Second Hand Re tested 3.5kg co2 bottles for
mig welders, they come full of gas and are refillable.
These have new certification stamps on them
I can fill all co2 bottles, paintball,fire extinguishers, etc.
I also have co2/argon gauge adapters.
These cylinders are NZ certified.
Suitable for beer kegging, fish tanks, mig welding, Paint ball bulk tanks (includes free siphon tube) If you want this for paintball refilling you need to tell me so I can install a siphon tube.
I also sell New 5 kg co2 Cylinders
I don't do argon bottles

Note:
All co2 bottles must be grey in order for them to be NZ certified for welding, paintball, kegging, fish tanks etc. (excluding Fire Extinguishers)
