Air Leaking out my 4.5k Flatline when it is off?

[AirChunck]

When I put air in my 4.5k flatline, it leak out of the port to which I attach my macro-line when the valve is turned off. Any recommendations?

Thanks

i dont know much about the flatline, but check your macro fittings. tighten them or use teflon tape on them. also, check your macro hose where it goes into the fitting, make sure its not knicked or anything.

Check the Flatline maintenance thread, it should be stickied in this forum.

I had the same problem a few months ago. I rebuilt the Flatline reg and replaced the reg seat.

If you have the 4500 Flatline, this is the part you'll need:
