AIR IN DOS CANT STOP IT.

Has anyone ever found a permanent fix to air in the lines ? I believe it comes from the ddr fittings.
Looking for some new ideas , thanks.

No I have not. I don’t think the air is coming from there , I think it’s from the ddr connections that use the same fittings as you described.
When I attempt to unscrew ddr fittings on #2 the acrylic tube spins with it.

Ahh gotcha. That’s possible, never had mine leak with those types of fittings but maybe someone with a DDR can chime in. The DOS is notorious to have air leaks at their connectors as well.
