Oxygen Consumption & Cost Calculations
What are the commonly encountered oxygen connector types?
- Large J size (6800 L) oxygen cylinders (filled at 137bar/~2000psi) commonly have a Bull Nose (BS 341) oxygen outlet. Many smaller cylinders have the same outlet. Pin Index cylinders (ISO 407) may be unavailable in some resource variable settings.
- A regulator with Bull Nose connector attaches to the tank to decrease the pressure from 137bar/2200psi to ~4 bar/50psi
- Regulator outlet connectors vary (4 bar) high pressure connectors are 1/4” hose outlet, 3/8” BSP or Shrader (BS 5682) quick release (left to right in image).
