Safety Issue with Macroline

[nak81783]

I've read that macroline is usually rated for a 500 psi operating pressure. How can this be safe with any CO2 tank, or with nitrogen systems with an output pressure of more than 500 psi (almost all guns need more input pressure than 500 psi, except those optimized for low pressure operation)? I know some people out there will probably say, "Oh, I've used macroline with CO2 in 90 degree weather and an overfilled tank and never had problems with it." But seriously people, how safe can it be with a 500 psi rating on it? I've also read that macroline can come with higher operation pressure ratings. What brands are these and where can I get them? Thanks.

i'm almost positive that macro lines handle more than that. i've never had a problem with them in the past. if they couldn't handle that pressure, why would everyone use them? that's just the way i figure it.

500 psi is the average safe working pressure. The full rated line pressure is 4 times that or 2000 psi.

I feel like I've betrayed AGD for seeking paintball information from other than this site, but here is the link where I read about macroline. Notice, that they failed to mention that it can handle a higher pressure than the standard safe operating pressure. Thanks a lot for your help guys.

i've run my mag at 800-850psi for a year with the same line. no problems at all. they are not rated at 500psi

CO2 will weaken macroline. But it will tank a long time for the macroline to weaken enough for it to blow, so it's all good. Microline is a different story though.

mIcro is usually a 2-400psi working, and mAcro is usually 4-700 working. depends on which company you get to make the macroline. some will make high and some will make less. the WP SHOULD be printed on the side of the macroline

Well, I have guns that are running SS Line, Macroline, and Microline. And I like the Macroline(that's the smallest)the best. It is flexible, strong, and easy to use. The SS is nice but isn't flexible. And I really like how easy it is to use the Macro and Microline. Because you can disconnect the line really easily. Mine never leaks and has never had any problems.

You have it backwards again...Microline is the smallest and is no longer recommended for paintball applications.

that we are on the topic, I remember hearing that teflon tape has a standard safe working pressure of 60psi, is this right? Ever since I heard that I have been trying to use Loctite 545 for most of my air fittings. However it's not like I took off the old ones and loctited them back on.

explosions

not to be an alarmist, but I've had macro line explode on me. It was a hot sunny day and I was using CO2, which didn't help any. I also had occasional leak problems, so I've switched to SS hose. No more explosions.

Macro is usually rated for 500psi, which means 1500psi burst pressure. Shocker Macroline is 250psi(750 burst), I've seen that blow, though it was on a Bushy, running about 600 into it. SS Braid is 3000psi rated, for 9000psi burst pressure.

Think about it, SS Braid should be able to take the hit from a reg failure on a 4.5K system, anything else could have problems taking full pressure from a CO2 tank in warm weather. I do run Macro on my RT, but SS braid is definitely in its future.

Just get quality lines, don't let it get too old, and replace it at the first sign of wear and you should be fine.

I had macroline explode on me the first day out. It was about 85 degrees and I run co2(no option where I live) so I have changed back to ss braided lines.

SS is always just better.
I think its parker or something similar who makes the good macroline.
