Scuba Oxygen Cylinder – High‑Purity Breathing Gas for Professional Diving & Commercial Use
Are you sourcing scuba oxygen cylinders that meet U.S. safety standards, offer consistent purity, and can be delivered on time? At Zhuzhou XingYe Chemical, we manufacture and supply high‑pressure oxygen cylinders specifically designed for underwater breathing applications. With over 10 years of expertise, a dedicated factory, and full compliance with international certifications (ISO, DOT, CE), we help import managers, brand owners, and wholesalers get reliable oxygen cylinders with flexible OEM support, competitive pricing, and express shipping from China. This page covers everything you need to know about our diving oxygen tanks – from technical specs to ordering details.
Common Challenges When Sourcing Scuba Oxygen Cylinders
Buyers in the diving industry often face three major pain points:
- Inconsistent gas purity – low‑grade oxygen can cause health risks or equipment damage.
- Unreliable delivery schedules – delayed shipments disrupt inventory planning.
- Lack of certification compliance – many suppliers cannot provide DOT, CE, or ISO 9001 documentation needed for import.
- High minimum order quantities – inflexible MOQ limits small‑scale testing and new product launches.
These issues lead to increased costs, safety liabilities, and lost business opportunities. A trusted manufacturing partner with end‑to‑end control over production and quality is the solution.
The Solution – Zhuzhou XingYe Chemical Scuba Oxygen Cylinders
Our scuba oxygen cylinders are filled with medical‑grade oxygen (≥99.5% purity) and housed in high‑strength steel or aluminum cylinders that comply with DOT‑3AA / DOT‑3AL and EN 1964 standards. Each cylinder undergoes rigorous hydrostatic testing, valve inspection, and gas chromatography analysis before shipment. We supply sizes from 2L to 80L with working pressures of 200 bar / 3000 psi, suitable for recreational diving, commercial diving, military use, and underwater welding.
Whether you need a private‑label product, a specific valve connection (CGA 540, DIN), or special cylinder coatings, our OEM/ODM capabilities ensure your exact requirements are met.
