Barely 1 Kg

Air Regulator

Adjust to Your Needs

It allows you to adjust the air flow according to your needs underwater, thereby maximizing the autonomy of your tank.

Multiple Configurations

For a Total Freedom

Use the tank directly in your mouth, or with an external regulator to wear the tank on your back for even more freedom of movement !

The OX500Plus, while retaining the compactness and 5 to 8 minutes of autonomy of the classic OX500, brings advanced features for an enhanced underwater experience. An adjustable air regulator allows you to modulate the air flow according to your needs, optimizing autonomy and minimizing the risk of leaks. Thanks to the external pressure gauge, you can check the remaining air level without removing the tank from your mouth, with the option to choose between this and the standard pressure gauge.

The OX500Plus stands out with its dual functionality: you can use the classic mouthpiece or opt for an external regulator for a diving experience similar to that with the OX1000. For comfortable use of the external regulator, a back harness is included, offering greater comfort and increased freedom of movement.

Included Accessories

The OX500Plus tank comes with a range of carefully selected accessories to ensure an exceptional experience right out of the box.


Enhance your diving experience with our premium silicone mouthpiece. Designed for optimal comfort, it fits perfectly, stabilizing the tank while allowing free movement. Its soft texture and ergonomic design enable extended use without discomfort, allowing you to focus on underwater exploration.

The Storage Bag

Transport and protect your OX500 tank with our specially designed storage bag. This stylish and practical bag provides optimal protection for your Oxsea equipment, making it easy to carry wherever you go. It’s an essential accessory for any diver wanting to keep their equipment in perfect condition.

Pressure Gauge

Our pressure gauge is an essential tool for any safety-conscious diver. It provides a clear and accurate reading of the remaining pressure. Its robust design and ease of use allow you to manage your air supply effectively and reliably.

External Pressure Gauge

Our external pressure gauge, essential for safety-conscious divers, easily attaches to your tank for precise pressure measurements. With a flexible hose, monitor your air supply without removing the mouthpiece. Robust and practical, it ensures a safe diving experience.

External Regulator

The OX500Plus is the only Oxsea tank that offers dual usage. In addition to the standard OX500 mouthpiece, it allows you to connect an external regulator, so you don’t have to hold the tank directly in your mouth. You can use your tank directly like the classic OX500, or connect your external regulator and use it like the OX1000 tank.

Back Harness

Of course, if you use the external regulator, we have designed a harness to wear your tank on your back. This harness ensures you won’t be hindered or encumbered during use.


Never lose your diving tank again with our wrist strap. Designed to securely attach to your cylinder and wrist, it provides extra safety underwater. Lightweight and durable, it’s an essential companion that keeps your tank within reach at all times, offering peace of mind and freedom of movement.
