Side-by-side spec comparison of up to three scuba cylinders. Pick by manufacturer & model, filter by material or capacity, and switch between imperial and metric units.
Data based on manufacturer specifications compiled by T. Massey (Feb 2024) from Catalina, Luxfer, Metal Impact, Faber, OMS, PST, and Worthington; supplemented with Thunderbird Cylinders specs (2025). “Actual capacity” is computed from each cylinder's water volume and working pressure, and may differ from the marketed “full air capacity” by a few percent.
