$25 - One American Sanke coupler with about 4.5' of Bevlex attached to it.
$10 - 1/4" barb Ball lock gas disconnect and liquid disconnect and about 4.5' of Bevlex.
$45 - 5lb CO2 tank with regulator - Full. I think it is steel. I exchanged an empty tank and Praxair and received this.
The picture shows the pin lock attached to the gas tubing, but obviously I will separate them unless you want both.
I can ship the couplers and add the shipping to the price of the item.
I would prefer local pickup for the CO2 tank - I just don't like the idea of shipping a pressurized gas cylinder.
I am in the Augusta, GA area.
