Scuba tanks are not just another piece of gear—they are the heart of every dive. Choosing the wrong brand could mean risking safety, comfort, and even the success of your diving trips. I have worked with countless suppliers and brands through my own experience in the gas cylinder industry. After years of testing, sourcing, and speaking with dive shop owners worldwide, I can confidently share which brands are truly worth your trust.
If you are a retailer, distributor, or professional diver looking for reliable scuba tanks for 2025 and beyond, this list will save you a lot of trouble.
Over the past decade, I have been deeply involved in the B2B gas cylinder industry. I have helped diving shops, sports gear distributors, and adventure travel companies choose the right scuba tanks for their business. I work closely with factories and know exactly what makes a tank safe, durable, and worth investing in. When I recommend a brand, it is not based on popularity—it is based on real performance, international certifications, customer feedback, and production quality.

Catalina Cylinders is a name you see everywhere for a reason. They have been making aluminum scuba tanks in the U.S. for over 30 years. Their tanks are lightweight but incredibly tough, with DOT and TC approvals. I always recommend Catalina for businesses that prioritize easy handling and consistent quality. Plus, they offer great customization options if you are planning to build your own brand.
Catalina uses a proprietary aluminum alloy that resists corrosion better than many competitors. In saltwater diving conditions, this means a much longer lifespan. Many dive shops tell me their Catalinas are still going strong after 10+ years with regular inspections. If you are looking for a safe and cost-effective choice for rental fleets, Catalina is hard to beat.
Luxfer is another industry giant. Based in the U.K. and the U.S., they focus on performance under extreme conditions. Their scuba tanks are famous for being slightly lighter than Catalina, which matters a lot when divers are carrying multiple tanks or dealing with long walks to the dive site.
One of my distributor partners in Australia switched completely to Luxfer tanks last year. Their customers immediately noticed the weight difference. For technical diving, especially deep or cave diving, every kilogram counts. Luxfer also offers an eco-friendly manufacturing process that reduces carbon footprint—an important selling point today.
Made in Italy, Faber specializes in steel scuba tanks. If you need higher working pressures (like 300 bar/4350 psi), Faber is the way to go. Their steel tanks have excellent buoyancy characteristics, making dives more balanced and controlled.
I once toured Faber’s production plant in Cividate al Piano. Their attention to material sourcing and cylinder integrity was incredible. Every tank undergoes multiple stages of ultrasonic and hydrostatic testing. In cold waters like Scandinavia and Canada, dive shops almost always prefer Faber because of the better weight distribution compared to aluminum tanks.
Worthington was once the go-to American brand for steel scuba cylinders. Though they have exited the scuba cylinder market recently, you can still find a lot of their tanks in circulation, especially in North America. They built a reputation for durable, heavy-duty tanks that withstand rough usage.
If you see a used Worthington tank for sale with recent hydro testing, it is usually a good investment. Many rental shops still use Worthingtons because they can survive constant fills, drops, and ocean exposure without major issues.
Norris specializes in high-pressure gas cylinders. Although they are better known in industrial circles, they offer a few scuba models that are worth considering for niche markets, especially for deep diving or mixed gas applications.
I had a client who needed custom cylinders for a technical diving training center. Norris was able to supply special specs that standard scuba brands could not. If your business needs custom solutions for specialized diving, Norris is a hidden gem.
Another Italian manufacturer, San-o-Sub focuses on both steel and aluminum scuba tanks. They are less known outside Europe but offer excellent price-to-performance ratio.
One thing I like about San-o-Sub is their flexibility. Small batch orders, private label opportunities, and a variety of finishes make them attractive to start-up brands. I have recommended San-o-Sub to several small diving gear companies who wanted to create their own line of branded tanks.
