CO2 Leak Between Needle Valve and JBJ Bubble Counter

[DGalt]

So my system is almost put together (finally, after many setbacks). There is still one small hitch though.

I'm using a Swagelok metering valve with male compression BPT adapters so that I can attach it to my solenoid and JBJ bubble counter.

The connection between the metering valve and the solenoid is fine. However, there is an air leak between the adapter and the bubble counter. I can't tighten the counter any more onto the metering valve, so is there anything else I can do to stop this leak?

thanks

small amount of vaseline to help it seal? I'd take it apart and inspect the mating surfaces.


anything that is NOT a compression fitting should probably have some teflon tape on it (?)
