Producer
Catalina Cylinders
Garden Grove, California-based US aluminum cylinder manufacturer. One of the three principal US manufacturers of aluminum medical oxygen cylinders, alongside Luxfer and Worthington. Catalina Cylinders produces DOT 3AL-certified aluminum cylinders (aluminum alloy 6061-T6) in medical oxygen sizes for hospital, EMS, home health, and industrial use. Catalina also manufactures aluminum cylinders for scuba diving, paintball, compressed air, and industrial gas applications — the full range of DOT 3AL high-pressure aluminum cylinder types. Catalina is a privately-held US company, providing domestic supply chain diversity vs. Luxfer (UK-owned). Catalina cylinders are used by oxygen filling companies (Airgas, Praxair/Linde) and home medical equipment providers. Unlike Luxfer and Worthington, Catalina focuses almost exclusively on aluminum cylinders rather than composite or steel. Historically manufactured the bulk of US aluminum SCUBA and medical cylinders.

Did you know2024
Catalina's medical oxygen cylinders and paintball CO2 cylinders are manufactured on the same production line using the same DOT 3AL-certified aluminum alloy (6061-T6) and the same hydrostatic pressure testing protocol — only the valve fitting, size, and labeling differ by application. The aluminum cylinder for a COPD patient's home oxygen concentrator and the aluminum cylinder for a paintball enthusiast's CO2 hopper are the same product. This means that: (1) a shortage in medical oxygen cylinder demand can be partially offset by recreational cylinder inventory; (2) a raw materials shortage (6061-T6 aluminum extrusions) simultaneously affects healthcare supply chains and leisure goods supply chains; and (3) the manufacturing bottleneck for medical oxygen delivery infrastructure is the same facility making paintball cylinders.
Catalina Cylinders ↗Chokepoint2024
Catalina Cylinders is the only significant privately-held, US-owned aluminum medical oxygen cylinder manufacturer — providing supply chain diversity against Luxfer (UK-owned/publicly traded) and Worthington (Ohio/publicly traded). However, Catalina operates from a single facility in Garden Grove, California (Orange County). A facility-level disruption — fire, earthquake (Garden Grove is in the seismically active Elsinore Fault zone), or regulatory shutdown — would eliminate Catalina's entire production capacity instantly, with no backup facility. As the third-largest US medical cylinder manufacturer, Catalina's single-site structure means that any disruption to Orange County industrial real estate (flood, fire, earthquake, or contamination event) tightens the US medical oxygen cylinder market by ~12% with no Catalina-owned fallback.
Catalina Cylinders ↗Origin2023
Catalina Cylinders was established in Garden Grove, California as an aluminum high-pressure cylinder manufacturer serving the Southern California industrial and aerospace market. The company grew by applying the DOT 3AL aluminum cylinder standard (6061-T6 aluminum alloy) to multiple gas storage applications with the same manufacturing process — medical, SCUBA, industrial, and recreational cylinders all use the same core metallurgy and pressure testing. Catalina became one of only three US domestic manufacturers of medical oxygen aluminum cylinders alongside Luxfer and Worthington, an oligopoly that became a recognized healthcare supply chain risk.
