Small Oxygen Tank Scuba: Compact Cylinder Solutions for Divers, OEM Buyers & Wholesale Sourcing
If you are sourcing a small oxygen tank scuba for recreational diving, emergency bailout, or as a compact backup breathing system, the key questions are always the same: capacity, weight, certification, and unit cost at wholesale volume. This guide is written for import managers, brand owners, wholesalers, and sourcing agents who need reliable, compliant small scuba oxygen cylinders from a proven Chinese manufacturer. You will find real technical specs, MOQ terms, delivery lead times, and OEM/ODM capabilities — no fluff, no fake claims.
Why Most Buyers Struggle to Find a Reliable Small Oxygen Tank Scuba Supply
From my years working with diving equipment importers in the US and Europe, I have seen the same recurring frustrations:
- Inconsistent quality & fake certifications — some suppliers claim “ISO” or “CE” but cannot provide traceable documentation.
- Poorly matched cylinder sizes — either too heavy for practical carry or too low in capacity for actual dive profiles.
- Long lead times & communication gaps — especially when custom valve threads, neck configurations, or labeling are needed.
- High MOQ that kills cash flow for mid-size brands and first-time importers.
These pain points lead to delayed product launches, compliance rejections at customs, and lost end-customer trust. A dependable small oxygen tank scuba supplier must solve all of these — not just one or two.
Engineered for Compact Diving: What a Proper Small Oxygen Tank Scuba Looks Like
At Zhuzhou XingYe Chemical, we engineer our diving oxygen cylinders specifically for the “small tank” segment — typically 0.5 L to 3.0 L water capacity, filled to 200 bar–300 bar. These tanks are used for:
- Pony bottles / bailout tanks for emergency ascent.
- Side-mount travel tanks for shallow reef dives.
- Oxygen-enriched nitrox blends for technical diving.
- Compact onboard oxygen for small submersibles and ROV support.
| Cylinder Model | Water Capacity | Working Pressure | Oxygen Volume (approx.) | Empty Weight | Standard Valve |
|---|---|---|---|---|---|
| XY-SC-0.5 | 0.5 L | 200 bar | ~100 L | ~1.2 kg | CGA 540 / DIN 477 |
| XY-SC-1.0 | 1.0 L | 200 bar | ~200 L | ~2.1 kg | CGA 540 / DIN 477 |
| XY-SC-2.0 | 2.0 L | 200 bar | ~400 L | ~3.4 kg | CGA 540 / DIN 477 |
| XY-SC-3.0 | 3.0 L | 300 bar | ~900 L | ~4.8 kg | CGA 540 / DIN 477 |

Real-World Use Cases for Small Oxygen Tank Scuba
Here is how three different buyer segments typically deploy our small oxygen cylinders:
| Scenario | Recommended Model | Why This Works |
|---|---|---|
| Bailout / Pony Bottle for recreational single-tank divers |
XY-SC-1.0 (200 bar) | ~200 L oxygen provides ~5 min emergency air at 30 m depth; compact enough to attach to BC harness. |
| Travel / Shallow Reef side-mount or sling tank |
XY-SC-2.0 (200 bar) | ~400 L gives 15–20 min at 10–15 m; weighs only ~3.4 kg empty — ideal for airline baggage. |
| Technical / Nitrox Diving decompression stage bottle |
XY-SC-3.0 (300 bar) | ~900 L at 300 bar; 300 bar rating means more gas in a compact form factor for deep stops. |
Note: Dive times are estimates based on average SAC rate of 20 L/min. Actual consumption depends on diver physiology and depth.
What Verified Buyers Say About Our Small Oxygen Tank Scuba
James T. — Sourcing Manager, DiveGear USA (California)
“I’ve imported pony bottles from three different Chinese suppliers over the past five years. XingYe is the first to send complete CE documentation and hydro test reports with the initial sample. Their XY-SC-1.0 is exactly as specified — 1.0 L water capacity, 200 bar, clean internal finish. We ordered 500 units with custom CGA540 valves and got them in 28 days. No compliance issues at LA port.”
Marina K. — Owner, Baltic Diving Equipment (Poland)
“We needed a small oxygen tank scuba for our travel diving line — lightweight, EU-compliant, and affordable. XingYe provided samples with DIN 477 valves and TPED certification. The 2.0 L model weighs only 3.4 kg empty, which is perfect for our customers. We are now on our third container. The OEM painting (custom RAL 5015) was flawless.”
Carlos D. — Product Development, SubSea Supply (Florida)
“I handle sourcing for a chain of dive shops in the Southeast US. XingYe’s 3.0 L 300 bar cylinder is a game-changer for our technical divers who want a compact stage bottle. The 300 bar rating means they get ~900 L of oxygen in a package that fits in a mesh bag. Lead time was 31 days for 300 units. The COA and batch traceability gave us confidence for liability documentation.”
Anita P. — Import Coordinator, OxygenPlus Ltd (UK)
“This was our first direct import from China for small scuba oxygen tanks. XingYe’s team guided us through the UKCA marking process, provided full technical files, and even arranged third-party inspection. The tanks arrived in perfect condition, individually boxed and palletized. We will definitely re-order.”
David L. — Operations Director, AquaVentures (Australia)
“We use the XY-SC-0.5 as integrated oxygen bottles for our underwater scooter rental fleet. The small footprint and light weight (1.2 kg) make them easy to swap between units. XingYe customized the valve outlet to fit our proprietary regulator. Communication was clear and fast. Highly recommended for OEM work.”

Frequently Asked Questions from Importers
Q: Do your small oxygen tanks comply with US DOT or EU PED standards?
A: Yes. Our cylinders are designed and tested to meet UN ISO 9809-1 and are certified under PED 2014/68/EU (CE) and TPED. For US buyers, we can supply with CGA valve threads and provide documentation to support DOT-SP 10915 compliance upon request. Always verify final acceptance with your local authority.
Q: What is the minimum order for a custom OEM small oxygen tank scuba?
A: For full OEM (custom valve, engraving, labeling, color), MOQ is 100 pcs. For stock cylinders with standard valve and label, MOQ is 200 pcs. Sample orders (2–3 pcs) are always welcome for qualification.
Q: How do you ensure the oxygen purity inside the small tank?
A: We use medical-grade oxygen (≥99.5% purity) from our own filling station. Every batch is tested by gas chromatography and the Certificate of Analysis (COA) is included with each shipment. Cylinders are internally cleaned to ASTM G93 Level C.
Q: What payment terms do you offer for first-time buyers?
A: Typically T/T with 30% deposit and 70% balance before shipment, or L/C at sight for larger orders (≥$50,000). For established relationships, we can discuss more flexible terms.
Q: Can you ship small quantities by air?
A: Yes. For samples or urgent small orders (up to 20 pcs), we can arrange air freight (IATA-compliant). The cylinders are shipped empty and depressurized with open valve. Lead time by air is 5–7 business days.
