected to the valve using microline. Microline used to be the standard in paintball...but now it seems like nobody uses microline anymore. Any thoughts? Is the microline rated differently or is there a possibility it could choke off the pressure to my valve?

I actually think it may increase the pressure as I believe (and I'm recalling 10 year old Physics here) that as the diameter of the piping decreases, the velocity of the material moving through the piping increases. That may be completely wrong...it may apply only to liquid...I really don't know...it's like one of about 4 things I recall from Physics class.

I probably will have to replace the microline with macroline eventually anyways because one of these times when I replace the microline...I won't be able to find any.

If the bore of the pipe were to slowly decrease inside then the pressure may increase in the application. However, since microline immediatly starts as a smaller bore then nothing will happen besides a restriction in air flow.

I would highly suggest switching to a complete Macroline set up, it is a much better as it allows the highest flow of air in the space available compared to microline. Also, Automags require a consistent, high flow air source to operate in higher ROF's.

In short,
Macro>Micro

A larger line going to a smaller line will increase the velocity not the pressure. However, if you maintain a constant velocity, then the pressure will also increase. That is how a jet engine works, by forcing a fixed volume of pressurized air through a smaller opening.

Microline is very durable but the smaller line can restrict air flow, especially in longer line lengths. Macroline is more readily available as well.
