Macroline PSI

[Jim888]

quick question how much PSI is a macroline suppose to be able to hold? I have one on my X-valved ULE mag and have an armagedon airamerica tank on it psi around 1000 worked great all day I let my brother use it and he put it in the back of my van and when I went to get it out tonight...no air in the tank...(he forgot to turn the on/off in to the off position)

and a big hole in the line...

thanks for any help

thats happend to me before on my mag, I could try much more then 800psi

I think stainless is rated to something rediculus like 5000psi

[Chronobreak]

think most is rated at like 500-800, but can take 1200 + for short periods

the odler the line and more pressure, the more liekly it will break

Never leave paintball guns and tanks in the car. The temp inside could almost double and cause the tank to overpressurize and blow, causing serious bodily harm.

Most macroline has a burst around 800-900 psi but it does vary from manufacturer to manufacturer. The hose is "rated" to only 300-ish psi but it can take more before problems occur.

You can get stronger hose but it's oftentimes much more stiff. The macroline I sell has a burst aroun 1200-psi, but the bend radius is much wider.

Some of the macroline fittings themselves are only rated to 290-psi...lol

I was pretty sure the parker macroline Tuna uses is has an extremely high Rating, somewhere in the 1-2000 range.

think its 1200, cause mine def blew at around 1500, along with the elbow 90* fitting and guage(1500 psi stock guage)

The Parker macro line is rated at 625psi operating pressure but has a 4x burst rating (2500psi), which is higher than most other products on the market. It is a bit stiffer though.

The ratings are at ideal conditions. Any blemishes or scratches on the line derates it.

So if macroline is only rated for 600 psi, why do we regulaily put ~900 psi down it?

I got a tank filled by a friend a couple weeks ago. It's a smartparts tank, so it has an on/off. According to my friend the guy filling the tank "adjusted" the reg for me. When I turned the valve open I saw the output gauge needle dip WAY past the 1500psi mark and the hose blew instantly, from about sixteen inches from my head. This was three weeks ago and my right ear is STILL ringing. That's why I went and bought about five stainless lines right away.

If people are selling stuff rated even above 1000 psi you should be really careful if you have an adjustable tank.

Macro line that I sell is rated at 3k. IDK why in the (bleep) you all would even consider anything less. The standard fitting that co2 and compressed air (nitro tanks) are rated for 1.8k (thus the burst disk pressure) so anything less than that really would be asking to get hurt.

EDIT: For co2 users...
1.8k is what the valves minimum rated value is. Companies like Pure Energy and Catalina (just the ones I know of off hand) make their valves at a higher quality and thus rate them for 3k. So there is absolutely every chance that 3k of pressure could (note I said could) go into your lines if

Never leave paintball guns and tanks in the car. The temp inside could almost double and cause the tank to overpressurize and blow, causing serious bodily harm.

problem is, most macro fittings are rated way less than the line is.

[Teamslayer76]

The majority of macro line is rated at 850psi, while others are lower around 600psi. I woudn't try anything over 800 at all on macroline. Stainless Braided Hose on the other hand is nearly 6,000 psi burst pressure. :)

quick question how much PSI is a macroline suppose to be able to hold?

Very easy to answer. [b]IF[\b] you can tell us who the manufacturer of the line is and which product line.
Let the disinformation and scaremongering begin!

think most is rated at like 500-800, but can take 1200 + for short periods

[b]working pressure[\b] and [b]burst pressure[\b]. WP is the pressure you are not supposed to surpass. If you surpass it, chances are the line may be no good. It certainly no longer has the same BP rating.

the odler the line and more pressure, the more liekly it will break

That at least is true. Line should be inspected and replaced regularly.

Never leave paintball guns and tanks in the car. The temp inside could almost double and cause the tank to overpressurize and blow, causing serious bodily harm.

but it does vary from manufacturer to manufacturer.

The only true thing you said. It also varies from product line to product line.

The hose is "rated" to only 300-ish psi but it can take more before problems occur.

The Parker macro line is rated at 625psi operating pressure but has a 4x burst rating (2500psi), which is higher than most other products on the market. It is a bit stiffer though.

So if macroline is only rated for 600 psi, why do we regulaily put ~900 psi down it?

Because the vast majority of paintballers are blisfully ignorant and the industry has been lucky so far...

1.8k is what the valves minimum rated value is. Companies like Pure Energy and Catalina (just the ones I know of off hand) make their valves at a higher quality and thus rate them for 3k. So there is absolutely every chance that 3k of pressure could go into your lines if something happened to the reg. Not to mention liquid co2 could get into lines as well.

While I agree with what else you posted, 3k will not get into your lines. The burst disk should blow before that.

problem is, most macro fittings are rated way less than the line is.

No. Correctly matched line and fittings have matched ratings.

The majority of macro line is rated at 850psi, while others are lower around 600psi. I woudn't try anything over 800 at all on macroline. Stainless Braided Hose on the other hand is nearly 6,000 psi burst pressure. :)

I just checked with Parker and they do have an 800psi working pressure macro line with a 3200 psi burst which is higher than the 625psi line. It still isn't high enough for the working pressures of paintball applications, but better than most of the alternatives which are lower rated to start and only have a 3x burst rating.

The Parker line rated at 15000psi is not the same item as macro line. It won't fit the connectors and is made differently.
