Need help with macro lines

[paint_sprayer10]

I just installed a macro line on my gun. im using compressed air (hp) and when i screw the tank in , littlevent thingys pop out and it leaks. PLEASE HELP!

[Corrupted355]

What's the application? It'd help us to diagnose it if we had more info.

Littleventthingeys wear? On the fittings? Make sure that when you cut the line to size that the end is cut perfectly flat. And make sure that you press the line all of the way into the fitting before you air up your marker. It would probably be a good idea to check and make sure that you are using macro line that is rated for high pressure use also (hp lines have a pressure rating around 1,000 psi)...

if i have understood you right you prolly cut your macroline is just a little too short. get a new peice just a little longer. all you might need is it to be about a 1/4" longer.

^^ I agree, you need to make sure its the right length, or it will not lock in, and will just blow out the fitting.

[paint_sprayer10]

the things you push in, on the valves are poping out and leaking. its plenty long.

Either your macroline cut isn't clean and straight or the fittings are junk.

Replace with steel braided. I never use micro or macro lines they always seem to fail at the most critical times.

Macroline can be very reliable when installed right.

For the cut use something like kitchen scissors, if you used a knife then thats bad because it makes a ridged cut. When you make a cut, don't forget to leave it a bit longer because it needs to go in the fittings a tad far (plus you might screw up once or twice).

This should be in the air systems forum BTW.

"Can be very reliable" versus "always reliable".... I have yet to see steel braid fail once, ever; nor do I know of anyone who knows of anyone who has had a steel braid failure. It is possible I suppose but so rare as to be statistically non existant. That speaks for itself, despite reluctance to listen.

Macro (and micro) can and do fail often. The line ruptures, the fittings leak, This has to do with plastic and how it handles continous pressure changes regardless of the pressure rating. Every pressure change fatigues the line. Minutely moving toward the inevitable. Macro fittings have been known to leak from a slight bump, requiring an immediate line change.

If you want to have to replace your lines regularly.. by all means.. use macro. I'm sure the manufacturers appreciate your unending purchases.

So far my macroline has been 100% reliable. Sure it isn't steel braid, but it's a lot easier to work on.

[GrimAssasin]

ive had the fitting on the end of my steel braid crack and blow the line out before...and the tube inside steel braid can break too.

[Corrupted355]

I have to agree with the reaper on this one. If it's at all feasible, go with steel braided. I've seen steel braided fail, but only under extreme conditions. I'm talking a hydraulic check valve fails allowing 10,000+ psi of hydraulic fluid into a static line. You'll never encounter anything even close to that in paintball.

However, anything can fail if you don't maintain it well. Regular checks will do wonders to increase the durability/longevity of any mechanical object. Even Tippmanns and Chevrolets need their oil changed once in a while. That goes double if you go with Macroline.

It fails for people that can't install it correctly. If it fails on you, its your fualt. It has never failed on me (because I can use macroline well). Its really only microline that is sensitive to pressure change, but microline is basicly a whole different thing.
I've never needed to change a line because of failure. I never will, and even if I do I can just pop the line out of the fittings and get like 2 feet for $1.;)

I've seen people screw up with steel braid too BTW.

[sanky]

yea im pretty shure the manufatures don give a poop about the $1 purchases we unendligly make

[paint_sprayer10]

Ok i smoothed them out and tefloned the crap outta the fittings, and it worked, then the naxt day i screw in a tank and my CRX valve blows apart, so whos knows what was wrong. (i think thats what the valves called)

[GrimAssasin]

then im guessing you messed that up somehow. post pics so we know what to tell you about this

[paint_sprayer10]

Its no biggie, im taking it to my local tippmann certified guy on thurday and im just going to tell him "have it firing by saturday', but thanks for the help guys.
