Macro and cable?

[Beemer]

I dont have to ask him. I have pressure gagues on all of my fill stations. The pressure is usually @600psi at room temp. ~75ish

I have filled my own CO2 tanks since I was 12 (Im 23 now). To date I have never had problems with blowouts with micro/macro/any other type of line. IIRC I have only had 2 burst disks ever blow. Both of those tanks were left next to a fire, and probally got a little too hot. Although it is probally not recomended I dont use a scale to fill either. you can usually watch the liquid fill to the top if filled correctly. Think about it most of our remote coils are also made out of micro/macro hose, and I have seen them ran with adjustable HPA tanks.

Im not saying that it is 100%safe to use micro/macro hose, but if you buy from the correct hose you willl not have any problems.

Either way. My .02 is use a line from a decent dealer, and you wont have any problems. Someone who leaves their tank in their car on 100+days probally deserves having their micro/macro burst on them.

First it was 500psi now its 600????

Well either your thermometer is off and its really 40F or your gauges are off by about 250psi.

At 70F CO2 obtains a gas pressure of 852 psi when confined in a vessel.

If your bulk pressure is at 600, A. your tank isnt getting all the way full and B. they're screwing you over on filling your bulks. CO2 in bulk is usually over 1000psi to start out with.


That being said, I only weigh tanks when I think the tank is about to go floater on me. if you fill them inverted without purging it, filling it,then re-purging it(just purge it don't refill it), they will fill to within 1 ounce of being full(I've never seen a tank actually overfill....)

i took the hardline off of my phantom and swaped it out for a macro line, for ease of dissasembly. i was runnin one of them 3.5 oz tanks and i set it on the staging area table, walked away into the proshop came back out to find a gaping hole in the macro line. and an emply tank of air.

Im not sure how this happend but ive seen first hand the hole in a macroline.

Both of my tanks are within 50psi of each other. They should both be full unless they are leaking (I doubt they are leaking if they have held this much air since april when I had them filled last). Im not sure if gague works or not. It has given the same reading for about the past 10 years that I have used it.

BTW the chart shown is for ideal CO2 ie 100% CO2. I doubt any of us are using that.

weigh the tanik the next time you fill it mann.


I'm betting you gto an under filled bulk tank...or maybe our supplier uses a different fill syste, and keep ours at a higher PSI.

If there is any liquid in the tank at all, it will maintain the standard CO2 pressure for the given temperature. The only way there would be less pressure, is if there is no liquid and less than maximum gas for the volume of tank. I doubt that is so, or the tank setup would be the same as a bulk air fill starting at only 850psi or less.

I'd be more inclined to believe the calibration for the gauges are off.

there are 3 types (iirc) of macro. 1-1200-1500 psi working (iirc), 2- 400-500 ish (iirc) and the last one is rated to 3 k (again iirc). just make sure to check what the line has printed on it. the mid psi one should be fine. my friend runs his mag at 1000-1400 psi through long pieces of macro to get to the valve and its fine. everyone acts like co2 works like acid on macro, it doesnt just as long as you make sure you dont leave the gun in heat or over fill your tank you should have no more problems than you would have running hpa.


even with macro your suposed to swap it out once a year, i played about every other or every 3rd weekend for about a year and a half the continued playing here and there the next 6 months with it and i never had a leak or blow out (knock on wood so the neck time i pull it out it doesnt go crazy)



in short get the right rating for it and your fine
