Change your Macroline

[punkncat]

Just as a reminder to everyone to check and replace old or worn macroline. This stuff is not made for permanent installation, and should be replaced at regular intervals.

This reminder comes as the aftermath of seeing not one, but two different peoples markers blow line off today. One of the two came away bleeding on his forearm from the pressure vent.

I am now going to make replacement a scheduled item, like disassembly and cleaning.....

This stuff is not made for permanent installation, and should be replaced with SS line.

Fixed...

Why would I want a plastic line down stream of 4500psi?

[Sumthinwicked]

since i have used it maybe 12 years no issues on my end
but then again i dont rt my mags

[BiNumber3]

well it's more or less holding 800 psi or so, 1200 at most prolly. Ive never run my mags with pressure that high, but my lines have never burst at 800 psi, tho when i look at the ends they look like they could go, so yea replacement is prolly in order.

I used to do steel hoses, but gettin the right length and quick disconnects everywhere were bothersome:/

[txaggie08]

Almost as bothersome as stitches after macro blew out of the fitting and went whipping around?

I hate macro line, always have.

Ya why bother? Safety last.

[Redic]

yeah i got into a arguement with a local store over this

every marker they have haas macro

and they told me that every marker they work on they replace the SS line with macro
that includes the tippmanns that people still run CO2 through


give me SS line or give me death

Hey, if your reg gives out and you have 4500 psi going through your line, macroline is probably better. I'd rather have macroline blow violently than SS, at least I won't have braid shards in my neck. Or valve pieces.

99% of markers out have some kind of fail safe installed on the gun....Automags blow out the back where you adj your velocity.

I been running 1100psi on my macro lines for about 4 months now and they've been holding up very nicely. I got my stuff to include the fittings from

http://www.airsoldier.com/mm5/merchant.mvc?Screen=SFNT&Store_Code=AOS

Black macroline specs:

* Black Nylon-12
* .150" ID
* .250" OD
* .050" wall
* 1000 psi working pressure (3000 psi burst)
* 0.5" bend radius

I'm not endorsing them but they do have some of the sickest macro you can find/get. Remember, it all comes down to the wall thickness of the line. The thicker the more PSI you can run through it.

I think i purchased this package the last time i got anything from them.

Basically your paying $3 per fitting and getting 10' of the black macroline for free. Can't go wrong with that when most stores sell the fitting for $5 a pop. That whole package would cost you $75 just in fitting and another $10 for the line.

You're dumping 4500PSI to your gun? Damn beemer, get a reg on there.

Do you really think they would SELL somethign that isnt SAFE? SS Line is a PITA, and you know it. Macro line (for the most part) is perfectly acceptable.

The markers arent what you should be worried about, its the tanks.

If your tank has an LP Burst disc, its not goign to be able to put much over the regulated pressure into your gun.

All you yahoos trying to dump 1k+ PSI into your mech's to get them to bounce (then whine about rampers) shouldnt be surprised when a line blows, or some seal dies...

[Newt]

The mag valve is rated to 3000psi (there's a video of a guy actually running it at that, pretty sweet stuff). That includes the valve seals. Macroline is another story, as we all know.

Now I wouldn't be all too interested in putting 1000psi into, say, an Ion.

[punkncat]

Anything that I run high pressure in, like CO2, or when I had mags that I was RT'ing with high pressure....I ALWAYS used SS line for those. There is just no sense playing with your own safety that way.

I use macroline on my LP HPA markers, and anything up to the 850 mark, but I will most assuredly be replacing the stuff on a very regular basis now. I wish I could have gotten usable pictures of dude's forearm. It was pretty damn nasty.

The question is how often should they be replaced? Is it based on time or how often they are used? Maybe I should go with the 3 month/3K mile rule

Agree with the burst disks but if for some reason they fail to fail. I don't want to be around.

Well I'm not worried about a line blowing. What I'm using is rated at 1k work, 3k burst. Would I use it to push 3000psi into a mag...No way in hell but it's more then capable of holding up to what I'm using it for.

Pfft...Seals are a dime a dozen

Like anything under pressure, it's going to swell. All macro line outer demotions are .250 or 1/4 inch. If its over that after a few months of play then you might want to change it. I for one don't ck that, my rule of thumb is when my ends are getting worn from the macro fittings. Main one I usually replace is the one that connect to my valve since it's the one that's usually gets pulled to clean and tune. I keep all my lines a little longer so when they do look bad I just cut about 1/4 in off the tip and reconnect. Saves the line.

[BiNumber3]

the lengths of macro on my gun arent long enough to whip if the ends burst off. unless u mean the middle bursting n shards flying off (the macro i use is pretty flexible/rubbery so i doubt it'd do that).

tho, there is a lot of cheap macroline on the market, that feel very brittle with particularly thin walls.
