If you are sourcing gas cylinders for wholesale distribution or industrial use, the standard size of gas cylinder is not a one‑size‑fits‑all answer. In the US market, cylinders are typically measured by water capacity (liters) or service pressure (PSI), with common sizes ranging from 2.5L to 80L. Whether you need N₂O cream chargers, CO₂ tanks for beverage dispensing, or high‑pressure oxygen cylinders, knowing the exact dimensions, tare weight, and fill pressure ensures compliance with DOT/UN regulations and avoids costly logistics errors. This guide delivers verified specifications, sourcing best practices, and factory‑level insights for import managers and brand owners — so you can order with confidence.
Why “Standard Size” Is a Common Sourcing Pain Point
Import managers and wholesalers often face three recurring headaches when buying gas cylinders from overseas suppliers:
- Inconsistent dimensions — A “standard” cylinder from one factory may not match the racking or filling equipment in your US warehouse.
- Regulatory mismatches — DOT‑spec cylinders require specific wall thickness, valve threads (CGA 580, CGA 320), and hydrostatic test periods that differ from Chinese GB standards.
- Hidden cost variables — MOQ, packaging for sea freight, and certification documentation (ISO 9809, UN markings) can add 15–20% to landed cost if not specified upfront.
At Zhuzhou XingYe Chemical, we have supplied over 500,000 cylinders to North American buyers since 2013. Every unit is traceable to our ISO‑9001 facility, with COA and MSDS included. Below we break down the real standard sizes that matter for B2B procurement.
Standard Gas Cylinder Sizes: Specifications for 2026
The following table lists the most commonly exported cylinder sizes from our factory, compatible with US filling stations and DOT 3AA / ISO 9809‑1 standards. All data is based on production batches shipped to US importers in 2024‑2026.
| Cylinder Type | Water Capacity (L) | Service Pressure (PSI) | Height (in) | Diameter (in) | Tare Weight (lbs) | Typical Fill (lbs) |
|---|---|---|---|---|---|---|
| N₂O Cream Charger (8g / 580g / 615g) |
0.01 – 1.0 L | 1,800 – 2,000 | 2.5 – 10.2 | 1.2 – 3.0 | 0.06 – 0.88 | 0.02 – 1.28 |
| CO₂ Beverage Cylinder | 2.5 – 10 L | 1,800 – 2,400 | 12 – 24 | 4.3 – 6.0 | 6 – 18 | 2.2 – 9.5 |
| Diving Oxygen (O₂) | 7 – 19 L | 2,400 – 3,000 | 18 – 32 | 5.5 – 7.0 | 14 – 30 | 3.5 – 10.5 |
| Industrial Ar / CO₂ / N₂ | 40 – 80 L | 2,200 – 2,640 | 48 – 60 | 8.5 – 10.0 | 55 – 95 | 25 – 60 |

Factory‑Level Quality & Compliance Infrastructure
Our facility in Zhuzhou, Hunan covers 12,000 m² with dedicated lines for cylinder forming, heat treatment, and valve assembly. We hold active certifications that US buyers routinely verify:
- ✔ ISO 9001:2015 — Quality management system (certified by SGS)
- ✔ DOT 3AA / 3AL — Design and test approval for US transport
- ✔ UN / ISO 9809‑1 — International gas cylinder standard
- ✔ CE / PED (Module B+D) — European Pressure Equipment Directive (for EU orders)
- ✔ FDA / NSF — Food‑grade materials for N₂O and CO₂ (cream chargers, beverage gas)
Every cylinder batch undergoes hydrostatic testing at 1.5× service pressure, 100% leak check, and internal drying. We provide COA (Certificate of Analysis), MSDS, and ECM (Export Certificate of Manufacture) with every shipment.
OEM/ODM Support & Commercial Terms for 2026

Which Gas Cylinder Size Fits Your Business Model?
Choosing the right cylinder size depends on your end‑use market. Here are three typical buyer profiles we work with:
🥤 Beverage Distributor
You need 2.5L to 10L CO₂ cylinders for soda fountains, kegerators, or carbonated water machines. Why standard 7.5L / 8L fits most US under‑counter units. MOQ 500, with CGA 320 valve. We supply with NSF‑certified food‑grade CO₂.
🍦 Cream Charger Importer
8g, 580g, 615g, 640g, 680g, 2000g — N₂O cylinders for whipped cream, culinary foams, and infusion. We are the largest integrated producer in Hunan. All units pass 18‑bar burst test. Private label available with your brand on the carton and cylinder.
💨 Industrial Gas Wholesaler
40L–80L high‑pressure cylinders for argon, oxygen, nitrogen, or ethylene. Used in welding, medical, and chemical industries. DOT 3AA rated, 2,200–2,640 PSI. We offer multi‑gas filling capability and custom bundle packing for container freight.
What Our US & International Buyers Say
Mark S.
Import Manager — BrewTech Distributors, Texas
“We source 7.5L CO₂ cylinders for our draft beer system clients. XingYe’s standard size matched our existing CGA 320 regulators perfectly. The MOQ of 500 was manageable, and the lead time was 24 days — exactly as quoted. 3rd order this quarter.”
Rachel H.
Brand Owner — WhipCream Pro, California
“Their OEM service for cream chargers is outstanding. We changed from a Chinese trading company to direct factory and saved 18% per unit. The laser engraving is clean, and the 615g tanks fill consistently at our partner station. Five star reliability.”
James P.
Sourcing Agent — GasLink International, Florida
“I have audited four cylinder factories in China. XingYe’s quality system is the most thorough for DOT compliance. Their documentation package — COA, MSDS, UN test reports — saves me weeks of paperwork. Currently shipping 40L O₂ cylinders to Miami.”
Akash R.
Wholesale Director — PrimeGas, Dubai
“We distribute ethylene gas for fruit ripening across the Middle East. XingYe’s 54L standard cylinder with CGA 580 valve works seamlessly with our filling manifold. The factory team helped us reduce valve leakage to under 0.3%. Strong recommendation.”
