680 Liter Spare Oxygen Cylinder

Increase the Capacity of Your Current System
Have you purchased a small E-Ox system sometime in the past? Going on an extended cross-country at altitude? You can easily upgrade the capacity of your existing E-Ox system simply by purchasing a new oxygen cylinder. The 680 liter cylinder offers the maximum capacity we offer and is still lightweight and compact enough to be carried in most aircraft. Our E-Ox cylinders and regulators are completely interchangeable so you can "mix and match" regulators with cylinders to fit almost any oxygen need.

Also Useful as a Backup
The 680 liter cylinder is also an effective backup solution to your current oxygen system - whether built-in or portable. When going on long trips at high altitude, carrying a spare oxygen cylinder means you can keep yourself protected from in-flight hypoxia should something happen to your primary system.

Important Note Regarding Shipping:
You may order your E-Ox oxygen cylinders shipped either pre-filled or empty. Pre-filled systems cannot be shipped by air due to federal hazardous materials regulations. Please understand that if you choose to have your bottle filled, we can only ship your order inside the US via USPS Parcel Post. If you select Oxygen Pre-Fill but do not select Parcel Post during checkout, there could be a delay in your order as we will contact you to correct the shipping. Shipping Parcel Post to Hawaii, Alaska or Puerto Rico can take up to and possibly exceeding 30 days.
