Flatline Reg. Maintenance.

[ah137]

i have a 4500 flatline thats set to 750 and it drops to about 450, needless to say its will not fire my emag with any kind of rate of fire. I am guessing the reg seat is shot. But it looks like its in good shape? I also noticed it makes a whin when its recharging.

Thanks Hills


P.S. you should see if you can get a pic of an exploded 4500. check next post! for pic

Ok, I believe I figured it out

The 4500 flatline reg body MUST match up on the reg base (tank side).

P.S. your tank does not have to be empty to rebuild/clean the reg.

Hissing Reg

Hi there!

I bought a used Mag with a flatline 3000 psi Regulator. The gun has been used five times so its quite new. As I filled the tank for the first time today I noticed a slight hiss coming out of the regulator body somewhere near the LP clock. I closed the on/off valve and whitnessed that the pressure indicated at the LP clock dropped rapidly from 800 to 0 in about two minutes, while the pressure indicated at the HP clock remained quite the same. Now the LP pressure is down to 0 but I still can hear the hissing. I have noticed, too, that the HP clock is not screwed down into the body as much as the LP clock. Could that be the problem? Is it possible that air leakes through the thread of the HP clock?

I am quite sure that the leak must be somewhere near the two clocks. I checked the whole reg body holding my lips about 1 cm over the surface and I noticed the air escaping on that position. Any suggestions?

It could very well be the gauge. If you air it up again spray the area with soapy water and look for bubbles. If it's coming form arounf the threads then remove the gauge, clean the threads and screw it back on using the yellow gas fitting tape or non-permanent locktite. Hopefully that will stop it from leaking.

Update
Update- I replaced the reg seat and made sure the reg body was tight. Fixed!

I do not suggest taking apart the 4500 flatline and removing the reg seat unless you replace the reg seat
with a new one. Long and short of it; if you rebuild your
reg put in a new reg seat every time.

I didn't like the dove tail style drop so I took it off and drilled my shocktech so it would accept the 4500 flatlines two hole pattren.

The drop can still be used on a dove tail.

Hi from Greece.
A problem with the Flatline 3K reg. When i open the on/off very low pressure is coming from the bottle, about 200 psi.
The bottle is filled with 3000 psi of course.
I tried many times the on/off movement,but nothing! The same problem.
Any suggestion? Thank you.

[rikkter]

in the very front of the tank.. theres a silver piece with a hex hole in it, just adjust that and it'll go up

[Hellaspaint]

It is not a problem of adjustment of the output pressure. The pressure is very-very low and the same: ~200 psi, wherever i adjust the regulator.

ah137- I've come to the same conclusion as you. Whenever I take apart a 4.5K Flatline, I always replace the reg. seat. Otherwise, I get horrible shootdown.

Hellaspaint- If tightening the adjuster on the front side of the reg doesn't change anything, then make sure the entire reg. body is tight. Take off the mounting clamp and you'll see four holes around the reg. body. Stick an allen wrench in one of those holes and tighten it up. Try that. If that doesn't work, then take it all apart and clean and oil it. Make sure that the safety ball isn't stuck. It's the silver ball in the back half of the regulator in the center hole that you'll see when you take off the front regulator body.

[edit: Never mind.]

[vortechcoupe]

ok, i have a 68/3K flatline. The problem is when the tank is full i'll set the output pressure at lets say 900, but when the tank press drops the output does also graduly with the tank pressure. I put a new reg seat in, which it already had a new one but it didn't change anything. Should i replace the piston oring? Thanks for any help.

[Hellaspaint]

Thank you BlackVCG for your post. Finally i fix it by taking off the on/off shaft and clean it.
Do you know if the Flatline 3000 psi is still in production.
Happy new year with nice and safe games for all members.

Leaks how fast? I played last Saturday and my Flatline was at 3k when I left but when I checked it today it was empty. I'm not sure how fast it emptied so I was wondering what's the average time it should hold a fill?

[BlackVCG]

It should hold the fill for months. It should NOT drain a tank that quickly. Take the tank, fill it, take it off the gun and then stick it in a bucket of water. Check to see where air bubbles are coming from. Chances are the gauges or fill nipple threads aren't sealed properly and they're leaking.
