I recently was discussing Macroline with Tunaman and he claimed he had awsome MacroLine. I had always thought that Macroline, and esp the fittings were not good for PB use due to their low pressure ratings. Tuna offered to send me a couple of fittings and some hose to try out. I got the package a couple of days later and looked at the hose: "Parker Parflex 1/4 OD x .062 wall 500 WP..." I though: "oh no! more junk to break. a 500psi working pressure." Well he gave it to me so i may as well test it....
Heres the test i devised. seeing how i work at a pb field, i have a N2 system. I removed the SS line that we use to fill taks and replaced it with the parker macroline and fittings. I then reattached the female QD to the macro. I own a 4500psi DynaFlow, so i can pump the pressure up to 4500psi. I wanted the hose to hold 1800psi, as that is the burst disk rating on a nitro tank.
I quickly hooked up the tank and turned the pressure to 500psi-- the working pressure. i have an oil gauge on my sstation, so i am accurate to 1%. I then bumped it to 600psi and let it sit for 1 minute. Then 700. 1 minute. 800. 900. 1000. at around 30 seconds, a small leak started from the fitting on the fill station end. i then at hte end of the min, bumped it to 1050psi. waited a min, bumped to 1100psi. No larger leak, but it was still there. i then bumped it to 1150psi. then 1200psi. the leak started to get larger...but it was still a small hiss(i didnt get my head to close to the fitting for obvious reasons to see just how loud it was). then 1250. after around 45 seconds here the leak got larger. i then bumped it to 1300psi and as it got to aound 1300psi, the fitting blew apart.
So, conclusions? Im pretty happy with it. 1300psi is surely safe if you are running your tank at good paintball presures, however if the tank were to fail and it were to stop regging the air, you would blow a fitting before the tank's burst disk blew, which is not a good thing. But, i now have some faith in this macro setup, and am now ordering a bunch of this macro from Tunaman to sell at my store.
thanks for reading, and Macro now has one more supporter...
