1.5 L Scuba Tank: A Compact, Reliable Oxygen Cylinder for Divers, Emergency Preparedness, and OEM Applications
If you are sourcing a 1.5 L scuba tank for wholesale, OEM branding, or import distribution, your primary questions likely revolve around certification compliance (DOT/ISO), working pressure, MOQ, lead time, and whether a Chinese factory can deliver consistent quality at scale. The 1.5-liter format is widely used as a pony bottle for emergency air supplies, a compact oxygen cylinder for enriched air diving (Nitrox), or a portable gas source for first-responder medical kits. This guide provides a transparent, data-backed look at the specifications, certifications, and sourcing terms you need to evaluate before placing an order.

Why Sourcing a Small Scuba Tank Is Harder Than It Should Be
Import managers and brand owners who purchase small-format scuba cylinders in volume often encounter three recurring frustrations:
- Inconsistent valve threading and pressure ratings — Some factories ship cylinders that do not match U.S. or European valve standards (DIN vs. Yoke), causing costly rework.
- Unreliable hydrostatic test documentation — Without proper ISO 9809 or DOT-SP 10915 traceability, cylinders cannot be legally filled at dive shops in North America.
- High minimum order quantities (MOQ) for small-size tanks — Many suppliers refuse to run small-diameter cylinders unless the order exceeds 2,000 units, locking out mid-tier buyers.
A 1.5 L scuba tank occupies a niche between a full-size backmount cylinder and a disposable oxygen can. It must meet the same safety standards as larger tanks, yet its small diameter and lightweight construction require specialized drawing and forming tools. Without a factory that owns dedicated tooling for small cylinders, you risk dimensional inconsistencies and certification delays.
The 1.5 L Scuba Tank from Zhuzhou XingYe Chemical — Built for Commercial Reliability
We manufacture our 1.5 L scuba tank from high-strength 6061-T6 aluminum alloy, using a deep-draw process that ensures uniform wall thickness. Each cylinder is designed to serve as a diving oxygen cylinder for enriched air (up to 40% O₂) or as a pure oxygen source for decompression and emergency breathing systems. Below are the key technical parameters:

| Working Pressure (WP) | 200 bar / 3,000 psi |
| Test Pressure (TP) | 300 bar / 4,500 psi |
| Gas Capacity (Air at 200 bar) | Approx. 300 L |
| Outside Diameter | 102 mm (4.0 in) |
| Length (with valve) | 365 mm (14.4 in) |
| Empty Weight | 2.4 kg (5.3 lb) |
| Material | 6061-T6 Aluminum Alloy |
| Valve Connection | 3/4" NPSM (DIN 477 compatible) / Yoke adapter available |
| Hydro Test Cycle | Every 5 years per DOT / ISO 9809-1 |
| Service Life | 15 years from date of manufacture (aluminum) |
All specifications are nominal and subject to final engineering approval. Please refer to the actual order confirmation and factory test certificate for lot-specific values.

Certifications & Compliance — What Ships With Your Order
Every 1.5 L scuba tank leaving our factory is accompanied by a traceable certification package. For the U.S. market, we ensure compliance with the following frameworks:
- ISO 9809-1 / ISO 9809-3 — International standard for refillable seamless gas cylinders. Our aluminum cylinders are designed and tested to these norms.
- DOT-SP 10915 — Special permit for aluminum cylinders imported into the United States. We can supply cylinders stamped with DOT 3AL or DOT-SP markings upon request.
- CE (PED 2014/68/EU) — Pressure Equipment Directive certification for European-bound shipments. Category I/II modules available based on volume.
- COA (Certificate of Analysis) — For oxygen service, we provide gas purity analysis showing ≥99.5% O₂ (medical grade) or ≥99.2% (diving grade).
- MSDS — Material Safety Data Sheet for compressed oxygen, compliant with OSHA HazCom 2012 (GHS).
- ECM (European Conformity Module) — Provided for CE-marked cylinders, verifying production quality assurance.
Please note: Certification requirements vary by destination country and end-use. It is your responsibility as the importer to verify that the specific marking (DOT 3AL, ISO, or PED) matches your local regulations. We will support the documentation required, but we recommend engaging a local pressure vessel consultant for final approval.

What Our Customers Say About the 1.5 L Scuba Tank
Mike Thornton
Operations Manager, Atlantic Dive Supply (Florida, USA)
"We imported 1,200 units of the 1.5 L tanks for our pony bottle rental program. The DOT 3AL stamping was clean, the hydro paperwork was in order, and the anodizing consistency was better than our previous supplier in Italy. Lead time was 32 days from sample approval — they kept their word."
Sarah Chen
Sourcing Agent, Pacific Rim Procurement (California, USA)
"I have been sourcing gas cylinders from China for 8 years. XingYe is one of the few factories that understands the paperwork requirements for U.S. import. They provided the DOT-SP documentation, the COA, and even helped me get the cylinders listed on the DOT website. The 1.5 L tanks are selling well in our emergency preparedness catalog."
James O'Donnell
Brand Owner, O'Donnell Dive Gear (Ireland)
"We needed a 1.5 L cylinder with our brand logo in a specific RAL blue. The sample matched the Pantone exactly. The CE certification documents were submitted with the batch, and our local notified body accepted them without questions. Pricing was competitive — about 15% below our Turkish supplier."
David Reyes
Procurement Lead, West Coast Oxygen Supply (USA)
"We use the 1.5 L tanks for medical oxygen in remote first-responder kits. The valve threading was consistent across all 500 units, and the O-ring quality held up during our internal leak test. Shipping via FOB Shanghai was smooth — the factory handled the container loading and provided photos."
Rita Navarro
Import Manager, DiveWorld Trading (Australia)
"The MOQ of 200 units for the 1.5 L tanks was perfect for our test run. We ordered with DIN valves and yellow anodizing. The hydro test certificates were emailed ahead of the shipment, which helped us clear customs in Melbourne within 3 days. Repeat order placed."
Common Use Cases for the 1.5 L Scuba Tank
Understanding where this cylinder fits in the market helps you position it correctly for your customers:
- Pony bottle for recreational divers — A 1.5 L tank provides roughly 3–4 minutes of emergency air at depth, enough to perform a controlled ascent from 30 meters. Its small size clips easily to a BCD.
- Enriched air (Nitrox) blending — Dive shops use small aluminum cylinders as blending tanks for oxygen. The 1.5 L size is manageable for countertop blending stations.
- Emergency preparedness kits — Civil defense and remote site medical kits often include a 1.5 L oxygen cylinder with a regulator for on-site oxygen therapy.
- Oil and gas industry calibration — The cylinder is used as a portable calibration gas source for portable gas detectors in confined-space entry.
- Airsoft and paintball — Some high-end airsoft systems use compressed air from small scuba tanks as a source for HPA (high-pressure air) adapters.
