50 Litre Gas Cylinder Dimensions: The Complete Technical Guide for B2B Buyers
When sourcing 50 litre gas cylinder dimensions for industrial or food‑grade gases, understanding the exact measurements is critical for transportation, storage, and compatibility with filling systems. A standard 50‑litre steel gas cylinder typically measures 51.2 inches (1300 mm) in height and 10.8 inches (274 mm) in diameter, with a tare weight of approximately 110 lbs (50 kg). These parameters vary by gas type, pressure rating, and country‑specific regulations – this guide provides comprehensive specifications to help import managers, wholesalers, and OEM buyers make informed decisions for their supply chain.
Industry Pain Points: Why Accurate Dimensions Matter
Importers and brand owners often face challenges such as:
- Transportation inefficiencies: Mismatched dimensions lead to wasted container space or damaged cylinders during shipping.
- Regulatory non‑compliance: Each country (e.g., USA DOT, EU TPED) has strict dimensional standards; a few millimeters can delay customs clearance.
- Storage & handling issues: Warehouses and filling stations require consistent dimensions for rack systems, dollies, and valve connections.
- OEM/ODM integration: When you design custom gas equipment (e.g., manifolds, cabinets), cylinder dimensions must be precise to avoid costly rework.
A reliable supplier provides not only the cylinder but also the certified dimensional data that eliminates these pain points.
Standard 50 Litre Gas Cylinder Dimensions (Metric & Imperial)
The table below lists the typical dimensions for a 50‑litre cylinder designed for industrial and food‑grade gases (e.g., N₂O, CO₂, O₂, Argon). Please note: final dimensions may vary by ±2 mm based on manufacturing batch and specific gas service; always confirm with your order.
| Parameter | Metric | Imperial (approx.) |
|---|---|---|
| Total Height (including valve guard) | 1300 mm | 51.2 in |
| Height of Cylinder Body (without valve guard) | 1160 mm | 45.7 in |
| Outer Diameter | 274 mm | 10.8 in |
| Wall Thickness (typical) | 6.5 mm | 0.26 in |
| Tare Weight (empty) | 50 kg | 110 lbs |
| Water Capacity | 50 Litres | 13.2 gal |
| Test Pressure | 250 bar / 300 bar (depending on gas) | 3,625 psi / 4,351 psi |
| Working Pressure (nominal) | 200 bar / 150 bar | 2,900 psi / 2,175 psi |

Compare: 50L vs Other Common Sizes
To help you plan your container loading, here’s a quick comparison of the 50‑litre cylinder with other popular sizes used in the USA and Europe:
| Size | Height (mm) | Diameter (mm) | Empty Weight (kg) | Common Gas |
|---|---|---|---|---|
| 40L | 1150 | 232 | ~42 kg | O₂, Ar |
| 50L | 1300 | 274 | ~50 kg | CO₂, N₂O, C₂H₄ |
| 60L | 1400 | 274 | ~58 kg | CO₂, N₂ |
| 80L | 1500 | 274 | ~70 kg | Industrial mixes |
The 50‑litre cylinder offers an excellent balance between capacity and portability, making it the preferred choice for medium‑volume applications.
