12 L Scuba Tank: Reliable High-Pressure Cylinder for Diving & Oxygen Supply
If you're sourcing a 12 L scuba tank for commercial diving, oxygen therapy, or industrial gas storage, you need a cylinder that meets strict safety standards, offers consistent pressure, and fits your supply chain timeline. This guide covers technical specifications, compliance certifications (DOT / ISO), MOQ, lead time, and OEM options—everything an import manager or brand owner evaluates before placing an order. Backed by a Chinese factory with over 10 years of gas cylinder expertise, we deliver high-speed delivery without compromising quality.
Industry Pain Points in Sourcing a 12 L Scuba Tank
Importers and wholesalers often face three major challenges when buying high-pressure cylinders:
- Unclear certification compliance – Many suppliers claim “CE/ISO” but lack verifiable DOT or ISO 9809-1 approvals for the US market.
- Inconsistent quality control – Wall thickness, neck thread precision, and valve sealing vary batch-to-batch, leading to higher rejection rates.
- Long lead times & poor communication – Production delays and unclear shipping terms (FOB/CIF) disrupt inventory planning for distributors and filling stations.
A reliable partner must provide transparent data, third-party certifications, and realistic delivery schedules.
Why Our 12 L Scuba Tank Is the Solution
At Zhuzhou XingYe Chemical, we manufacture high-pressure steel cylinders specifically designed for scuba diving and oxygen storage. Our 12 L scuba tank is produced under strict ISO 9001 quality management and tested per DOT-3AL and ISO 9809-1 standards. Each cylinder features:
- Working pressure: 200 bar / 20 MPa (standard for scuba) – also available at 300 bar for specialty use.
- Water capacity: 12.0 L ± 0.5 L, with external volume approx. 2.3–2.5 L (depending on steel grade).
- Weight: approx. 14.5 kg (empty) – lightweight compared to older 10L/12L models, thanks to high-strength alloy steel.
- Valve connection: standard 5/8″ UNF neck thread for DIN or yoke valves.
- Finish: durable light grey or blue painted epoxy coating – can be customized with your brand logo.
Every cylinder passes hydrostatic pressure testing at 150% of working pressure, plus sonication or magnetic particle inspection to detect micro-cracks.

Compliance & Certifications for US Import
To sell scuba tanks in the United States, cylinders must meet DOT (Department of Transportation) requirements – specifically DOT-3AL (aluminum) or DOT-3AA (steel). Our 12 L tank is manufactured in accordance with DOT-3AL specification for low-temperature service and ISO 9809-1 for seamless steel cylinders. Additionally:
- ISO 9001:2015 – Quality management system from raw material to final testing.
- CE (Pressure Equipment Directive 2014/68/EU) – Required for EU/UK but accepted as additional safety standard.
- Sonication test and ultrasonic thickness measurement on 100% of production.
- Batch traceability – Each cylinder laser-marked with UN, serial number, and manufacturing date.
We can provide a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) for the gases used during testing. For US import, we also assist with shipping documentation for DOT required labeling.
MOQ, Lead Time & OEM/ODM Support
Minimum Order Quantity (MOQ): 50 pcs per size/color (can be mixed with other tank sizes for containerized orders).
Lead Time: Production takes approximately 25–30 days after sample confirmation. For urgent orders (up to 200 pcs), expedited delivery in 15–18 days is available at a 5% surcharge.

| Scuba Diving (Recreational / Technical) | Common in tropical resort rentals – easy to handle, enough for 45–60 min dive at 18m. |
| Oxygen Therapy & Medical Use | Used in clinics, homecare, emergency services – 12L medical oxygen tank. |
| Industrial Gas Storage | Storage of compressed air, nitrogen, or argon for workshops & labs. |
| Firefighting & SCBA | Compact enough for short-duration breathing air packs. |
What Our Customers Say
“We imported 200 units of the 12L scuba tank for our dive center in Florida. The DOT-3AL certification was spot-on, and the tanks passed hydro inspection without a single failure. Lead time was 28 days, as promised.”
Mike Hannigan – Diventures LLC (USA)
“Excellent OEM service – they printed my brand logo exactly to the Pantone color and provided COA for each batch. The 12L tanks are now part of our medical oxygen rental fleet.”
Sarah Lin – Oxygen Solutions Ltd (Australia)
