Micro/Macro Line

[awg9tech]

Does anyone know the burst/working psi of the micro/macro line(s) that is being used on markers now? Is there a burst/working psi ratio that the marker industry has established?

[awg9tech]

OK, I didn't do a post search before I posted the initial. I see that this has been around before. My concern is that I have yet to find a micro line fitting with a working psi of more than 260psig. The psi out of my reg. is ~800psi. I don't know of many people that run the reg. much lower than that, much less 260psig. If anyone has a link for micro fittings/line that states a sutable working psi pls. post it. And......what is sutable working psi? I've heard 4x working, is this true?

Forget the Micro. It can be very unsafe. Use Parker Macro or stainless only. Parker Macro is rated to 500 psi working pressure so its good for 2000 psi. Everyone knows where to get it.

[awg9tech]

Precisely my point. A working psi of 500, so, use it anyway?? Like I mentioned, my req. output is ~800psi, 300psi over the working psi of the aforementioned macro line. Am I missing something? I am asumeing that the "working" psi is what the industry has deemed safe. Am I wrong?

[Tunaman]

Yes...use it anyway. It will not burst untill you reach upwards of 2000 psi.

OK, I also have a fiber wraped 3000psi tank. Burst psi is 5k. So it's OK to fill to 4500? I'll be sure to tell my local field that.

[Tunaman]

Well in that case, you should go get some 1/2" thick, 3" diameter, case-hardened pipe and use that on your marker. You should feel safe then...

I don't mean to sound sarcastic. I know what you mean about industry standards. The problem is that The parker macro is the best there is (that is strong enough and flexible enough) for paintball use. The difference in the Tank specs and the Macro specs is that it is ILLEGAL for anyone except certified DOT inspection stations to fill your tank beyond the rated pressure. The 4500 psi tanks can hold 10000+ psi. There is nothing 100% safe about this sport.

The usual thing is 3x rating is burst, some manufacturers rate at 4x, which I applaud, but I still don't recceomend using anything other than SS Braid unless you are running a LP setup, with a LP Air System (Output of Air System is sub-400psi), otherwise you are pushing it. Yes the colours of Macro are neat, but safety is Job 1. SS Braid is usually rated at 1500+ psi, I've heard of it taking full pressure from a 3k tank with a blown reg.

I don't really see any "catostrophic injury" happening with macro line. A couple stitches in someones finger, perhaps, which as far as I am concerned is still a minor injury. I've bled enough to get dizzy on a couple occasions, and I still wouldn't count those are serious injuries, though.

As for safety, Macroline may have a WP of 500 PSI, but look at the track record, esp. at parker in particular. It has been used by people for YEARS without bursting. Its solid stuff.

It all comes down to what you want to do though. If you don't like putting 800 PSI in 500 PSI macroline, then don't use it and quit complaining

mykroft,

I'm using something similar to SS braid on my mag, but the exterior is black. It has a 3000 psi rating written on the exterior, if memory serves (not at home right now or I'd check to be sure). I believe it's fiber wrapped rather than SS braid, and is generally used in hydraulic applications. Got it from the local paintball store as a substitute for SS braid. Looks nice too, though SS braid would have looked pretty good as well.

Well any nitro tank HAS to be able to do 4-5 times it's regular fill pressure, that's the rules.
