GFSP Outdoor Sports CO2 Cylinders Tank Soda Thread to W21.8-14 Converts Adapters

It fits the soda stream bottle but it is not the same thread as a paintball cylinder fill station if thats what you are trying to go for

Shipped fast! Just what I needed to convert soda stream to co2 regulator. Great for aquariums!!!!

Make thread fits nothing in the US of A!!!Had to re-thread the end.
