2 available. AUS cylinder valves. Same as what you'd buy in the US for regular 3/4" thread scuba cylinders however these don't have burst disc assemblies... so I guess you'll never have to worry about your burst disc rupturing. Best used by someone who has their own fill station and is not worried about being DOT compliant. Use/purchase at your own risk, sold as is. FWIW - these were taken off some AL80's that were in service for the past 10 years or longer... no issues prior to removal.
