E Size Cylinder Dimensions Guide for Importers & Wholesalers (2026 Updated)
Published by David Chen, Senior Gas Cylinder Engineer at Zhuzhou XingYe Chemical Co., Ltd.
With over 15 years in industrial gas and cylinder manufacturing, David Chen leads quality control and product development for XingYe Chemical's global cylinder solutions.
E size cylinder dimensions are standardized for medical and industrial gas applications: typical height is 66″ (1,676 mm), diameter 7.25″ (184 mm), water capacity 60–70 liters, and service pressure 2,000–2,640 psi. For import managers and wholesalers sourcing E size cylinders from China, understanding exact dimensions, weight (~130 lbs empty), and connection types is critical for logistics, safety, and certification compliance. This guide provides verified specifications, market standards, and procurement insights to help you make informed bulk ordering decisions.
Why Accurate E Size Cylinder Dimensions Matter for Your Business
Importing gas cylinders involves navigating multiple standards (DOT, ISO, CE, ASME) and ensuring dimensional compatibility with your filling systems, storage racks, and end-user equipment. Common challenges include:
- Misaligned dimensions – cylinders that don't fit existing medical carts or industrial manifolds.
- Weight variations – affecting shipping costs and handling safety.
- Certification gaps – non-compliant cylinders blocked at customs or rejected by clients.
- Unreliable lead times – especially when sourcing from multiple suppliers.
Our E size cylinder dimensions are engineered to meet global standards, eliminating guesswork and reducing procurement risks.
Standard E Size Cylinder Dimensions & Technical Parameters
Below are the exact specifications for our E size high-pressure steel cylinders, manufactured in compliance with DOT-3AA, ISO 9809, and EN 1964 standards. All data is based on batch-tested production; please refer to the actual order confirmation for final tolerances.

Global Compliance & Certifications
Every cylinder we export meets or exceeds the following certifications, ensuring seamless customs clearance and end-user acceptance:
- DOT-SP / DOT-3AA – US Department of Transportation special permit and standard.
- ISO 9809-1:2019 – International standard for refillable seamless steel gas cylinders.
- CE (TPED / PED) – European transportable pressure equipment directive.
- GB/T 5099.1 (China) – National standard equivalent to ISO.
- COA (Certificate of Analysis) – For specialty gas fills (e.g., N₂O, CO₂, oxygen).
- MSDS – Material Safety Data Sheet provided with each shipment.
Our factory holds ISO 9001:2015 quality management system certification, and we conduct 100% hydrostatic testing on each cylinder before release.
