If you are sourcing 45kg gas cylinders for industrial, food-grade, or medical gas applications, the first question is always: “What are the exact 45kg gas cylinder dimensions?” A standard 45kg LPG or industrial gas cylinder typically measures 375–380 mm in outer diameter (14.8–15.0 inches) and 1,200–1,250 mm in overall height (47.2–49.2 inches) including the valve protection ring. Tare weight ranges from 35 kg to 42 kg depending on the material and pressure rating. These dimensions directly affect your shipping container utilization, warehouse racking, and end-user handling compliance. Below we break down every specification, certification, and sourcing factor you need for 2026 procurement.
Why 45kg Cylinder Dimensions Matter — The Real Cost of Getting It Wrong
Production line at Zhuzhou XingYe Chemical — ISO 9001 certified facility
Every year, import managers and sourcing agents lose thousands of dollars in unexpected freight costs, warehousing fees, and compliance penalties because they assumed all 45kg cylinders share the same footprint. They do not.
A 0.5-inch deviation in diameter can mean 6 fewer cylinders per 20-foot container — a 12% loss in shipping efficiency. A height mismatch can shut down an entire racking system. And without proper certification documentation (DOT, TC, ISO 9809, or EN 1964), your shipment may be held at customs for weeks.
That is why reputable suppliers like Zhuzhou XingYe Chemical provide certified dimensional drawings, COA, and MSDS with every order — not just to satisfy documentation requirements, but to protect your logistics budget and project timeline.
45kg Gas Cylinder Dimensions — Complete Technical Reference (2026 Standard)
The table below consolidates the most common 45kg gas cylinder specifications used across LPG, CO2, N2O (nitrous oxide), and industrial gas applications. Always request a certified dimensional drawing for your specific gas type and pressure rating, as variations exist between manufacturers and local regulations.
| Parameter | Typical Range (Metric) | Typical Range (Imperial) | Notes |
|---|---|---|---|
| Water Capacity | 108 – 112 L | 28.5 – 29.6 gal | Depends on gas density & pressure |
| Outer Diameter (OD) | 375 – 380 mm | 14.8 – 15.0 in | Critical for container packing |
| Overall Height (incl. valve guard) | 1,200 – 1,250 mm | 47.2 – 49.2 in | Varies by valve type |
| Tare Weight (empty) | 35 – 42 kg | 77 – 93 lb | Steel vs. composite material |
| Filling Pressure (at 15°C) | 17 – 20 bar (LPG) | 247 – 290 psi | Varies by gas composition |
| Test Pressure (hydraulic) | 30 – 36 bar | 435 – 522 psi | Per ISO 9809 / EN 1964 |
| Valve Connection | POL / 25E / CGA 555 | — | Depends on regional standard |
| Material | 37Mn / 34CrMo4 steel | — | High-strength alloy steel |
| Certification | ISO 9809, EN 1964, DOT 3AA | — | Multiple standards available |
Disclaimer: Values shown are typical industry ranges. Final dimensions, weights, and pressure ratings depend on the specific gas type, cylinder manufacturer, and applicable regulatory code. Always refer to the certified drawing provided with your order confirmation.

Who Uses 45kg Gas Cylinders & Why Dimensional Accuracy Matters
| Industry | Application | Why Dimensions Matter |
|---|---|---|
| Food & Beverage | N2O cream chargers, CO2 carbonation | Racking systems in commercial kitchens have fixed slot sizes. A cylinder that is 10 mm too tall won't fit under a prep table. |
| Medical Gases | Diving oxygen, medical oxygen | Cylinders must fit standard hospital brackets and transport trolleys. Valve height also affects regulator connection. |
| Industrial Manufacturing | Argon, CO2 welding mixtures | Automated welding cells require consistent cylinder dimensions for robotic gas supply arms. |
| Hospitality & Catering | LPG for cooking, N2O for dessert preparation | Storage rooms are often compact. Cylinder diameter directly affects how many units fit per square meter. |
Trusted by Import Managers & Brand Owners Worldwide
Import Manager, Delgado Gas Supply, USA
"We switched to Zhuzhou XingYe for our 45kg CO2 cylinders after two shipments from our previous supplier showed diameter variances of nearly 8 mm. That might sound small, but it meant we couldn't load our standard pallet configuration. XingYe's cylinders have been consistent within 1.5 mm every time. Plus, their COA documentation makes FDA audits much smoother."
Brand Owner, Eathorne Cream Co., UK
"We needed OEM cylinders with our branding and a specific valve height for our filling line. XingYe's team sent a detailed dimensional drawing within 48 hours and delivered prototypes in 21 days. The production run matched the drawing exactly. Their food-grade N2O certification was also a major plus for our UK market."
Sourcing Agent, LatinGas Procurement, Chile
"Container utilization was my main concern. I calculated that XingYe's 45kg cylinder dimensions — 378 mm diameter — allowed us to fit 112 units per 40-foot container versus only 96 from a competitor. That's a 17% reduction in per-unit freight cost. The MOQ of 500 units was also flexible enough for our market testing phase."
Operations Director, Nordic Whip AB, Sweden
"We needed cylinders compliant with PED 2014/68/EU and with a specific tare weight for our rental pool. XingYe provided cylinders with actual tare weights within 0.8 kg of the stated value — far better than the ±2 kg we were getting before. Their logistics team also arranged sea freight to Gothenburg with full customs documentation."
Wholesale Buyer, Seoul Gas Distributors, South Korea
"Price was competitive, but what sealed the deal was the transparency. They shared a full dimensional DWG file before we even placed the order, and the production samples matched it perfectly. Lead time was 32 days — faster than the 45-day minimum quoted by other Chinese suppliers."

Frequently Asked Questions About 45kg Gas Cylinder Dimensions
Q: Are all 45kg gas cylinder dimensions the same across manufacturers?
No. While most 45kg LPG cylinders follow ISO 9809 or EN 1964 guidelines, actual dimensions vary between manufacturers by up to 10–15 mm in height and 3–5 mm in diameter. Always request a certified drawing from your supplier and verify against your container and racking specifications before ordering.
Q: What is the standard outer diameter of a 45kg LPG cylinder?
The most common outer diameter is 378 mm (14.9 inches), though you may find cylinders ranging from 370 mm to 385 mm. At Zhuzhou XingYe Chemical, our standard 45kg LPG cylinder has an OD of 378 ±1.5 mm, which optimizes container loading while meeting all safety standards.
Q: Can I get custom 45kg gas cylinder dimensions for OEM branding?
Yes, we offer OEM/ODM services including custom valve types (POL, 25E, CGA 555), branded painting, specific tare weight targets, and modified height for your filling line. Minimum quantity starts at 500 units for standard modifications. Contact our engineering team with your requirements.
Q: How many 45kg gas cylinders fit in a 20-foot or 40-foot container?
Based on our standard 378 mm diameter and 1,240 mm height: 48–54 units in a 20-foot container and 104–112 units in a 40-foot container, depending on stacking configuration and valve guard type. We provide a container loading plan with every quotation.
Q: What certifications do I need for importing 45kg gas cylinders into the USA?
For the U.S. market, cylinders must comply with DOT 3AA or 3A standards and be manufactured by a facility with DOT approval. We can provide cylinders with DOT-SP (Special Permit) numbers upon request. Additionally, if you are importing food-grade gases (e.g., N2O or CO2), FDA registration and food-contact material compliance are required. We include all relevant documentation.
