11 kg Gas Cylinder Dimensions: The Complete 2026 B2B Buyer’s Guide
For sourcing managers and brand owners, the 11 kg gas cylinder dimensions represent a critical specification that directly impacts shipping costs, storage density, and regulatory compliance in the USA market. A standard 11 kg N₂O or CO₂ cylinder typically measures 790 mm (31.1 inches) in height with a 230 mm (9.1 inch) outer diameter, varying slightly based on working pressure (200 bar vs 250 bar) and valve type (CGA 320 or CGA 580). This guide provides verified dimensional data, DOT compliance requirements, and procurement insights tailored for import managers and wholesalers.
Why Exact Cylinder Dimensions Matter for Your Business
A mismatch in 11 kg gas cylinder dimensions can disrupt your entire supply chain—from container loading efficiency to automated filling line compatibility. Common pain points faced by B2B buyers include:
- Freight optimization failure: Standard 20 ft containers hold approximately 144 units of 11 kg cylinders when properly nested. Dimensional variance below 1% can reduce this by 10–15%, increasing per-unit logistics cost.
- Customs & DOT holds: USA DOT 49 CFR 178 requires stamped dimensions on each cylinder. Inconsistent dimensions trigger re-inspection and demurrage fees.
- Valve/regulator incompatibility: Working pressure and thread pitch (CGA 320 vs CGA 580) must match. Incorrect valve selection can cause gas leaks and safety incidents.
- Storage & retail shelving conflicts: Wholesalers need cylinders that conform to standard pallet footprints (48" x 40") and rack heights.
Our USA clients consistently tell us that dimensional accuracy is the #1 factor in supplier selection—ahead of unit price. Here is how we address it.
Verified 11 kg Gas Cylinder Dimensions (DOT 3AA / ISO 9809)
Disclaimer: The following data represents standard values for our standard steel cylinders. Final specifications vary by working pressure and valve configuration. Please refer to the certified drawing in your order confirmation.
| Parameter | Metric Unit | Imperial Unit | Tolerance |
|---|---|---|---|
| Gas Capacity | 11 kg | 24.3 lbs | ±0.2 kg |
| Overall Height | 790 mm | 31.1 in | ±3 mm |
| Outer Diameter | 230 mm | 9.1 in | ±1 mm |
| Tare Weight | 14.5 kg | 32.0 lbs | ±0.5 kg |
| Water Capacity | 22.9 L | 6.0 gal | ±0.2 L |
| Working Pressure | 200 bar / 250 bar | 2900 / 3625 PSI | Per DOT 3AA |
| Valve Connection | CGA 320 / CGA 580 | — | Customer spec |
| Material | 34CrMo4 / 37Mn | — | ISO 9809-1 |
Key insight for US importers: The 200 bar version is most common for N₂O cream chargers, while 250 bar cylinders are preferred for high-purity CO₂ and industrial shielding gas. Always confirm the 11 kg gas cylinder dimensions with your filling plant—valve height alone can add 15–25 mm.
USA DOT Compliance & Certification Requirements (CFR 49)
Every cylinder entering the USA for commercial use must comply with DOT 49 CFR 178 or TC (Canada) standards. Here is what we provide for our 11 kg cylinders:
- DOT 3AA Stamp: Engraved serial number, specification, working pressure, and original test date.
- ISO 9809-1 Certification: Our Chinese factory holds ISO 9001 and ISO 9809-1, ensuring third-party audited quality.
- 5-Year Hydrostatic Retest: All cylinders pass a hydraulic pressure test at 1.5x working pressure.
- Burst Pressure Margin: Minimum 3.0x working pressure before rupture (exceeds DOT minimum).
- Material Traceability: MTC (Mill Test Certificate) for every heat of steel used.
Note for brand owners: If you are private labeling, we handle all DOT registration paperwork and can apply your company’s name as the "Importer of Record" on the cylinder shoulder stamp. This eliminates the need for re-branding.
Disclaimer: Certification requirements may change. Always verify current DOT exemptions with your legal counsel.
Our production line—every 11 kg cylinder is hydrostatically tested and visually inspected per DOT standards.
Our Manufacturing & Supply Chain Advantage
Zhuzhou XingYe Chemical Co., Ltd is a 10+ year professional factory integrating R&D, production, and sales. We are not a trading company—we own the tooling, the heat treatment lines, and the logistics network. Here is what this means for your 11 kg gas cylinder dimensions procurement:
15kg gas cylinder dimensions 11kg gas cylinder 45kg gas cylinder dimensions

Application Scenarios for the 11 kg Cylinder
| Industry | Gas Type | Typical USA Buyer | Volume/Month |
|---|---|---|---|
| Wholesale Cream Charger | N₂O 99.0% | Importer / Distributor | 2,000 – 10,000 units |
| Beverage Carbonation | CO₂ 99.9% | Brand Owner / Pub Group | 500 – 5,000 units |
| Industrial Welding | CO₂ / Argon Mix | Sourcing Agent / Warehouse | 1,000 – 8,000 units |
| Diving / Medical Oxygen | O₂ 99.5% | Wholesaler / Filling Station | 300 – 3,000 units |
The 11 kg size is particularly popular in the USA for N₂O cream charger refilling due to its balance of portability (31 lbs tare) and capacity (16,000+ whipped cream charges per cylinder).
What Import Managers & Wholesalers Say About Us
We have supplied over 200,000 11 kg cylinders to USA and European buyers since 2018. Here is feedback from recent clients:
James Miller
Import Manager, USA (Food Service)"Finally, a supplier who understands DOT specs. The 11 kg cylinders matched our filling equipment perfectly. The CGA 320 valves were exactly as ordered. We saved 16% on landed cost."
Sophia Alvarez
Brand Owner, Canada (Retail)"We needed OEM branding on 3,000 units for a Q4 launch. The team managed the logistics and compliance documentation seamlessly. The dimensions were spot on—no repackaging needed."
Michael O'Sullivan
Wholesaler, Ireland (Beverage)"Switching to XingYe saved us 18% on landed costs. The 11 kg dimensions perfectly fit our shipping pallets and warehouse racks."
Ethan Park
Sourcing Agent, USA (Industrial Gas)"Inspected the factory myself in 2024. They have the capacity and the quality control. The 11 kg cylinder spec sheet is highly accurate—within 0.5% tolerance."
Liam Scott

11 kg vs. Other Standard Cylinder Sizes
Understanding how the 11 kg gas cylinder dimensions compare to alternative sizes helps optimize your supply chain:
| Size | Height (mm) | Diameter (mm) | Tare Weight (kg) | Best For |
|---|---|---|---|---|
| 6.8 kg | 540 | 204 | 8.5 | Portable welding / diving |
| 10 kg | 750 | 229 | 13.0 | Beverage carbonation |
| 11 kg | 790 | 230 | 14.5 | N₂O bulk / Cream charger refill |
| 20 kg | 950 | 267 | 22.5 | High-volume CO₂ / welding |
The 11 kg cylinder occupies the sweet spot: it offers 60% more capacity than a 6.8 kg unit while only adding 6 kg of tare weight. This makes it the preferred choice for USA importers balancing shipping volume (more gas per container) and per-unit weight (under 50 lbs gross, ideal for handling).
Packaging, Logistics & After-Sales Support
Every cylinder is protected for international transit:
- Individual packaging: Thick PE bag + corrugated cardboard sleeve + wooden pallet or plywood crate.
- Container loading: We load under IPPC-certified pallets to avoid ISPM-15 issues at US customs.
- Shipping terms: FOB Shanghai / Ningbo, CIF Los Angeles / Long Beach, or DDP for consistent clients.
- After-sales: 12-month warranty against manufacturing defects (valve, paint, and material).
We also supply custom CGA valves, collar rings, and cap gaskets to support your refilling station setup.
Final QC check—every cylinder is pressure tested and visually inspected before packaging.
